FEA of In-Vitro Test Methods for Radial Force Characterization
An overview of the typical in-vitro test methods used to characterize the performance of Nitinol stents is presented. Characterization requires a consistent definition and [...]
FEA and Nitinol: Beyond the Fundamentals
At the 2006 SMST Conference in Asilomar Dr. Paul and I had he privilege of sharing our experience of working with Nitinol and particularly [...]
