Abstract
Modern computational methods and experimental test procedures are being developed to determine more accurately the air-blast loading and dynamic response of naval ship structures subjected to weapon explosions. Previously, a series of air-blast trials on full-scale stiffened panels typical of those used in warship superstructures had been conducted for conventional scale weapons (under 454 kg HE) to evaluate new design and damage-assessment techniques. The present report desribes the experimental results and the associated numerical study of the panel response for a longer duration loading generated by the simulation of a 8 kiloton nuclear weapon surface explosion called MINOR SCALE. The panel, exposed to a side-on overpressure blast loading of 345 kPa peak and 200 ms positive duration, experienced only slight permanent deformation of about 25 mm with no apparent weld or buckling failure.
