Numerical Simulation of Residual Stress of Butt Welding Pipe Based on Element Birth and Death
Residual stress of butt weld pipe was simulated based on the ANSYS.3D element method was used in the model.Temperature depended material properties was considered as well as the effects of the environmental conditions on convention and radiation.The method of element birth and death was applied to simulate the model of loading welding heat source.The distribution regulation of residual stress field were obtained,and the results were analyzed and discussed.
