I'm kinda new to FEMAP but I already learned the basics. So I'm doing research for my master thesis where I have to study Shape Memory Alloys, focusing Nitinol (for stent application) and I am using FEMAP to do all the numerical simulations. I recently discovered that in the materials section there are two different ways to apply Nitinol. Either I go with de solution 508. NX Nastran Shape Memory Alloy or I go with 605.NEi Nastran Nitinol.
What I wanted to know is what material models (in terms of material behavior) are behind this solutions and/or what parameters do I need to provide to FEMAP in order to get these working.
