Abstract
We present a front tracking approach for the numerical simulation of one‐dimensional elastic‐plastic flow in solids with cavitation. The algorithm uses a simplified model system where the behavior of the materials is modeled by a barotropic equation of state for the hydrostatic pressure, the Hooke’s law for the deviatoric stress, and the von Mises condition for the elastic‐plastic phase change. To characterize the cavitation in the solution state, a simple cut‐off criterion is employed. Sample numerical results are shown to validate the proposed front‐tracking method.
