Crack initiation mechanisms during very high cycle fatigue of Ni-based single crystal superalloys at high temperature

, 2020
Crack initiation mechanisms in the very high cycle fatigue (VHCF) regime of nickel-based single-crystal (SX) superalloys have been investigated at high temperature (1000 °C) and under fully reversed conditions (R = −1). For all Ni-based SX alloys tested,

On high-cycle fatigue of 316L stents

Computer Methods in Biomechanics and Biomedical Engineering, 2012
This paper deals with fatigue life prediction of 316L stainless steel cardiac stents. Stents are biomedical devices used to reopen narrowed vessels. Fatigue life is dominated by the cyclic loading due to the systolic and diastolic pressure and the design against premature mechanical failure is of extreme importance.
