PREDICTION OF IMPACT RESPONSE OF REINFORCED CONCRETE SLABS SUBJECTED TO IMPACT OF AIRCRAFT ENGINE MISSILE : Verification by the Results of Full-scale Impact Tests using Real Jet Engine

Abstract

It is of importance to investigate and predict the response of reinforced concrete structures to impact loading from the view point of disaster prevention at nuclear power plant facilities, and there is an urgent requirement for establishment of design methods against the impact of aircraft and/or its engine. The authors proposed a numerical approach for assessing local response characteristics by the high-velocity impact of deformable missiles, and the results of numerical analyses were verified by that of full-scale impact tests using real engine body (GE-J79) reported by Muto et.al. The relation between the crash strength of engine body and the limit thickness of perforation was calculated and illustrated in this paper.
