Nonlinear Structural Material Module
The Nonlinear Structural Materials Module supplements the mechanical capabilities of the Structural Mechanics and MEMS Modules by adding nonlinear material models. When structural deformations become large, certain nonlinearities in the material properties force the user to abandon linear material models. This situation also occurs in some operating conditions, such as high temperatures.
The Nonlinear Structural Materials Module adds elastoplastic, viscoplastic, creep, and hyperelastic material models. User-defined material models based on strain-invariants, flow rules, and creep laws can easily be created directly in the user interface with the built-in constitutive laws as a starting point.
