Numerical Issues in Plasticity Models for Granular Flows
Abstract
Friction plays a fundamental role in the Mechanics of granular materials. Two problems are considered: (i) heap formation, (ii) granular flow. Both problems admit closely related mathematical models. In each case, analytical and numerical difficulties are discussed. Efficient and reliable numerical methods are proposed and implemented. The results are illustrated by several computational experiments.
