Indentation of Irreversibly Compressible Material: Computer Simulation

Abstract

Based on the theory of plasticity for porous bodies and using finite-element computer simulation, the deformed state near spherical and conical indenters has been studied for different mechanical properties of indented material. Porosity distribution near the indenter depending on the properties of a porous body and friction between the indenter and porous body has been analyzed. Load profiles as a function of tendency to dilatancy and contact friction are shown. The development and shape of bulks around the indenter have been studied.
