Metal fatigue is an everyday problem. It has been brought to the attention of the general public by frontpage newspaper stories. Textbook writers commonly choose the very homliest of examples to introduce the topic (1). Fracture of metals under cyclic loading at ordinary temperatures remains, after over a hundred years (2) of intense study, probably the major single materials problem in fracture-safe design. The fracture of metals at high temperatures has been studied for a rather shorter time (3) and certainly less intensely. It is a complex problem, and materials engineering has by no means perfected useful high-temperature fracture criteria even for uniaxial loading under monotonic conditions.
