Abstract
Finite element (FE) simulation is the powerful tool for an analysis to thermo-mechanical coupling process and helps the manufacturer in understanding the effect of the various parameters in the hot stamping process better. The simulation results are strongly dependent on the accuracy of boundary condition. In this paper, the heat boundary condition is firstly obtained based on an inverse analysis method. The characteristics of heat transfer in the interface between the sheet and the die was also analyzed. Then, the numerical simulation to the whole hot stamping process was made with simulation software by applying the identified heat boundary condition. The good agreement between the calculated and experimental temperatures demonstrates that the inverse analysis method is a feasible and effective tool for identifying the sheet-die heat boundary condition.
