## Abstract A numerical method of the NewtonโRaphson type is presented for elastoโplastic 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.
This article advocates a general procedure for the numerical investigation of pseudo-rigid bodies. The equations of motion for pseudo-rigid bodies are shown to be mathematically equivalent to those corresponding to certain constant-strain รฟnite element approximations for general deformable continua.
