Abstract

Abstract

We carried out the analysis of aircraft crashing on the concrete structures through numerical simulation and dynamic analysis using the matured software of ANSYS/LS-DYNA. The analysis uses the same contacting algorithm for four different material models and the results of damage effects are discussed in detail. The numerical simulation results are listed as follows. First, all of four material models can simulate the crashing process of penetration, spallation, and some other local damage effects. Second, if the damage is in front and back side, multiplying with velocity is considered, though the results of MAT072R3 and MAT084 are close to each other. The result of MAT111 is not very close to the previous two models. The model of MAT159 is significantly different from the results of 3 models mentioned above. The results of this research provide some basic parameters for subsequent evaluation of concrete structures resisting under aircraft impact.
