L’Axe de recherche « Nouveaux Matériaux, Systèmes Intelligents et Entreprises innovantes » organise ses travaux autour de quatre sous-axes de recherche majeurs :
La recherche de matériaux intelligents fonctionnels représente un défi majeur dans de nombreux domaines tels que l’automobile, l’aéronautique et la biomédecine. Dans ce contexte, nos chercheurs collaborent en mettant en commun leur expertise pour concevoir des métamatériaux bio-inspirés architecturés et des smart matériaux, depuis la phase de conception numérique jusqu’à l’optimisation des propriétés structurales et/ou fonctionnelles, en passant par la fabrication et la caractérisation expérimentale. Les technologies développées réunissent des compétences dans plusieurs domaines, notamment la modélisation et simulation numérique multi-échelles, la simulation par éléments finis, l’Intelligence Artificielle, l’impression additive, le smart manufacturing et les méthodes expérimentales.
Dans le cadre de la transformation numérique, la sécurité digitale joue un rôle primordial. Au sein de l’Axe ce thème englobe la cybersécurité, la sécurité des réseaux, la résilience et la cryptographie, revêtant une importance significative avec une visibilité à la fois nationale et internationale. Le deuxième thème porte sur les systèmes intelligents, qui sont des composantes essentielles de la transformation numérique. La recherche au sein de l’Axe dans ce domaine se concentre sur les interactions entre l’humain et la machine, que ce soit du point de vue visuel, audio et/ou tactile, ainsi que sur la robotique, les objets connectés, l’IoT, la réalité virtuelle, et la e-santé, en lien avec les récentes avancées de l’intelligence artificielle.
La manière d’organiser l’innovation et l’impact des innovations sur nos vies sociales, comportementales et organisationnelles revêtent une importance cruciale tant sur le plan théorique que pratique. Nos membres excellent à l’échelle internationale dans la compréhension et l’exploration du développement de nouveaux produits et processus, ainsi que dans d’autres domaines tels que la gestion des innovations technologiques, l’encouragement du talent, l’optimisation de la chaîne d’approvisionnement, la gestion avancée des entrepôts et des opérations, la promotion de marques, et l’impact qu’ils apportent aux individus, aux groupes et aux pays grâce à ces innovations. Nous avons également acquis une expertise dans le financement, le recrutement et le développement d’entreprises innovantes (entrepreneuriat et création de nouvelles entreprises).
Nous sommes très intéressés par la recherche de stratégies qui favorisent, promeuvent et gèrent les innovations dans ce monde numérisé et hyper-connecté. Nos membres se consacrent à l’étude de la stratégie numérique et de la transformation numérique, les ethnographies des phénomènes numériques (par exemple, la ludification, la blockchain, la gestion algorithmique), la psychologie dans un contexte numérique (affects et émotions dans l’espace numérique), le marketing numérique, les interactions numériques et sociales (via les dispositifs portables, la robotique, l’apprentissage profond, les jeux, etc.), ainsi que par l’analyse des modèles économiques existants et de l’évolution des entreprises innovantes.
Parmi les projets interdisciplinaires, nous incluons :
L’équipe d’enseignants-chercheurs Nouveaux Matériaux, Systèmes Intelligents et Entreprises innovantes.

A partir d'une démarche abductive, nous montrons que la mise en place de collectifs de femmes, dans la phase ante-création, est génératrice de confiance en soi. Le caractère bienveillant, empathique et non compétitif du groupe exclusivement féminin facilite, pour certaines femmes candidates à la création, la déconstruction de stéréotypes de genre sur l'entrepreneuriat féminin et atténue le sentiment de culpabilité lié à la difficulté à concilier projet entrepreneurial et vie familiale. En d'autres termes, la participation de la femme potentiellement créatrice à un collectif féminin répond à un besoin psychologique d'approbation externe qui peut faire défaut, notamment au sein de la famille. Toutefois, la pratique de l'accompagnement collectif au féminin dans la phase ante-création présente certaines limites. Ces dernières résultent de l'importance accordée par certaines femmes à la mise en place d'un environnement mixte pour le partage d'expériences entrepreneuriales diverses et le développement de réseaux d'affaires.},

