| Abstract: | Based on the theory of thermal elastic\|plastic stress analysis and the increment theory of finite element,this paper analyzes the residual stress of thin steel pipe with straigth welding line,using the finite element software\|ANSYS.The studying results indicate that the largest tensile stress is at the welded line,and the tensile and compressive stresses arise by turns.The calculated results are in agreement with the experimental measurements,providing reference for the theoretic analysis of residual stress. |
