Underwater explosive load calculation and numerical simulation is the key issues of the design of underwater conventional weapons and protection of ships and submarine. Underwater explosion involves strong nonliner problems and multi-material coupling problems. The method of underwater explosion calculation base on the material point method (MPM) is presented. The MPM takes the advantages of the both Euler and Lagrangian methods and overcomes the shortcomings of them. The problems in the underwater explosive simulation such as large deformation, moving material interfaces and deformable boundaries can be solved effectively by the MPM. At last, blast wave produced by TNT exploding under similar infinite water region is computed. The calculated results are in good agreement with the results of empirical formula of Cole and SPH. The simulation results show that the MPM is an effective tool for underwater explosion calculation.
