Shock wave loading of reverse detonation model

To achieve the dynamic loadings on the large -sized specimens by the explosive shock waves equivalent to the stress wave obtained by a light -gas gun, based on the principle of superposition, the reverse detonation model was introduced to accomplish the shock wave loading on the compressible solid materials.The interferences were comprehensively considered for each free edge of the explosives and the material specimens by the rarefaction waves.By integrating the velocity-pressure curves of the explosion products and the compressible fluids, the calculation methods were theoretically proposed for the shock pressure and the shock wave loading platform width, respectively.And the theoretical analysis results were verified by combining the numerical simulation.They are consistent with each other.
