Evaluation of the Effect of an Explosive Charge Closed to a Steel Structure Plate

Abstract

The effect of an explosive charge closed to a structure plate is a strong loading for a ship. To be able to quantify the damage bred on a structure, we made any tests with a charge closed to a metallic plate. From experimental results, we elaborated an analytical model supposing a constant velocity for plastic hinge movement. From the Gurney’s relation which we modified, we are able to determinate the initial velocity transmitted to the structure plate and to estimate the gas mass flowing to the downward step after the charge detonation.
