modeling nitinol wire in BRACING SYSTEM ???

Hello,
I'm new in this forum and I've a problem that i can't resolve. I need to model nitinol in Abaqus: I've read the documentation (Search for answer ID 1658 UMAT and VUMAT routines for the elastic-plastic simulation of Nitinol 4699 Abaqus/CAE plug-in utility to calibrate Nitinol material behavior) and many topic in Internet but I don't understand if I must use a VUMAT subrutine or it is sufficent the tool of user defined material in Abaqus/CAE. I need something simple like an elastoplatic behaviour with hysteresis given by the different states of austenite and martensite.
please help me
best regard
max

In the constitutive model section, you will find that Ansys has a built-in working super-elastic SMA model (No Shape Memory Effect).
