Abstract

This study presents a peridynamic unit cell approach to predict the effective properties of microstructures in the presence of many defects and voids, and complex heterogeneity. It permits arbitrary number of constituent materials, voids and cracks. The constituent materials can have orthotropic response to account for deformation coupling. Voids and cracks can be modeled by simply breaking the peridynamic bonds between the material points. Also, the periodic boundary conditions are applied in a natural way without any constraint conditions. Furthermore, it leads to the determination of a damage matrix necessary for progressive failure analysis.