It can be asserted that dental production center milling machines offer a wider range of materials and types of restoration shapes than labside solutions, while labside solutions offer a wider range than chairside solutions. The accuracy and integrity of restorations may be improved as a function of the embedded technologies provided. However, the more complex the technical solutions available, the more skilled the user must be. Investment cost and interoperability with third-party software increase according to the quality of the embedded technologies implemented. Each private dental practice may decide which fabrication option to use depending on the scope of the practice.},

rehabilitation of the tooth in order to fulfil functional

biomaterial achieves the manufacture of such
prosthesis. The milling process generates a
characteristic ?signature? on the prosthesis shape
called surface integrity. [1-3] Surface integrity is well
known and investigated in mechanical engineering
applications [2], but not well understood in restorative
dentistry. Several requirements of the prosthesis
surface such as aesthetics, biological response and
mechanical behaviour are influenced by the residual
roughness after milling. For each requirement, a
specific roughness might be manufactured in different
area of the prosthesis. [4-5] The main difficulty for
fixed partial denture manufacturers is to integrate the
different expected roughness during numerical
controlled milling process parameters choice. This
paper aims at providing a tool to help in predicting the
prosthesis roughness after milling.},

CAD/CAM dental practice can be considered as the handling of devices and software processing for the almost automatic design and creation of dental restorations. However, dentists who want to use dental CAD/CAM systems often do not have enough information to understand the variations offered by such technology practice. Knowledge of the random and systematic errors in accuracy with CAD/CAM systems can help to achieve successful restorations with this technology, and help with the purchasing of a CAD/CAM system that meets the clinical needs of restoration.

abstract = {Statement of problem. Computer-aided design/computer-aided manufacturing (CAD/CAM) machining influences the surface roughness of dental restorations and tool wear. Roughness must be suitable to meet clinical requirements, and the tool must last as long as possible. Purpose. The purpose of this pilot study was to investigate the influence of the CAD/CAM toolmaterial couple on tool wear and surface roughness after milling. Material and methods. Three tools (Lyra conical tool Ø1 mm; GACD SASU, Lyra conical tool Ø1.05 mm; GACD SASU, and Cerec cylinder pointed tool 12S; Sirona Dental Systems GmbH) and 3 CAD/CAM materials (Lava Ultimate; 3M ESPE, Mark II; VITA Zahnfabrik H. Rauter GmbH, and Enamic; VITA Zahnfabrik H. Rauter GmbH) were tested. The tool wear of 6 tool-material couples at a feed rate of 2 m/min was analyzed before and after 8 minutes of flank and climb milling with optical and scanning electron microscopy (SEM) observations and tool weighing. The surface roughness after milling was observed for 9 tool-material couples for flank and climb milling. Feed rates of 1, 2, 3, and 4.8 m/min were used for each couple. Ra, Rt, Rz, Sa, Sq, and Sz roughness criteria were measured. A paired comparison of tool-material couples was conducted with the Kruskal-Wallis test. Results. The Mark II material led to more severe tool wear. Milling of Lava Ultimate resulted in chip deposits on the tool grit. The Cerec cylinder pointed tool 12S was less worn for each material tested. The Cerec cylinder pointed tool 12S and the Lyra conical tool Ø1.05 mm provided similar roughness measurements for the 3 materials tested. The Lyra conical tool Ø1.05 mm tool provided better roughness than the Lyra conical tool Ø1 mm tool for the Enamic material. Conclusion. Tool lifetime calculated by volume of milled material removed should be the measure
provided by CAD/CAM manufacturers instead of a number of blocks. This tool lifetime should be
provided for the milling conditions associated with the material milled. Material hardness and tool grit are key factors for achieving a given roughness.},

The purpose of this work is to investigate the residual stress distribution induced by laser shock process-
ing in a 2050-T8 aeronautical aluminium alloy with both X-ray diffraction measurements and 3D finite
element simulation. The method of X-ray diffraction is extensively used to characterize the crystallo-
graphic texture and the residual stress crystalline materials at different scales (macroscopic, mesoscopic
and microscopic).
Shock loading and materials' dynamic response are experimentally analysed using Doppler velocimetry
in order to use adequate data for the simulation. Then systematic experience versus simulation compar-
isons are addressed, considering first a single impact loading, and in a second step the laser shock
processing treatment of an extended area, with a specific focus on impact overlap. Experimental and
numerical results indicate a residual stress anisotropy, and a better surface stress homogeneity with
an increase of impact overlap.
A correct agreement is globally shown between experimental and simulated residual stress values,
even if simulations provide us with local stress values whereas X-ray diffraction determinations give
averaged residual stresses.},

