Abstract

Based on theory of plasticity for porous media using finite element computer simulation the deformed state near spherical indenter has been studied for different mechanical properties of indented material. Porosity distribution near indenter depending on properties of porous body and friction conditions between indenter and porous body has been analyzed. Load profiles as a function of dilatancy tendency and contact friction has been shown. Development of bulk around indenter and its shape has been investigated.
