Abstract

This paper presents a model for the prediction of the residual stress distribution during fatigue loading. A finite element software is used for taking the cyclic plasticity into account. With this approach, the treatment of the local plastic yield conditions can easily be made from simple purely elastic analysis. The computed values of relaxed residual stress distributions were compared with experimental results obtained by X-RAY diffraction measurements. The stabilised residual stresses calculated after fatigue testing were introduced in a multiaxial fatigue criterion for life prediction.
