A computational method based on the membrane theory for the analysis of axisymmetric sheet metal forming processes such as punch stretching, deep drawing and hydroforming is presented. The elastic-plastic finite element approach is based on the flow rule associated with Hill's quadratic yield criter
For the finite element analysis of metal forming processes, a method based on the equilibrium of nodal forces is proposed by assuming the deforming metal to be a slightly compressible rigid-plastic material. As an extension of the method, a formulation for finite deformation is derived on the basis
