An HLLC-type approximate Riemann solver for two-dimensional elastic-perfectly plastic model
Journal of Computational Physics(2022)
摘要
•Characteristic analyses are performed for elastic and plastic phases respectively.•The order of stress waves of an augmented one–dimensional problem is researched.•A new multi-wave HLLC-type approximate Riemann solver is proposed.•The solver includes almost all elastic, plastic and shear waves simultaneously.•A cell-centered Lagrangian method with the HLLC-type Riemann solver is developed.