abstract = {The success of related diversification is not a given. Although synergies between a firm's businesses may exist, problems can arise in the sharing of key resources and capabilities as the firm attempts to exploit the synergies. To achieve success in related diversification, firms often leverage their organizational slack, or resources and capabilities that are in excess of the level demanded by their normal operations. However, sharing is difficult when firms have insufficient organizational slack, and this can lead to an overstretching of shared resources. Through case study methodology, this paper investigates how one technological SME managed its limited organizational slack while engaged in related diversification. Particular attention is given to the mechanisms that contribute to diversification failure. Consideration is also given to how the capability life-cycle may affect capability sharing in related diversification efforts.},

abstract = {In the present work, we propose a methodology to compute the response of structures
made of heterogeneous, random elastoplastic composites. The effective constitutive law is
provided by an incremental homogenization method (see e.g. [1]), which allows computing
very efficiently the stress-strain relationship at the integration points of the structure with-
out local calculations on the RVE. The accuracy of the method is enhanced by identifying
the coefficients of an empirical model related to the matrix, which provides a correction to
the initial incremental homogenization scheme solution. For this purpose, the size of the
RVE is determined for local microstructures consisting into random distribution of elastic
cylinders or pores in a von Mises elastoplastic matrix with nonlinear hardening. Unlike
previous approaches (see e.g. [2, 3]), we determine the size of the RVE by performing
a statistical convergence analysis not on the response of the microstructure, but on the
parameters of the empirical model used for the identification. Numerical results are pro-
vided to demonstrate the accuracy and the efficiency of the technique through structure
examples.},

abstract = {In the present work, a computational method is proposed to compute the response of
highly heterogeneous structures through a simplied (homogenized) model when no scale
separation can be assumed. Based on a recent theory developed by the authors [1, 2],
a nonlocal constitutive law is rst constructed based on numerical computations on a
unit cell. The homogenization framework is based on the use of linear lters instead of
classical averaging operators and generalizes the classical homogenization theory, leading
naturally to a nonlocal constitutive law. A numerical procedure is developed to compute
the response of structures made of periodic cells by using a coarse mesh, associated to
a wavelength related to a chosen scale of description. Compared to our previous work, a displacement-based strategy is proposed to implement the constructed nonlocal
law in a classical Finite Elements procedure related to the coarse mesh. Unlike other
nonlocal elasticity theories, the present method is fully micro-mechanically-funded and
re-localization can be achieved to analyze local (strain and stress) elds without solving
the fully detailed problem. The methodology is demonstrated by analyzing the response
of structures with heterogeneities which have characteristic dimensions comparable to
those of the structure itself.},

Three diamond burs and three dental biomaterials (ceramic, polymer, hybrid) were tested. The surface roughness was observed for nine tool-material couples in flank and top milling. Ra, Rt, Rz, Sa, Sq, Sz roughness criteria were
measured. It has been concluded that in flank milling the
measured surface roughness is in direct proportion to the diamond tool grain size. In top milling, the roughness is mainly due to the diamond grain size, and the radial depth is not a predominant parameter. The surface roughness was influenced by material hardness in flank milling mode. Moreover, the surface roughness was not affected by the feedrate.},

Employing a panel dataset at the aggregate country-level, the study is conducted using the generalised least squares (GLS) model.
The findings suggest that Indian FDI patterns vary over time in line with Indian economic and structural transformations. The patterns also differ between the home country groups in line with their economic development and geographic location relative to India. The desirable patterns of Indian inward FDI are determined not only the development levels of both host and home countries but also the host country's factor endowment pattern.
It is important for the Indian government to formulate selective targeting FDI policies to maximise economic impact of inward FDI by attracting more desirable efficiency-seeking FDI for higher economic growth.},

