Underwater explosion is a complex discussion because it has two phase environment including shock waves, bubble effects, cavitation, high strain rate, geometric and material non linearity. Results of underwater explosion tests on the circular steel plates have been discussd. Test results compared with numerical analysis results which it is done by LS-DYNA code. LS-DYNA is the software which is used to analyze large dynamic deflections by use of explicit method. We found that this code has good accuracy to predict the maximum deflections. Strain rate effects included in the program by use of Cowper-Symonds relation.
