TL;DR: In this article, the authors provide an overview on the current state of fracture mechanics application to weldments and discuss the specific features which any fracture mechanics analysis of weldments has to take into account.

TL;DR: In this article, the surface residual stresses at the weld toe are investigated before and after different loading conditions and for different steel grades, and the results of fatigue tests for butt welds and longitudinal stiffeners improved by high frequency hammer peening are presented.

TL;DR: The grade of restraint is defined as the ratio between the heated zones and the apparent colder material and is not primarily depending on the size of a component as discussed by the authors, but rather depends on the ratio of the heated zone to the apparent cold material.

TL;DR: In this article, the authors provide an overview on the issue mainly from the point of view of the application of fracture mechanics to the determination of the fatigue strength as the topic of this special issue.

TL;DR: In this paper, a series of numerical simulations were performed to examine the variability in welding residual stresses (WRS) for different material models, and the mixed hardening model provided the more accurate prediction of WRS.
