To explore geometrical shape, stress distribution, strain distribution and wall thickness of product in the process of polycarbonate hot gas bulge forming, numerical simulation of 4mm PC double curvature and large-area workpiece with the chord 1050mm has been conducted by the finite element software DYNAFORM. The results indicate that the deformation of large-area workpiece starts from blank holder to sheet center, and the maximum latitudinal stress and longitudinal stress is located in the center of PC sheet. The maximum reducing rate is approximate to 6.4%. The experimental results fit well with the numerical simulation.
