Residual Stress And Deformation

This paper investigates and determines residual stress and deformation of butt welded joint between two plates of low carbon steel and stainless steel. Based on the theoretical basis of the virtual force method [1-3], this study has constructed the formulas to calculate the residual stress and deformation in fusion welding of two dissimilar materials for butt joint and single-pass weld. The residual stresses and deformations in the butt-welded joint of two plates of 5 mm thickness, beveled edge, single-pass weld between low carbon steel and stainless steel are determined and compared to show the difference of residual stress and deformation in each plate. These results are also compared with the butt welded joint of two low carbon steel plates.

Good Agreement

A numerical simulation system, which integrated FDM (Finite Difference Method) and FEM (Finite Element Method) and coupled temperature field and stress field, was established. This system was then validated by simulation of a stress frame casting. The calculated results are satisfactory and in good agreement with the theoretical analysis. As a practical application, a wave-guide casting was simulated. The stress evolution during casting solidification, residual stress and deformation are predicted.

Residual Stress And Deformation

The shot peening process is largely used for the surface treatment and forming. The residual stress distribution developed within material may induce distortion of the component. The residual stress formed during the shot peening process is simulated numerically. The elastic-plastic constitutive model is adopted to describe the plastic behavior of the target material. The influence of shot peen speed on residual stress and deformation distribution is discussed.
