Residual stresses and deformations in a welded thin-walled pipe
1989 (English)In: Weld residual stresses and plastic deformation: papers / [ed] E. Rybicki; M. Shiratori, New York: American Society of Mechanical Engineers , 1989Conference paper (Refereed)
Deformations and stresses during butt-welding of a pipe are calculated as well as the residual deformations and stresses. The temperature field during welding is calculated using an analytical solution. The deformations and stresses are calculated by use of the finite element method. A thermo-elastoplastic material model is used. Special attention is paid to the influence of the volume changes due to phase transformations on the deformations (radial shrinkage) and the residual stresses. The calculated radial shrinkage and residual stresses are compared to experimental values. Good agreement was obtained.
