Paper Title:
Numerical Simulation of Blast Mitigation Cladding with Gradient Metallic Foam Core
  Abstract

In the present study, numerical simulation is performed by using the commercial software ANSYS/LS-DYNA to investigate the various effects on crushing stress and energy absorption capacity of the blast mitigation cladding with gradient density aluminium foam in irregular manners, a 2D Voronoi technique is employed to generate the stochastic gradient metallic foam core. Results show that a properly designed energy absorption foam cladding with graded density is able to absorb high blast energy while with a lower force transferred to the substrate or the protected structure. Parametric study with respect to impact velocity and density gradient indicates that the density gradient foam cladding is effective in increasing energy absorption capacity especially under high velocity blast load.
