A COMPUTATIONNAL APPROACH TO HANDLE COMPLEX MICROSTRUCTURE GEOMETRIES

Résumé

Multi-scale analysis of components usually leads to solving micro-structures with complex geometries (composites, textiles, reinforced concrete, ...). The finite element analysis of such fine scales is tedious since the mesh must conform to material interfaces, voids, cracks,... In this presentation, we propose to use the " eXtended Finite Element Method " (X-FEM) as way to avoid complex meshing of microstructures. With the X-FEM, the physical surfaces do not need to meshed. Moreover, since it is based on the finite element method, extension to nonlinear constitutive laws is straightforward.
