Abstract

Considering the applications of cellular materials in the sacrificial claddings for impact/blast alleviation, this study presents a method for the design of cellular foam claddings with temperature gradient under high initial velocity impacts. A one-dimensional model for the compaction of cellular foam claddings with temperature gradient is developed for the striker-rod impact scenario based on the R-P-P-L idealization. The predictions of the proposed model are compared with FE simulations with the realistic R-PLH material model based on the actual experimentally derived stress-strain curves. The predictions of the dependency of critical length, critical impact velocity and impact force of the cellular foam rod with temperature gradient on the temperature distribution and the relation of critical impact velocity of an aluminum foam rod with a given length to the temperature contrast at its two ends are compared well with the numerical simulations results.
