Shape Memory Alloy
The Shape Memory Alloy feature is used to model stress-strain relationships which are nonlinear even at infinitesimal strains. This material model requires the Nonlinear Structural Materials Module.
By adding the following subnodes to the Shape Memory Alloy node you can incorporate other effects:
•
Thermal Expansion (for Shape Memory Alloy)
•
Initial Stress and Strain
•
External Stress
Note: Some options are only available with certain COMSOL products (see https://www.comsol.com/products/specifications/)
The settings for this feature are documented in the section Shape Memory Alloy in the Solid Mechanics chapter. See also the section Shape Memory Alloy in the Structural Mechanics Theory chapter.
