Abstract

Abstract

The blast mitigation behavior of a density-graded cellular sacrificial cladding is investigated by using a nonlinear plastic shock model and a cell-based finite element model. Based on a rate-independent, rigid-plastic hardening idealization, a theoretical approach is applied to analyze the propagation of shock wave in density-graded cellular rods subjected to blast loading. The influences of the intensity of blast load, the cover mass and the density gradient parameter of the cellular material on the critical thickness, which is the minimum thickness of the core layer when the energy of explosion is fully absorbed, are investigated. A design guide of density-gradient is provided which considers the critical thickness of the cellular core as well as the peak stress at the support end. The validity of the anti-blast analysis of the graded cellular sacrificial cladding based on the nonlinear plastic shock model is verified by using cell-based finite element models.
