Description
Summary:This paper presents an experimental and numerical study of the bird strike on a 2024-T3 aluminum double plate. The experiments are carried out at a desired impact velocity of 150 m/s. The explicit finite element software PAM-CRASH is used to simulate the bird-strike experiments, and a coupled SPH-FE method is adopted, where the bird is modeled using the SPH method with the Murnaghan EOS and the structure is meshed with finite elements. The material parameters are identified by an optimization process, and the simulated dynamic responses of bird strike are compared with experimental measurements to verify the numerical model. The displacement and strain of the plate as well as the final deformation and damage show good agreement between the simulation and the experimental results. It suggests that the coupled SPH-FE method can provide an effective tool in designing bird-strike-resistant aircraft component.
