摘 要：We introduce a second-order cell-centered Lagrangian scheme for two-dimensional elastic-plastic problems with the hypo-elastic constitutive model and the yon Mises yield *** this paper,we analyze the wave structure of the Riemann problem for elastic-plastic materials and then develop a four-rarefaction-wave Riemann solver with elastic and plastic
