Abstract

Abstract

The simulation analysis of the impact test of 1/7.5 scaled aircraft model impacting the steel plated concrete walls is carried out by using finite element code of ANSYS/LSDYNA. Two models of different material (i.e. Winfrith model and CSCM model) are used to simulate the concrete. The comparison analysis of damage profile of walls and residual velocity of aircraft engine between the simulation results and test results is presented. The results indicate that the damage modes of the impact simulations are in agreement with that of the experiment. Furthermore, Winfrith concrete model is better for simulating the nonlinear performance of concrete with big strain and high strain rate than CSCM concrete model. It is verified that not only the selection of the material constitutive models for the steel plated concrete wall and aircraft model but also the entire analysis process is appropriate and effective.
