Inherent Strain Analysis of Thin-Walled Structure Welding Deformation

Abstract:

With the rapid development of the automotive industry and sheet metal welding structure widely used in the production practice, study sheet structure welding deformation law and method of controlling the production practice has become increasingly important significance. In this paper, inherent strain finite element method is used for analysis of thin-walled box beam welding deformation. The use of different weld residual plastic strain inherent strain in ANSYS on distributed temperature load can be used to achieve different inherent strain value loaded. Thereafter, the calculation results and the test data are compared and found that this method can improve the calculation accuracy, and therefore have a certain effectiveness.
