Abstract: Metal bulk forming is a large nonlinear deformation process in geometry and physics. This paper reviews
briefly the developmental history of 3D numerical simulation techniques for the metal bulk forming process, then,
prehensively its current research status and priority research areas inland and abroad. Researchers
have turned t heir steps from macro, singleness and decentralization, mon2t ype simulation to micro, coupling
and integration, and specialty2t ype simulation. Four new methods on numerical simulation are presented, which are
meshless method, adaptive FEM met hod, rigid2plastic finite2boundary element method, and feature2based FEM
method. At the end of t he paper, an attempt is made to forecast the future progress of
