## Abstract A thermal model based on explicit time integration is developed and implemented into the explicit finite element code DYNA3D to model simultaneous forming and quenching of thinβwalled structures. A staggered approach is used for coupling the thermal and mechanical analysis, wherein each
Laser forming is a thermal process for the deformation of sheet metal by thermal stress. Temperature distribution is the most important factor for determining the bending angle of the sheet metal. In the present study, the combined effect of the temperature of the workpiece, the temperature gradient
