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
