Abstract : The application of X-radiation as a lethal mechanism or decoy discrimination technique is studied theoretically. Volume 1(Secret) applies the studies of this volume to vulnerability analysis of the MARK 4 re-entry vehicles and decoys. This volume presents the unclassified studies of the dynamic response of shell structures and materials to a pressure pulse. The following subjects are treated: (1) dynamic buckling criterion of shallow shells under uniform impulsive loading, (2) modal analysis of axisymmetric buckling of clamped, shallow, spherical shells, (3) dynamic membrane stresses in a circular elastic shell, (4) dynamic collapse of a rigid-plastic ring under a distributed impulsive load, (5) comparison of rigid-plastic-ring results with experiment, (6) plastic collapse of ring with rigid outer layer, (7) shock wave progagation in solid and compactible media and (8) large elastic deformations of dynamically loaded rings.
