Spherical vessels made by using the integral hydro-bulge forming technology have been widely used since the invention of the technology,it has been put into production.Therefore the computer simulation of the forming process and the computer aided design are needed.A PC version FEM system is stated in this paper specially for the analysis of forming spherical vessels.The main program is elastoplastic nonlinear FEM program,and the pre-processors and post-processors are developed.The programming for the pre-processors and post-processors is also described in this paper.
