Deformation and failure of crystalline rock and an elastoplastic homogenization theory

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

Rock and rock masses are composed of discrete elements of microstructures such as different grains and microcracks. In this study, first we show experimental results that a propagation, coalescence and increased density of microcracks cause mesoscale and macroscale cracks, and that elastic and plastic properties of rocks are significantly affected by these microstructures. Next, a homogenization theory to model the elastoplastic behavior of the material with microscale structure is presented.
