... were employed to predict the fatigue crack growth rate. Results indicate that the depth and width of the weld pool is increased with the increase of the welding current. The effect of the residual stress on the fatigue crack growth rate becomes more obvious when the stress ratio is decreased...

... ABSTRACT To accurately predict the stress state of hull stiffened plate structure after induction heating process, the intelligent algorithm of support vector machine (SVM) was studied to predict the residual stress distribution of stiffened plate structure after induction heating. Firstly...

... ABSTRACT This study proposes a numerical simulation system for the high-frequency mechanical impact (HFMI) treatment that can consider the welding residual stresses (RS). The validity of the HFMI simulation process is examined by a HFMI-treated flat plate. Then, the effectiveness...

... Stress concentration and tensile residual stress are detrimental to fatigue life of welded joints. In order to reduce stress concentration, a mathematical design method of tensile triangles (MTT) based on bionics was applied to weld shape design. Accordingly, the stress concentration...

... under all operational load cases. Moreover, the results suggest that the EF assembly procedure and the FAT test need to be indeed considered, as they yield significant residual stresses on the tensile armour wires inside the EF. INTRODUCTION A Flexible pipe is a composite construction of multiple...

... that this is a viable strategy. One of the issues considered as a key threat to pipeline integrity is corrosion. Therefore, understanding the distribution and redistribution of residual stresses within a pipeline affected by corrosion can be of great benefit. A way to monitor in-situ the pipeline residual stress...

... of the diameter and thickness in the circumferential direction. Bastola et al. (2014) confirmed that collapse strength was reduced by residual stresses, and the residual stresses in the circumferential direction had more significant effect than the residual stresses in the longitudinal direction. Influence...

... distortion of both analyses. Furthermore, different plate orientations are taken into account. INTRODUCTION Welding process is one of the most popular assembly method used by many industries such as ships and bridges. However, welding produces many unavoidable problems such as welding residual stress...

... ABSTRACT Residual stresses and deformations that generated by pipe forming and pipe welding act as harmful factors causing deformation, buckling, and fatigue behavior of a pipe. In this paper, the effect of residual stresses and deformations due to three roll bending and butt-welding...
