TL;DR: Differential stress-strain relationships are used to generate a system of simultaneous firstorder differential force-displacement equations which are integrated numerically to obtain the stresses, strains, and displacements in inelastic structures.
Abstract: Differential stress-strain relationships are used to generate a system of simultaneous firstorder differential force-displacement equations which are integrated numerically to obtain the stresses, strains, and displacements in inelastic structures. For the biaxially stressed element, the concept of isotropic hardening and a generalized stress are used to evaluate an effective modulus and Poisson's ratio, which vary continuously from their initial values during elastic straining action to their asymptotic values during intense plastic straining action. The surface of plasticity for this element closely approximates the von Mises surface when the generalized stress is set equal to the von Mises stress and the strain distribution is essentially identical to that obtained by the Prandtl-Reuss incremental flow theory. The analysis of the MIT shear lag structure is presented to demonstrate the applicability of the method to systems of practical size and interest.

TL;DR: In this article, the particular yield conditions of von Mises and Tresca are considered in detail for wire drawing and the method of solution for a general yield criterion is described.
Abstract: T he flow of a plastic-rigid material forced through a rigid conical-shaped channel or die is considered. The method of solution is described for a general yield criterion. The particular yield conditions of von Mises and Tresca are considered in detail. Application of the theory is made to wire drawing.
