Research Objective• Develop an efficient and accurate methodology–
using high-fidelity multi-physics software–to estimate vehicle and occupant vulnerability to buried blast threats.
Challenges• Complexity of numerical models required to
accurately simulate physical behavior• Stability of numerical algorithms • Quantification of uncertainty and stochastic
modeling approaches
Future Applications
ARL Facilities and Capabilities Available to Support Collaborative Research
Complementary Expertise / Facilities / Capabilities Sought in Collaboration• Development of reduced-order meta models from
complex computational physics models• Innovative methods for modeling soil and
explosive interactions with vehicle structures• Novel finite element formulations and contact
algorithms• Automated techniques to develop intricate
structural meshes
