Simulation of local damage to reinforced concrete structures caused by impact of aircraft engine missiles

Aircrafts crashing into reinforced concrete structures can produce structural damage including local damage caused by the deformable engines and global damage caused by the entire aircraft. Studies of local damage from aircraft engine impacts are most-often military-centered. Many formulas have been proposed to evaluate this type of damage. A test program has been performed in the USA and Japan to select suitable empirical formulas for predicting the local damage caused by the rigid missile. These studies attempted to account for engine deformation though reduction factors. This paper focuses on numerical simulation to study the local loading effects of aircraft engine impacts on concrete structures. We compare our results with those from the test programs performed in the USA and Japan
