Abstract

This paper presents a study on blast wave propagation in a soil structure when subjected to a surface air blast loading. The experimental work utilized the use of plastic explosive of 1 kg weight (PE4) in order to create a spherical blast wave at a fixed standoff distance. The experimental results were then compared with the numerical simulation model computed using LSDYNA3D. Although the computed simulation and experimental results showed large difference in terms of values, but both results provide a similar trend in terms of blast peak overpressure.

Abstract

This paper presents the experimental and numerical investigation of angled shape metal plates response when subjected to an air blast loading. V shaped plates were fabricated at angles of 90o, 120o and 150o respectively. The charge weight of 1 kg (PE4) was used to create a spherical blast wave at several standoff configurations. The experimental results were then compared with the numerical simulation model computed using LSDYNA3D.
