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

A procedure for the finite element computation of the limit load of rigid-perfectly plastic solids is presented. The approach is based on the kinematic theorem of limit analysis, which is formulated so as to reduce the problem to the search of the essentially free minimum of a convex, but not everyw

## Abstract A numerical method of the Newton‐Raphson type is presented for elasto‐plastic analysis using the finite element method. The method is developed from Nadai's deformation theory and Hooke's law. Numerical examples are used to show that the method provides very rapid solution convergence.
