Abstract:
The document details a computer simulation of an F-4 Phantom aircraft impacting a reinforced concrete wall. This type of simulation is crucial for assessing the integrity of structures like nuclear power plant containment buildings under extreme loading conditions. The simulation was performed using a high-resolution finite element model that represents both the aircraft and the wall. The aircraft model includes detailed geometry and material properties to accurately capture its deformation and fragmentation upon impact. The concrete wall model, developed using a specialized constitutive model, accounts for nonlinear behavior such as cracking and crushing. The simulation employs an explicit finite element program, such as DYNA3D, to handle the high-speed dynamic interaction and large-scale deformation involved in the crash event. The analysis of the simulation results provides detailed insights into the forces exerted on the wall, the energy absorption mechanisms of the aircraft, and the overall structural response of the concrete barrier. This work demonstrates the capability of advanced finite element analysis to model complex, catastrophic events, thereby contributing to the safety and design validation of critical infrastructure.
