Accuracy and Stability of the numerical approximation for the integration of elastoplastic constitutive relation are presented. For the sake of argument, the linear elastic perfectly plastic model with a von Mises yield surface and associated flow rule is used throughout. A variant of the linear α-method for the numerical integration of the elastoplastic constitutive relation is presented and the performance of which is assessed through comparison with the analytical solution of the landmark paper by (Krieg and Krieg, 1977).
