Abstract
This work presents a new mean-field approach for the modeling of two-phase elasto-plastic composites. Themultisitemodelwas initially designed for texture prediction in polycrystalline aggregates [L. Delannay et al., Comput. Mater. Sci. (2008), doi:10.1016/j.commatsci.2008.06.013]. Here, it is used to simulate short range interactions between the matrix and the inclusions. Stacks of two subregions lying on either sides of a planar interface are treated as pseudograins. A self-consistent scheme governs the strain partitioning among the pseudo-grains and the remaining matrix. Predictions of the model are compared to finite element results.
