Evolution of Occupant Survivability Simulation Framework Using FEM-SPH Coupling

摘要

To reduce the hazard for service personnel involved in current field operations, it is necessary to improve the safety and structural integrity of transport vehicles subjected to buried explosive material. Numerical simulation of the detonation effects of an Improvised Explosive Device (IED) on a vehicle and its occupants can provide tremendous value in this effort. Such events involve a range of complex phenomena at various dimensional and temporal scales, and it is not practical to capture all physical phenomena with just one single numerical method. A practical solution to this problem is proposed using a combination of Smoothed Particle Hydrodynamics (SPH) and Finite Elements.
