Computational homogenization is an approach which has been widely used for the study of heterogeneous materials. Multi-scale analysis stands for the coupling between the scales, the simulation of a complex pattern of a microscopic structure and eventually the usage of the required information in a macroscopic, structural scale. In this framework, a numerical scheme is initially presented, for the investigation of masonry structures. The heterogeneity induced by the bricks and the mortar joints, is taken into account with a simplified numerical homogenization model, applied for elastic material properties. Next, a multi-scale contact computational homogenization model is presented, for the study of composite materials. Thus, a nested numerical scheme consisted of two boundary value problems, is considered. The main idea of the proposed approach is related to the implementation of a classical unilateral contact law, in the microscopic scale of the problem. This can be considered as an initial step towards coupling computational homogenization, in a fem2 sense, with contact mechanics.
