Abstract: In this paper, a rigid-visco plastic finite element system for simulating forging processes is introduced. The system can deal with two-dimensional forging processes (including the axisymmetric and plane deformation problems) with arbitrarily shaped dies. The function of the system include: the description of die geometries and the generation of die parameters, the generation of initial meshes, the automatic generation of initial velocity field, the treatment of the friction condition on curved contact boundaries, the problems of contact and separation of nodes on/from the dies, the remising technique and close to those of production.
