Computational homogenization methods allow circumventing issues associated to analytical or semi-analytical approaches, for predicting the effective behavior of heterogeneous materials whose phase are described by a nonlinear behavior, more precisely when microstructures have complex morphologies or a history-depedendent behavior, or when considering finite strains. In this work, several contributions to computational homogenization methods for modeling nonlinear heterogeneous materials are proposed. In a first part, we introduce a method for homogenizing meterials whose phases are perfectly elastoplastic. The technique extends the Non Uniform Transformation Field Analysis (NTFA) method by développing a return-mapping algorithm to update ...
