Advanced aircraft analysis of an F-4 Phantom on a reinforced concrete building

• Aircraft impact analyses are performed using the missile-target interaction method.
• Three types of FE models of a F4-Phantom aircraft considering the fuel mass effect are considered with erosion effect.
• The aircraft impact models are verified through the comparative studies with experimental data.
• The parametric studies on the fictitious nuclear concrete containment wall are investigated.
• The SPH or Hybrid models show severe damage to the deformable constrained concrete wall than does Lagrangian based model.

The nonlinear dynamic fracture and collapse characteristics of an F-4 Phantom aircraft under an extreme load caused by the impact of an F-4 Phantom are investigated. Three types of FE models considering the fuel mass effect are developed to investigate the superiority of the developed model. A rigid wall impact test is conducted to determine the material properties and the eroding failure criteria. The impact forces exerted by the aircraft against mounted thick concrete walls are then verified by comparing the results here with earlier experimental data obtained from an actual-scale F-4 Phantom aircraft impact test conducted by Sandia National Laboratory. Validation of the methodology is further investigated by extending the comparative studies to a constrained thin concrete wall similar to the type used in nuclear power plant containment buildings. The experimental and simulation results are also analyzed and discussed.
