Simulation of Concurrent Detonation of Multiple High Explosive Charges
A 1D spherical LS-DYNA Multi-Material Arbitrary Lagrange Eulerian (MM-ALE) model was constructed to simulate the three single charge events reported in MABS 25 manuscript P-029 Stojko, et al. (2018). These three simulations were repeated using 2D axisymmetric meshes. Multiple charge simulations were made using 2D axisymmetric and 3D models of the double and triple charge experiments. As stated by Stojko et al. “The primary purpose of the experiments was to provide a database of results for the validation of numerical modeling of the effects from multiple high explosive charges.” The model results presented in this manuscript support this statement of the data representing a valuable validation database for both single and multiple charge explosions.
