Analytical model for failure of clamped beam subjected to projectile impact

Abstract

In the present study, an analytical model is presented for predicting different deformation modes (mode I–IV) that a rigid-plastic clamped beam may undergo when struck symmetrically by a rigid projectile having a finite width. Herein, the plastic deformation (mode I) of the beam is modeled using three basic phase of motion (phase 1–3) and the material failure (mode II–IV) is predicted using an energy criterion. The derived analytical model is validated via numerical solutions.
