Abstract
Residual stresses usually play an important role in partially yielded mechanical parts. In fact, its deleterious effects need to be considered, in machine design, to prevent unexpected mechanical failures. In this paper, it is analyzed the effect of residual stresses in partially yielded beams, with rectangular cross section, submitted to fatigue loading. To accomplish this objective an analytical model is proposed, for estimating both residual stress distribution in partially yielded beams and its respective fatigue life.
