Fatigue Crack Initiation
The image on the left is a time lapse animation of a crack initiating and growing from a notch in super-elastic nitinol. It is [...]
Computational Modeling of Cardiovascular Devices
I was given the opportunity to discuss the State-of-the-Art Computational Modeling for Cardiovascular Devices at the FDA/NHLBI/NSF Workshop at the FDA White Oaks campus [...]
High Speed Testing of Medical Devices and Materials
An important input to FEA is material characterization and limit information. In our laboratory we use a Bose 3230 test system for achieving test [...]
The Selection of Nitinol Material Models for FEA Simulations
Nitinol is a unique metallic alloy that is ideally suited to use in medical devices. It has excellent biocompatibility and most of all it [...]
