Coupled Euler-Lagrange Simulation of the Jolt HE Event and Relevance to the Shock Physics Experiments
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
The goal of the Shock Physics Experiments is to increase our understanding of the shock phenomenology from an explosive event to aid in modeling these events. A more accurate understanding of the effects of near source geology on that phenomenology is critical. We demonstrated the use of the multi physics Abaqus® fully coupled Euler-Lagrange code to model the DTRA JOLT experiment. Abaqus/CEL was able to compute the high-deformation explosive loading, the complex rock response with damage, and the large general contact domain. Comparison of results to test data reveals that the simulation performed credibly. These results provide insight into propagati0n of explosive-caused shock in jointed media. This exercise provides evidence that the shock front is not perturbed by the joints. While it is possible that later time, lower amplitude portions of the waveform can exhibit behavior caused by joints, we conclude that the main shock events from the SPE events is not effected by the local jointing.
