The through-thickness crack propagation and damage evolution in plugging type failure behavior of metallic targets are simulated via the pseudo-spring based smooth particle hydrodynamics (SPH). The damage is computed using the strength of the pseudo-spring system that connects particles to their immediate neighbors. The interactions among particles are defined by the state of these springs having properties guided by material constitutive model of the target. The coupled thermo-mechanical Johnson-Cook model is employed here to account for plastic flow influenced by localized heat generation. The numerical simulation of plugging failure using this computational framework has been presented via examples and validated with experimental and numerical data available in literature.
