Multi-physics and multi-model approaches : Dialogues between models across space-time scales   

  • Co-simulation and asynchronous heterogeneous time integrators: application to low-energy impacts on composite structures, earthquake-type stresses on nuclear overhead cranes.

  • Coupling of models at several spatial scales for shape optimisation: link between CAD geometry, IGA calculation model and optimisation model. Application to thin stiffened aeronautical structures.

  • Coupling models from the atomic scale to the continuum scale: application to nanocomposites under transient dynamic THz stress (metallic glasses in the presence of nanometric inclusions).
