Material Behaviors

This entity defines additional material features coupled to the referenced material, like: Failure, Permeability, Porosity, Thermal, Fatigue, Cohesive, Inelasticity, and so on.

Material Behaviors are referenced in the Material Entity Editor, which allows for a complete view of the material definition.

Restriction: This entity is inly supported in the LS-DYNA profile.
