A second-order cell-centered Lagrangian scheme with a HLLC Riemann solver of elastic and plastic waves for two-dimensional elastic-plastic flows

In this paper, we propose a fast and efficient second-order cell-centered Lagrangian scheme for 2D elastic-plastic flows with the hypo-elastic constitutive model and von Mises' yielding condition. First, we develop a novel HLLC-type Riemann solver with elastic and plastic waves (HLLCEP) for 2D elastic-plastic flows. Then, we present a two-directional momentum conservative method to determine the moving speed of grid vertexes. Moreover, we...
