At the 2006 SMST Conference in Asilomar Dr. Paul and I had he privilege of sharing our experience of working with Nitinol and particularly FEA of Nitinol during a full day tutorial. It was an honor to have an hour to discuss the ins and outs of modeling Nitinol using FEA.  You can download our presentation of the fundementals of modeling Nitinol using Finite Element Analysis (FEA) including all the details of nonlinear constitutive behavior, contact, boundary conditions, element choices, validation and much more.
