Reply To: How can I enter a new Superelastic model for the presence of R-phase in Nitinol?

[John Doyle]

Ansys does not have a standard material option that will simulate the rhombohedral distortion (R-Phase) of SMA martensitic structures.  If this effect is critically important and you cannot calibrate the standard SMA properties to sufficiently match your test results, you would need to program your own material model via USERMAT routine.  For more details, please refer to the MAPDL  Programmer's Reference (ansys.com)
