Part of the CISM International Centre for Mechanical Sciences book series (CISM, volume 480)


The chapter presents some aspects of a mathematical modeling of the plastic behavior of saturated porous materials by a micromechanics approach. The general format of poro-plasticity is concluded by splitting the local elastic-plastic problem, stated for a representative volume element, into two ones corresponding to the elastic- and residual state of the solid, respectively. Making use of an appropriately defined comparison analysis, the so-called effective stress concept is verified.
