Abstract:
This report investigates the structural response of reinforced concrete facilities to high-speed aircraft impact, with a specific focus on fluid-like deformation modeling and hydrodynamic particle methods. Utilizing the LS-DYNA simulation suite, the study models aircraft using Smoothed Particle Hydrodynamics (SPH), enabling detailed representation of mass/momentum transfer and hydrodynamic interactions during crash scenarios. Key findings demonstrate the effectiveness of SPH in capturing high-deformation behavior and energy transfer mechanisms, particularly in modeling fuselage crushing and fuel mass distribution, which are critical in evaluating structural resilience under regulatory standards. The simulations inform best practices for modeling reinforced concrete structures against extreme hydrodynamic loading conditions.
