✦ Synopsis

Analyses are made for predicting fatigue limit of notches with and without the effect of compressive residual stresses. The residual stresses are introduced by shot peening or surface rolling, and detected by X-ray diffraction technique. The theoretical work is based on the local stress method and focused on an asymmetrical stress condition at the notch root. Fatigue tests are carried out, and an agreement is reached between predicted and tested data.

Hardened parts are used to minimize abrasion at contact surfaces and to extend the lifetime of machine components. Different risks to failure, and therefore, different fatigue limits result from imperfections, notches and surface properties. Two methods for calculating fatigue limits of surface-hard
