Abstract
There are many advantages to micromechanical models of material response. These are models that predict the behavior under load of materials by considering the behavior of microscopic structures embedded in an equivalent continuum1,2. We have derived a theoretical model framework that allows quasistatic plastic pore crush and brittle fracture along three orthogonal sets of crack planes. The contribution of internal energy to the stress is included. We discuss the model, a numerical solution method, and a sample application problem, namely response of rock to an underground explosion.
