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 [...]
Phase Transformations in Nitinol
Nitinol is well suited to the design constraints imposed by medical device applications, however, only modest progress has so far been made regarding long [...]
Reliability Assessment of Superelastic Medical Devices
A series of phase shifted moire interferograms showing a NiTi dogbone experiencing increased tensile loading. The two images on the right exhibit clear [...]
FEA and Experimental Evaluation of Superelastic Stent
The mechanical properties of Nitinol stents are normally evaluated experimentally due to complexities resulting from large deformations and material nonlinearity. Despite difficulties associated with [...]
Simulating Radiofrequency Ablation
I became interested in simulating the effects of RF ablation as early as 1998 when I did some work for St. Jude Medical. What [...]
Modeling Polycrystaline Nitinol
There are many ways to model Nitinol using Finite Element Analysis. Over the years we have studied them all, from rigorous analytical implementations based [...]
