You can perform a transient Structural-thermal Multiphysics simulation in ANSYS mechanical to see the effect of cryogenic temperature on your material. However you need to define temperature dependent material first (If there is published data available for this material of course). If this is something you want to do. Ask me to provide more info for performing a Multiphysics simulation for you.

Thank you for your response. I am thinking about the same. But the for that do I have to create a custom material for liquid nitrogen.? If there is some kind of chemical reaction going on between nitinol & liquid nitrogen, can these factor modify the result I will get from the transient structural thermal? Or the phenomena from the chemical reaction will also be transferred to the test specimen in case of simulation?

you can simulate this project by solidworks software(cosmos works)
