Numerical simulation of damage effect for runway subjected to explosive loading

Abstract

Abstract In order to study the blast damage effect of kinetic energy warhead. It is concerned with use the hydro code AUTODYN for the simulation of explosive loading interactions to multilayer runway. A study is presented including an investigation of the effect of blasting depth, layer of runway, boundary of target. Comparisons and analysis are made with crater size, crunch area radius, damage area and the peak pressure. Based on this analysis Based on the theoretical analysis and numerical simulation results, Preliminary rule between explosive effect and influence parameter is obtained. The simulated results have reference value for the design of the penetrator and damage evaluation.
