Structural Response of a Thin Plate due to Underwater Explosion Loading

摘要

To evaluate the reliability of floating structures and submerged structures due to UNDerwater Explosion (UNDEX) loading, it is necessary to estimate the structural response efficiently and exactly. In this study, the basic underwater explosion shock test has performed using the structural model mounting two air backed steel diaphragms and measured the pressure and strain time history data. From a series of tests, the structural response due to bubble pulse is large enough to neglect comparing with that due to the response due to shock wave.
