Residual stress study of welded high strength steel thin-walled plate-to-plate joints part 2: Numerical modeling
Abstract In the Part 2 of the current study, a sequentially coupled thermal-stress analysis is conducted to model the welding process and the final residual stress distribution of the RQT701 high strength steel thin-walled plate-to-plate welded joints. The accuracy and reliability of the numerical modeling is validated by comparing with the test results. After validating the accuracy of the modeling procedure, a small scale parametric study is carried out to investigate the influences of some key welding parameters on the magnitude and distribution of residual stress.
Highlights ► The welding process of high strength steel plate-to-plate welded joints is studied. ► The welding process is modeled by a sequentially coupled thermal-stress analysis. ► The residual stress distribution is studied by using numerical modeling. ► Accuracy of the numerical model is validated by comparing with test results. ► A parametric study is carried out to investigate the effect of key welding parameters.
