Underwater explosion shock response analysis of a MIL-S-901D Standard Floating Shock Platform(SFSP) was performed using LS-DYNA/USA, and the accuracy of analysis results was examined through the comparison of them with the existing test results. Surrounding fluid as well as the SFSP was included In a three dimensional finite element model for the consideration of the cavitation effects of UNOEX shock wave. It was confirmed that the analysis results could predict accurately the shock behaviors of the SFSP, and the response characteristics according to heavy weight shock tests could be figured out well.

Shock responses of the MIL-S-901D standard floating shock platform("SFSP") subject to underwater explosions(UNDEX) are analyzed by using the LS-DYNA/USA. For the analysis, surrounding fluids as well as the SFSP are included in a 3D FE model to consider the cavitation effects of the UNDEX shock wave. The calculated results are compared with the existing test results and it is confirmed that the analysis results predict accurately the shock behaviors of the SFSP.
