Material

All elements have an associated property of the appropriate material type.

•     Isotropic Materials:

•    Has the same quality on direction

•    Is used universally

•     Orthotropic Materials:

•    Has different quality about two orthogonal directions of shell plane

•    Is used to paper, film etc.

•     Anisotropic Materials:

•    User-defined 3x3 matrix is used for constitutive equation

•    Is used to materials which have different properties in different directions.

•     Hyperelastic Materials:

•    Rubber or rubber-like materials

•    Initially isotropic

•    Nonlinear

•    Uses a large strain measure

•    All strain energy is recoverable

•     Plastic Materials:

•    J2 (von Mises) plasticity material formulation

•    Rate independent plasticity

•    Appropriate for metal plasticity
