Full-Field Measurement of Strain and Transformation in Nitinol
Phase shifted moire interferometry is used to measure full-field strain during uniaxial tension and four point bend loading of nitinol test samples. Differences between [...]
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 [...]
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 [...]
