Cavitation Effects on a Ship-Like Box Structure Subjected to an Underwater Explosion

This thesis investigates the characteristics of cavitation and its effect on a ship-like box structure subjected to an underwater explosion using the finite element method. It explores how cavitation, caused by tensile fluid pressure, influences the dynamic response of the structure under varying standoff distances and depths from the free surface.

Ship Shock Trial Simulation of USS Winston S. Churchill (DDG 81)

Young S. Shin and Nathan A. Schneider

This paper investigates the accuracy of ship shock simulations, presenting a valuable alternative to costly and dangerous physical shock trial tests. It specifically focuses on modeling the USS WINSTON S. CHURCHILL (DDG 81) and comparing simulation predictions with actual shock trial data from three underwater explosions.

Prediction of Surface Ship Response to Severe Underwater Explosion

Nathan A. Schneider

This thesis proposes and demonstrates a virtual underwater shock environment approach to predict the response of surface combatant ships to severe underwater explosions using non-linear finite element simulations. It analyzes both hull girder and local structural responses to dynamic loads, confirming the viability of this simulation method for ship shock prediction, though further work on damage and global collapse is needed.
