Finite element formulation based on Updated Lagrangian method was employed to simulate the forming process of aircraft canopy made of polycarbonate plate. Shape and thickness distribution of the blank sheet at the end of forming stage was performed. This agrees with actual product’s thickness distribution tendency.
