TL;DR: In this paper, a method for predicting fatigue crack propagation in welded stiffened panels accounting for the effects of residual stresses is presented, where the effect of welding residual stresses on the crack propagation rate is taken into account by replacing the nominal stress ratio R in the power laws by the effective stress intensity factor ratio R eff.

TL;DR: In this article, the influence of welding residual stresses in stiffened panels on effective stress intensity factor (SIF) values and fatigue crack growth rate was studied using molecular dynamics simulations and a Tanaka-Mura approach.

TL;DR: In this paper, the initiation of a short crack and subsequent growth of the long crack in a type of carbon steel under cyclic loading, concluded with the estimation of the complete lifetime represented by the Wohler (S-N) curve.

TL;DR: In this article, the influence of welding residual stresses in stiffened panels on effective stress intensity factor (SIF) values and fatigue crack growth rate was studied using molecular dynamics simulations and a Tanaka-Mura approach.

TL;DR: In this article, rotating bending fatigue tests were performed on uncoated specimens and specimens coated with diamond-like carbon (DLC) in air environment, and the total stress was evaluated by the superposition of the bending stress calculated by the finite element method and the residual stress induced by the coating deposition.
