Effects of Cavitation on Underwater Shock Loading - Plane Problem

摘要

Final results of an investigation of the effects of response-induced cavitation on underwater shock loading are reported. Data were obtained by finite element modeling of a submerged sandwich shell and a surrounding plane fluid region. Representative curves are presented showing shell bending stress, hoop compressive stress and contents acceleration as functions of time. It is concluded that, for the range of parameters considered, cavitation does not increase the severity of loading on structure or equipment. Application of the finite element modeling technique is recommended for investigation of bulk cavitation and its effects on structural loading. (Author)
