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 applying in-plane loads in that if applied too fast, they will cause dynamic, shock effects. It is best to apply them at rates similar to rates used to apply any in-plane loads 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:
It should not be difficult to add to other materials when needed.
