Abstract
Isostatic pressing of porous ceramic material in a container is considered. Simulation of the process is based on flow theory with smooth potential. It is aimed at studying the shape change phenomenon. The effect of various factors including initial density and dimensions as well as rheological characteristics is considered. When the ceramic material approaches a rigidly-plastic condition and container material flow is controlled by a linear viscous mechanism shape change is more marked.
