| Abstract: | As a new forming method of stamping for sheet material, drape forming is now more and more used for solid phase forming process of polymer materials. According to the characteristic of high nonlinearity of large strain deformation, thermo-mechanically coupling and boundary friction involved in drape forming process, this paper established static explicit finite element model based on "continuous equilibrium equation", which is suitable for numerical simulation for problem of this type, and performed FEM analysis for drape forming process of fighter plane canopy made of polymer of polycarbonate(PC). |
