In 1970s,LEVY et al [1]applied plastic deformation theory to the finite element(FE)simulation of sheet metal forming processes and developed one—step inverse approach．In this method,the final part shapes are prescribed and the initial blank sheet configurations are solved,satisfying the external force conditions based on the finite element formulation taking account of deformation theory aswell as static equilibrium condition．The one-step calculation is capable of efficiently handling complicated sheet forming problems and providing that the results are in close agreement with incremental FE predictions．
