Experimental Study Regarding Transferred Impulse Mitigation by Perlite Layer
Nowadays the improvised explosive device (IED) threat becomes the most favorite weapon of insurgents in their combat actions and represents the most important aspect in the future generations design of military vehicles. This paper presents an experimental study upon a scale structure regarding the advantages of using a multi-layer structure, metallic material (steel) - granular material (perlite), in mitigation of the explosion effects on a structure representing the vehicle floor. The quantitative and qualitative changes on the behavior of a plane plate subjected to the action of a shock wave, by adding a layer of granular material – perlite, is analyzed, and the occurrence of impulse mitigation is demonstrated and measured.
