This paper takes the reaction of the GRP monocoque (frameless) construction ship under the underwater explosion as the research object. First using MSC.Dytran to establish a simulation model of TNT in underwater explosions, verify the relevant parameters settings; then establish ship model, analyze its response of various parts under underwater explosion, and use Tsai-Wu damage criterion to check material’s failure. The result of the underwater explosion simulation are mainly divided into un-destruction(should be), destruction and un-destruction(improved). It is hoped that the result of this paper can be used as a reference to help ship designer or relative researcher shorten the exploration time in simulation of the response of GRP ship subjected to underwater explosions.
