Residual stress effects on fatigue life of welded structures using LEFM
Zuheir Barsoum,Imad Barsoum +1 more
TL;DR: In this article, a welding simulation procedure is developed using the FE software ANSYS in order to predict residual stresses and their relaxation during crack propagation by isoparametric stress mapping between meshes without and with cracks.

Effect of cold expansion on fatigue performance of open holes
TL;DR: In this article, residual stress measurements were made on aluminium alloy 2A12T4 open holes after cold expansion and a finite element method (FEM) was also used to analyze the residual stress distribution around cold expansion hole.

Investigation on fatigue performance of cold expansion holes of 6061-T6 aluminum alloy
TL;DR: In this article, the effect of cold expansion on the fatigue behavior of fasten holes of AA6016-T6 was investigated and it was found that the fatigue crack has bypassed the tri-directional compressive stress domain in all the fracture surfaces of the CE specimens, which was believed to be beneficial to the fatigue life prolongation.

Stress-intensity factor equations for cracks in three-dimensional finite bodies
James C. Newman,Ivatury S. Raju +1 more
TL;DR: In this paper, the stress intensity factors used to develop the equations were obtained from three dimensional finite element analyses of these crack configurations, where the plates were subjected to remote tensile loading.

Fracture mechanics analysis of a crack in a residual stress field
TL;DR: In this article, a path independent J integral for a crack in a residual stress field is obtained and the modified J is equivalent to the stress intensity factor, K, under small scale yielding conditions and provides the intensity of the near crack tip stresses under elastic-plastic conditions.

The Bauschinger and Hardening Effect on Residual Stresses in an Autofrettaged Thick-Walled Cylinder
TL;DR: In this paper, a new theoretical model for a high strength steel is proposed and a closed-form solution for calculating residual stresses in autofrettaged tubes has been obtained, showing that the influence of the combined Bauschinger and hardening effects on the residual stress distribution is significant.
