Abstract

The first requirement in the calculation of problems in mechanics is a formulation of the material behavior. The material description should include elastic, elastic-plastic, and hydrodynamic flow. Appropriate yield criteria must be employed. The literature includes many complicated forms to describe material behavior, some of which have been developed to aid the mathematics in the analytical solution of the equations of motion. However, since numerical techniques are considered here, the equations of motion are completely independent of equations that describe material behavior, and any mathematical form may be used. The objective of the material models is to provide a theoretical description applicable to a wide class of practical problems, but using simple idealizations of the outstanding features of the real phenomena.
