摘要：

The paper deals with the evaluation of the effects produced by residual stress fields on fatigue crack propagation. After a short discussion of general phenomenological aspects, the results of fatigue crack growth tests on compact tension specimens containing residual stresses due to welding are summarized. Two numerical methods, i.e. the finite element method and the weight function method, are then applied to model the effects produced by the residual stress field, allowing a detailed analysis of the experimental data to be obtained. © 1990.
