Fatigue-to-Fracture Symposium
Many thanks to the organizers of the recent Fourth Symposium on Fatigue and Fracture of Metallic Medical Materials and Devices and especially to Brian Berg for shepherding the new ASTM F3211 Standard Guide for Fatigue-to-Fracture (FtF) Methodology for Cardiovascular Medical Devices into existence.
The Fatigue-to-Fracture Symposium showcased some great examples of how companies have implemented FtF concepts.
We presented an approach for obtaining limit data using an engineered test specimen called the teStent™. The teStent stent is an example of a surrogate test specimen. Following our approach, the teStent stent can be used to characterize the fatigue properties of medical implant materials in terms of stress (or strain) and is an excellent way to increase confidence in your finite element predictions.
Our paper will be published in ASTM STP 1616, but please contact us to learn more about how you can benefit from using surrogate test specimens and a Fatigue-to-Fracture approach to medical device design validation.
