In order to use an effective meso-scale model as a basis for deterministic large-scale structural analysis and stochastic simulation, it is important to evaluate the sensitivity of these meso-scale models. Particularly, the way plastic behavior is described at the meso-scale level must be considered. In the study, a single analytical criterion model was developed and tested against various elastoplastic meso-scale models for accuracy of the criterion. Present research will be an extension of the single content model. The problem is to examine the effect of meso-scale models to capture the interaction between flow fields in a multi-material material. The micro-structures are investigated taking into account the plasticity of the contents and the bonding of these plastic regions under increasing load. In this work, the main purpose is to examine flow patterns. The moving window generalized cell method is a technique used to perform meso-scale homogenization.
