This paper focuses on the comparison between underwater explosion (UNDEX) shock
loading empirical formulations. First, the numerical simulations for a cylindrical pressure hull
subjected to UNDEX loading were conducted and the results are close to the failure modes shown in
experiments of Kwon (1993). Second, the empirical UNDEX loading formula of Cole (1948), Keil
(1961) and Shin (1994) used in cylinder subjected to underwater shock loading were compared. The
simulation results by using three empirical formulas were compared and Shin’s (or Cole’s) empirical
formula was shown to be better than the other empirical formulations when subjected to an UNDEX
under the same conditions. The analytical results offer a valuable reference to the research of
underwater explosion.
