Abstract:
Due to the lack of longitudinal stiffening along submarine hulls, they are inherently vulnerable to underwater explosions directly off the bow or stern. Accordion-like deformations of the hull are set into motion which could cause dynamic amplification in the transient response of attached substructures. In underwater shock acceptance tests of internal equipment, this interaction is created by exploding a charge in a fore and aft configuration with the submerged shock test vehicle SSTV. With the increasing availability of large computers and the rapid development of numerical methods, several computer codes have been written to predict equipment response to underwater shocks. Using the ELSHOK ELASTIC SHOCK code, this thesis investigates the effect of hullsubstructure interaction on stiffened shell response at resonance following an end-on load. The transient response of the coupled shellsubstructure system from tapered and conventional charges of equivalent impulse is examined in this study. Keywords End-on shock loads.
