Abstract
A method is described for the incremental elastic-plastic analysis of two-dimensional stress systems (plane stress, plane strain and axisymmetrically loaded body of revolution). The procedure is based upon the finite element method of stress analysis and uniformly stressed triangular elements are used. The derivation of the incremental stress-strain relationship from the Prandtl-Reuss equations and the Von Mises yield criterion is presented. Numerical examples are presented and are compared with experimental and theoretical results in the literature.
