STRENGTHENING AND FRACTURE IN FATIGUE - (APPROACHES FOR ACHIEVING HIGH FATIGUE-STRENGTH)

Three approaches to the problem of fatigue resistant materials are reviewed and discussed. The macroparametric approach, the microstructural approach, and a third method which utilizes fundamental deformation characteristics of materials to form a unifying rationale with which to describe fatigue behavior. Examples from the literature are cited to illustrate the degree of success which has been achieved with each approach.
