## Abstract Coronary stents have to sustain up to 700 million cycles induced by the cyclic diameter change of coronary arteries. Therefore fatigue tests are required to allow an accreditation or commercial utilization. In the present study coronary stents were investigated after cyclic fatigue in a
A rolling contact fatigue life model encompassing crack initiation life and crack propagation life was developed in Part 1 of two companion papers. This paper concerns the experimental verification of the developed life model. The specimens were machined by using various machining conditions and at
