Abstract: A good knowledge of the welding residual stress field and the corresponding distortion is needed when the interaction between manufacturing stresses and future (mechanical and/or thermal) design ...

Abstract: The reduction of welding stresses during some standard post-weld heat treatments (PWHT) is numerically determined for a multi-pass butt-welded pipe made of a micro-alloyed C-Mn steel. Most of ...

Abstract: Stress redistributions during local Post Weld Heat Treatments (PWHT) are numerically studied for a multi-pass butt-welded pipe with mechanically unrestrained ends. The pipe material is a micro-alloyed ...

Abstract: The redistribution of calculated welding stresses during different post weld heat treatments (PWHT) is numerically investigated for a girth-butt welded thin-walled pipe made of a micro-alloyed ...

Abstract: Stress redistribution in a butt-welded pipe during later mechanical and thermal treatments is studied numerically by use of a thermoelastoplastic FE-model. It is proposed that the influence of ...

Abstract: This paper describes a study of the multi-pass butt-welding of thick-walled pipes. Two different groove shapes were used: single-U and narrow-gap grooves. Strains were measured on both the pipe ...

Abstract: Temperatures, stresses, and deformations in a single-pass butt-welded pipe are studied with a full three-dimensional finite element model. The model covers the whole circumference and the complete ...

Abstract: A kinematic hardening model including an associated flow rule is proposed for elastoplastic deformations in graphitic grey cast iron. Quantitatively good results are obtained when comparing with ...

Abstract: A fast and simple method for the determination of the residual deformation for a class of welding problems, ring-stiffened pipes, is proposed. The method can predictradial as well as angular ...
