| Abstract: | Q235 steel is widely used in construction machinery welding components,vertical weld accounted for most of the welding components.Thermal-structural coupling technology in finite element analysis has been good application.Life-death element technique was applied together in the numerical simulation of temperature and stress fields on Q235 steel vertical weld.Residual stress was by the blindness hole measuring.The results of simulation with that of test were compared.The transverse stress and longitudinal stress were obtained.The numerical results of residual stress distribution are almost consistent with the experimental ones. |
