A multi-material HLLC Riemann solver with both elastic and plastic waves for 1D elastic-plastic flows

A multi-material HLLC-type approximate Riemann solver with both elastic and plastic waves (MHLLCEP) is constructed for 1D elastic-plastic flows with the hypo-elastic model and the von Mises yielding condition. Although Cheng in 2016 [1] introduced a HLLC Riemann solver with elastic waves (HLLCE) for 1D elastic-plastic flows, Cheng assumed that pressure is continuous across a contact wave. This assumption may lead to numerical errors, especially...
