Effects of Notches and Grain Size on Transformations in Nitinol
In this paper, we present a research methodology to characterize the effects of crystallographic orientation and grain size on the deformations and transformations in [...]
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 [...]
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 [...]
Nonzero Mean Fatigue Testing of Nitinol
This paper describes a fatigue test protocol that was used to determine the factor of safety for a superelastic Nitinol implantable medical device. A [...]
Transrenal AAA Stent
One of the very first stent designs I worked on was the transrenal stent for TeraMED’s Ariba bifurcated graft system. This was an early [...]
