Computational modelling of bird strike impact on an aluminium alloy plate via coupling of FE-SPH

This paper proposes a parametric mechanics study in determining the relationship between the parameters of the aerospace structure during a bird strike impact. A commercial software of LS-Dyna is used to compute the numerical modelling demonstrated in this research. Technically, an idealised bird is modelled as a cylindrical shape with hemispherical ends to maintain the homogeneity and symmetry using Smoothed Particle Hydrodynamics (SPH) approach. At the same time, an aluminium alloy plate is developed as a shell element plate in the finite element model. Such conditions are considered in this research from the view of bird strike impact under various conditions (structural thickness) and constraints (bird size). The obtained computational results are in close agreement with the experimental results published in another literature
