A Simulation-Informed Modeling of Depth of Penetration of Rigid Rods Into Quasibrittle Solids

Abstract

The present study proposes a model aimed to provide a rational estimate of the penetration depth of rigid projectiles into quasibrittle solids. Penetration at normal incidence into massive targets, made of materials predisposed to microcracking, is marked by a high level of aleatory variability and epistemic uncertainty. This inherent stochasticity is addressed by the model developed based on the particle dynamics simulations that provide the key modeling ingredient – the estimate of the radial traction required to expand a cylindrical cavity at a prescribed rate.
