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 3/16 inches (4.76 mm) to 3/4 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)
