On development of methods of computer simulation for processes of metal forming

The comparative analysis of the main modern methods of the solution of metal forming boundary value problems is executed. The brief retrospective review of development of methods of the solution of metal forming boundary value problems (including methods of computer simulation) is made. The new method of computer simulation of metal forming processes. It is a method of linearization of nonlinear problems and is based on the variation of a finite element method. The outcomes of computer simulation of the upsetting process of stuffs with different flow characteristics is presented. The offered method and its modifications allow considerably to reduce time of the solution of boundary value problems, providing sufficient veracity of outcomes.
