Functionally graded shells subjected to underwater shock [PDF]
AIP Conference Proceedings, 2012 This paper deals with the problem of functionally graded (FG) cylindrical shells subjected to underwater shock. A computational approach to predict the dynamic response of the FG cylindrical shells to underwater shock is presented. The effective material properties of functionally graded materials (FGMs) for the cylindrical shells are assumed to vary ...

Treatment of marine microorganisms using underwater shock waves driven by imploding detonation
Nihon Kikai Gakkai ronbunshu, 2018 Effects of underwater shock waves driven by imploding detonation on marine microorganisms have been experimentally studied. The detonation tube was initially charged with a stoichiometric C3H8-O2 mixture, while a test section was filled with water ...
