Fatigue at High Temperature.
Abstract
The report was prepared as the keynote address to be given at the 1972 Symposium on Fatigue at Elevated Temperature at the University of Connecticut, June 18-23, 1972. It describes the high-temperature fatigue problem as a failure process in a notch in some structure involving nucleation and early growth at the notch root, high strain crack propagation through the plastic zone of the notch, and elastic crack growth to ultimate failure. Particular attention is given to a description of the high-temperature phenomenology, distinctions between high- and low-cycle fatigue effects at high temperature, and methods for treating notches.
