Generalized Plane Stress and Strain

Introduction

These methods extend Plane Stress MPM to allow non-zero stress in the z direction and extend Plane Strain MPM strain to allow non-zero strain in the z direction. Currently, the only way to set the z direction stress or strain is to use a PropertyRamp Custom Task. Applying out-of-plane loading in these generalized methods is similar to apply in-plane loads in that if applied to fast, they will cause dynamic, shock effect. It is best to apply them are rates similar to those used to apply the in-plane loades in a simulation.

Material Support

These generalized 2D methods are in early development and not implement for all materials. The only materials that current model generalized plane stress or plane strain are:

• Isotropic

It should not be difficult to add to other materials when needed.
