摘要
We discuss the benchmark strategy to check the accuracy of elastoplastic numerical solutions based on a fully two-dimensional analytical solution. Associated rate-independent non-hardening plasticity with von Mises or Tresca criteria is assumed throughout. Algorithms for integration of the rate equations, strategies for stress updating over a time step, and tangent operators are discussed. The accuracy of a simple incremental algorithm as a function of the time step is discussed.
