Abstract

Residual stresses remain in manufactured mechanical components after the forces related to the manufacturing process have been removed. Beneficial compressive residual stresses can be induced using shot peening, cold expansion of holes, and low plasticity burnishing, for example. The purpose of this review is to determine the relevant phenomena and fatigue assessment methodology of the residual stress state. It is shown that the common strategy for fatigue assessment — considering residual stresses simply as mean stresses — may lead to non-conservative predictions. Generalization of the presented methodologies is paid attention to and prospective research areas are indicated.
