A TWO-SCALE FEM FORMULATION FOR HETEROGENEOUS MATERIALS

This article proposes a two‐scale finite element approach for the dynamic response of heterogeneous materials. While common two‐scale Finite Element Method (FEM) formulations consider the Representative Volume Element (RVE) much smaller than the finite element mesh, the present paper extends the formulation for the cases when RVE becomes comparable with the finite element in the mesh. The new two‐scale equations and their FEM implementation, are presented together with an example.
