摘要: In this paper, an improved inner point stress integral formulation for 2-D or 3-D elastoplastic problems is given by Stokes' theorem. formulation, Cauchy principal integrals appearing in the usual are converted into weakly singular and a line over potential plastic area as well corresponding free term. Numerical examples problem show that correct.
