Numerical Simulation of Compacting of Powder Parts having Slant to a Pressing Direction Surfaces

摘要

The internal version of a finite element method is used at simulation of powder parts pressing processes. The modified relations of porous body plasticity theory are applied to exposition of powdered material properties. Rigid - plastic behaviour of material has been considered. The study of the density distribution is of the main interest of the present paper. Effect of both contact friction forces direction and of the pressing scheme on the final properties of the compacts have been investigated. Two-layer parts compacting is also studied. The results of numerical simulation and experimental data are compared.
