Development of a Strategy for Simulating Blast-Vehicle Interactions
Abstract
This report describes research and development activities supported by contract W56HZV-08-C-0126, which was funded under the SimBRS program, to develop a strategy to perform high-fidelity simulations of blast-vehicle interactions including complex phenomena such as detonation, coupled fluid-structure interactions, and non-linear structural response to severe, time-dependent pressure loads and debris impact. The contract leveraged ongoing development efforts for the high-fidelity flow solver Loci/CHEM to produce a fully Eulerian numerical capability to simulate blast phenomena in fluids and solids. The resulting code was christened Loci/BLAST. Included in this report are: an assessment of existing technology; a discussion of the implementation of the Jones-Wilkins-Lee equation of state and a prescribed burn function within Loci/BLAST; results from simulations of blast interactions with realistic rigid geometries; a discussion of the implementation of the models needed to simulate blast-soil interactions within Loci/BLAST and the associated validation activities; results from simulations of blast interactions with debris; and preliminary results from coupled fluid-structure interaction simulations using Loci/BLAST and LS-DYNA. The results reported here demonstrate that it is possible to perform blast simulations, including both fluids and solids, within a unified Eulerian framework. These results lay the groundwork for the new strategy that is described in the report.