sandwich plates with various boundary conditions and it is well adapted to parametric
and optimization studies. First, a parametric study was conducted to choose the objective
function, the constraints, and the pertinent design variables to use in the optimization
problem which consist in reducing the sound power transmitted by a viscoelastically
damped sandwich plate. Next, by constraining the acoustical behavior of the sandwich panel,
the surface mass of the sandwich structure was minimized. It is shown that a significant
reduction in the transmitted sound power can be achieved by selecting the appropriate
geometric configuration and damping layer material.},

method [1] which has been successfully applied to solve contact problems with finite deformations. The
enforcement of contact constraints is applied in a weak sense throughout the contact interface. In this work,
we describe several techniques for solving contact problems using the mortar approach. The penalty
technique [2], the Lagrange multipliers method [2-3] and the augmented Lagrangian formulation [4-5] are
used for solving various numerical problems. A simplified algorithm is described to implement these types of

In addition, this method alleviates the
limit of the contacting mesh interpolation order and passes the patch test.

High beta elliptical cavities are thus of concern and, to achieve required performances for such resonators, surface preparation including electropolishing is recommended. We have designed and operate a setup for electropolishing in the vertical position of multicell cavities in order to: (i) obtain high yield with large elliptical cavities for Superconducting Linac (SPL) or European Spallation Source
projects; (ii) develop a reference installation demonstrating that this process is appropriate for the large scale treatment of cavities in industry. The setup described here is the first one able to electropolish vertically multicell cavities with circulating acid and high safety standards. This equipment makes it possible to use a wide range of parameters such as voltage, acid flow rate, temperature, and nitrogen injection with an R&D purpose in mind. Optimization is studied using modeling with COMSOL software for different cavities. As examples, we present some results for the 704 MHz high-beta SPL cavity and the 1300 MHz International Linear Collider cavity and show the influence of cathode shape on both acid flow and electric field distribution during the process. Importance of the size of the cavity and first results achieved on single-cell and nine-cell cavities will be discussed.},

L'entrepreneuriat international a été initialement appréhendé dans le cadre des entreprises « Born Global » (Rennie, 1993 ; Sharma et Blomstermo, 2003 ; Knight et Cavusgil, 2004 ; Rialp et al., 2005) ou « International New Ventures » (McDougall et Oviatt, 1994, 2005 ; McDougall et al. 1994). Cette attractivité tient beaucoup à ce qu'il profite d'une fertilisation croisée de deux champs de recherche : l'Entrepreneuriat et le Management International (McDougall et Oviatt, 2000). Ce champ récent est encore en plein développement, comme en témoignent la création en 2003 de la revue Journal of International Entrepreneurship et l'organisation annuelle de la Conférence internationale en entrepreneuriat international de l'Université de McGill. En France, un groupe thématique de recherche dans ce domaine a été mis en place en mai 2011 au sein de l'Académie de l'Entrepreneuriat et de l'Innovation. L'essor des recherches en EI se comprend empiriquement par la multiplication en parallèle au cours de ces dernières années du nombre de PME se lançant à l'assaut des marchés étrangers, même si les statistiques sont encore rares sur le sujet (OCDE, 2008 ; Coeurderoy et Bacq, 2012).},

between innovation and internationalization for small to medium-size businesses. The relationship between the two
is mutually beneficial when penetration of new overseas markets takes place as a result of the competitive advantage
generated by innovation. In the same way, internationalization facilitates the optimization of innovative strategy
generating either an accelerated return on research and development costs or access to overseas technological
resources. To combine both domestic and overseas resources and competencies is, in effect, likely to generate an
additional technological advantage. Seen from this perspective, the internationalization process can be said to be a
catalyst for innovation. However, the consumption of resources and the need for expertise generated by the
simultaneous pursuit of these two development strategies can lead to conflict and constraint for an SME in terms of
allocation of both resources and competencies. The relationship between innovation and internationalization can
therefore become antagonistic.},

abstract = {By using the example of piggyback arrangements, we focus on the strategic issues of partnerships between exporting innovative SMEs and MNEs on foreign industrial markets. This research looks at two types of managerial contributions. On the one hand, it highlights co-marketing practices for an accelerated penetration and learning of a new foreign market for the SME. On the other hand, it stresses the importance of developing a sustainable management of partnership resources for the MNE in order to rapidly cover new market needs thanks to complementary products from small innovative firms.},

