Computer simulation of a boeing 747 passenger jet crashing into a reinforced concrete wall
The purpose of this study is aimed at assessing the capabilities to numerically simulate the dynamic phenomenon of a Boeing 747 jetliner impacting against a reinforced concrete wall. The geometry of the numerical model of the jetliner is adjusted to fit the Boeing data which are available publicly. The thickness of the wall is 3 meters and the impact velocity is 300 km/h. Because of the highly nonlinear characteristics of the phenomenon the strain hardening and the strain rate effects are considered for the constitutive models of the jetliner and the concrete. The simulation shows that the concrete wall exhibits no severe damage by the impact under the conditions assumed in the study.
