From page 141...
... Many material models are available to represent a wide range of material behavior, including elasticity, plasticity, thermal effects, and rate dependence. In addition, DYNA3D has a sophisticated contact interface capability, including frictional sliding and single surface contact, to handle a range of mechanical interactions between independent bodies.

From page 142...
... A plastic volumetric strain versus pressure curve can be obtained from the total volumetric strain curve by subtracting the elastic strains X D W Xv p = − − +1 1 0ln( )  from the latter.
