摘要
The 3-D simulation on the forming process of LDH(Limiting Dome Height)test and a car door inner panel is conducted with the dynamic explicit finite element analysis code LSDYNA3D. The analysis results of LDH test are compared with that of experiments. FLD(Forming Limit Diagram) is used for possible defect detection during the simulation of the car door inner panel, and the distribution of the final thickness and normal strain of sheet metal is studied.
