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 [...]
Computing Alternating and Mean Stresses During Fatigue for a Cardiovascular Stent
Finite Element Analysis (FEA) is routinely used to perform fatigue analyses of cardiovascular stents. For the case of balloon expandable stents, this means modeling [...]

ASTM Axial Fatigue of Stent
This work is related to an ASTM F04.30.06 subcommittee activity to develop a standard based on the Fatigue to Fracture methodology. The idea of [...]
Thermoelastic Transformation Behavior of Nitinol
The transformation behavior of Nitinol under uniaxial tension and four-point bending was investigated. A novel sample geometry produced from drawn tubing was used to [...]
ASTM Stent Radial Force Characterization
