Abstract:

A combined experimental and theoretical study of the response of clamped rolled homogenous steel armor RHA plates to close-in blast loading was conducted. The study covered a range of nominal armor thicknesses of 316 inches 4.76 mm to 34 inches 19.05 mm and nominal charge weights of two pounds 0.91 kg to eight pounds 3.63 kg. Experimental data of vertical deflections and hole areas were used to derive a set of formulae which give a measure of the response of the RHA plates to close-in blast loading. The functional forms used were arrived at through similitude theory and dimensional analysis. A formula was also derived to describe the inception of material failure. The derived set of formulae provide a quick response predictions of damage to RHA plates for system vulnerability or survivability evaluation. Author