abstract = {We study the version of the asymmetric prize collecting travelling salesman problem, where the objective is to find a directed tour that visits a subset of vertices such that the length of the tour plus the sum of penalties associated with vertices not in the tour is as small as possible. In Dell'Amico et al. (1995), the authors defined it as the Profitable Tour Problem (PTP). We present an (1 + ?log( n )?)-approximation algorithm for the asymmetric PTP with n is the vertex number. The algorithm that is based on Frieze et al.'s heuristic for the asymmetric travelling salesman problem as well as a method to round fractional solutions of a linear programming relaxation to integers (feasible solution for the original problem), represents a directed version of the Bienstock et al.'s (1993) algorithm for the symmetric PTP.},

abstract = {The constrained-layer damping treatment is widely used to control the resonant response of vibrating structures,
particularly in the automotive and aerospace industries. This technique requires design tools in order to select the
best location, type and thickness of the damping and constraining-layer materials for optimum damping while
minimizing the total weight of the damping treatments. In this study, a numerical tool is presented to analyze the
vibration response of plates partially or fully covered with a constrained viscoelastic damping material. This tool
is based on a finite element approach. The undamped plate structure is modeled using a discrete Kirchhoff theory
(DKT) element. However, a sandwich plate element is specially derived to model the damped plate structure.
This element is formulated in such a way that it is compatible with the DKT element. The natural frequencies
and modal loss factors are derived from the modal strain energy method. The proposed approach is validated
by comparing predictions with the results of various examples published in the literature. Hence, this approach
is shown to predict accurately the damping characteristics of arbitrarily shaped sandwich plates, with different
material properties and boundary conditions, fully or partially covered with constrained viscoelastic layers. The
influence of the damping patch locations and the viscoelastic material's shear modulus on the vibration and
damping characteristics is investigated. To damp the plate effectively using partial coverage, the damping patches
must be distributed appropriately. To select the best damping patch locations, an indicator based on the energy
dissipated through the viscoelastic layer is proposed.},

abstract = {Reproducible operation at high performances of sc cavities is required for superconducting linacs, at least in their high energy section in the case of accelerators for proton beams. High beta elliptical cavities are thus of concern, and, to achieve required performances for such cavities, surface preparation including electro-polishing (EP) is recommended. Moreover, for large dimension cavities we consider the EP treatment in vertical configuration (abbreviated as VEP) to be more appropriate. For this reasons, a VEP set-up has been designed at Saclay for the electro-polishing of muticells elliptical cavities. Chosen equipment will make it possible to use a wide range of parameters (voltage, flowrate, temperature, nitrogen inerting) with R&D purpose in mind.
Optimization will be done using modeling with COMSOL software for different cavities. As examples, we present some results for the 704 MHz high-beta SPL cavity and the 1300 MHz ILC cavity and show the influence of cathode shape on both acid flow and electric field
distribution during the process. At last, importance of the size of the cavity will be commented.},

abstract = {La durabilité de l'avantage concurrentiel dépend de la capacité de l'entreprise à entretenir le caractère inimitable de ses compétences distinctives (Carpenter, Sanders, 2007). En d'autres termes, l'entreprise lutte constamment contre les facteurs d'homogénéisation sectoriels des compétences à l'origine de l'avantage concurrentiel. Le présent article recense les principaux facteurs explicatifs de l'homogénéisation des compétences et identifie les barrières à leur imitation. Une lecture dynamique du processus d'imitation au sein d'un secteur est proposée dans une première partie. L'analyse se base sur le concept du cycle de vie de la compétence. La deuxième partie insiste sur trois catégories de facteurs explicatifs de l'homogénéisation des compétences : la recherche de l'efficience, le développement d'un consensus cognitif entre concurrents et la maturité du secteur. Cette homogénéisation peut néanmoins être réduite via l'institution de barrières à l'imitation des compétences. Enfin, une analyse des tensions subies par le secteur en fonction du degré d'innovation implémentée par les acteurs est exposée en dernière partie.},

constrained-layer damping treatment. This formulation takes into account the effects of fluid loading.
The governing coupled structural/acoustic equations of motion are solved using a modal approach combined
with an interpolation technique of the reduced radiation impedance matrix components of the
fluid. The numerical results show the accuracy of the proposed approach. In addition, a parametric study
is carried out to highlight the influence of geometrical and material variables on the damping characteristics,
which could be used as design parameters for the optimization problem.},
