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
