MECA

The Mechanics team possesses strong and recognized expertise in its two main research areas: on the one hand, the theoretical and numerical multi-scale modeling of heterogeneous structures and materials, and on the other hand, the quantification of uncertainties in mechanics and the dynamics of coupled structures and systems. For these two themes, the team has well-established know-how and recognized expertise, granting it an excellent position at both the national and international levels, as evidenced by numerous awards and invitations to conferences, as well as requests for national or industrial collaborative projects on these topics.

More specifically, the team asserts its originality compared to many other research groups on these subjects at the national and international levels, particularly through the following specialized expertise: the development of scale transition techniques, nonlinear multi-scale modeling with multiphysics coupling and consideration of gradient effects in heterogeneous materials, modeling of cracking in heterogeneous materials, interface modeling, metamaterial modeling, acoustics of porous media, uncertainty quantification, optimization problems under uncertainty, and the development of advanced mathematical modeling tools in mechanics.

A final originality to mention is the team’s involvement in cross-disciplinary projects within the laboratory, including other teams (theoretical chemistry, biomechanics, heat and mass transfer), which has enabled it to acquire skills in multidisciplinary research areas such as nanomechanics, biomechanics, or problems involving solid and fluid mechanics.
