Non-Zero Mean Stress
We were curious about how mean stress would affect the fatigue life of the gStent-BE standardized test stent so we designed an experiment to [...]
FEA Predicts Fatigue
One major success of the gStent-BE as a standard test stent is the consistent fracture location during axial fatigue loading. All reported fractures occurred [...]
Model Validation Data
I built a Finite Element Model of the gStent-BE and compared the force/displacement response with data from an experiment on my Bose 3220 Dynamic [...]
Stent Dimensions
The generic balloon expandable stent, a.k.a. the gStent-BE, is laser-cut from stainless steel tubing the same as most commercially available stents. It has a [...]
Generic Balloon Expandable Stent
The ASTM F.04.30.06 undertook an inter-laboratory study for axial fatigue testing of a generic, stainless steel balloon expandable stent. We were interested in resolving [...]
Contact Interaction for Medical Implants
There are many circumstances when it is necessary to model contact and contact interactions when analyzing medical implants. Such circumstances arise when devices interact [...]
