View source for Generalized Plane Stress and Strain

== Introduction ==

These methods extend [[Analysis Command|Plane Stress MPM]] to allow non-zero stress in the ''z'' direction and extend [[Analysis Command|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:

* [[Isotropic Material|Isotropic]]

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