Development of Blast Event Simulation

Reaction Engineering International proposes to evaluate the merit and feasibility of developing a suite of next-generation simulations tools to better predict the effects of buried explosive devices on ground vehicles. The blast and soil modeling will be performed using advanced simulation tools developed as part of the DoE ASCI program at the University of Utah (C-SAFE) and the vehicles will be modeled using the DYNA3D FE code and off-the-shelf packages such as LS-DYNA and Hyperworks. The final product will include a hierarchy of blast simulation capabilities, ranging from reduced-order models and decoupled preprocessor-based models, to a comprehensive, tightly coupled simulation tool based on the C-SAFE and DYNA3D codes. The model hierarchy will allow for blast simulations to be performed with varying levels of detail, depending on the required accuracy, ease of use, simulation run time and available computational resources. The final product will have a wide range of applications for both the military and civilian markets.
