Two-scale modeling of periodic metal matrix composites reinforced with metallic inclusions is presented in this paper. The adaptive finite element method (FEM) is used to approximate solutions of elastic or inelastic problems at both levels in order to improve efficiency of computation. Mesh adaptation at the macroscale is more challenging, since each refinement introduces new representative volume elements for which the loading history is typically unknown but necessary for further computation. At the microscale, the mesh adaptation enables generation of the initial discretization independently of the material heterogeneity.
