A Numerical Model for Simulation of Dry Powder Compaction
T. Erhart, W. Wall, and E. Ramm. Proc. of the 21st CAD-FEM users' meeting, Potsdam, Germany, (2003)
Abstract
In this paper, a continuum model for the simulation of dry powder under quasi-static as well as dynamic loading will be presented. It is implemented in the context of multiplicative hyperelastic-based finite strain elasto-plasticity in a Lagrangean framework. A nonsmooth multisurface plasticity with tension cutoff, Drucker-Prager failure envelope and strain hardening cap provides the reproduction of the relevant phenomena: tensile failure, material flow under shearing and compaction under pressure. Corresponding material parameters are determined by geotechnical experiments like uniaxial and triaxial compression tests. The results of quasi-static simulations are compared with experimental results.
