Abstract
This study presents the effect of transformation induced volume strain on the thermo-elastoplastic model in the simulation of Nd: YAG laser welding process applied for thin sheet metal dual phases steel DP600. The metallurgical phase transformations during heating and during cooling are used as the thermal expansion dependent parameters. The effect of transformation induced volumetric strain was identified where the comparisons of the elastoplastic model with and without metallurgical effect are based on the global distribution of residual stresses such as the longitudinal residual stresses and the transverse residual stresses.
