Accurate evaluation of fracture parameters for a surface-cracked tubular T-joint taking welding residual stress into account
Abstract
An efficient numerical analysis procedure based on FEM was implemented for evaluating the effect of welding residual stress (WRS) on mixed-mode stress intensity factors (MM-SIFs) for a non-planar surface-cracked tubular T-joint with a rounded weld toe. A multi-pass welding simulation was carried out using real welding conditions by means of an effective in-house welding simulation code. A fully compatible 3D finite element mesh generation system...
