“…Among these methods, SPH can better describe bird fragmentation into discrete particles with high efficiency. Therefore, SPH has recently experienced high popularity [2,5,10,15,16,32,33,40,41] in bird strike, high-velocity impact, and other large deformation studies. In the present study, a SPH method was employed, represented by a set of discrete but interacting particles, which belong to a meshless particle-based method.…”

“…For these applications, composite laminates undergo complex internal damage when they are subjected to foreign object damage (FOD) via impacts. In terms of composite materials under impact loadings, the laminated layup will be critically vital [16][17][18]. With much more complexity compared to metal materials, several failure modes in composite materials can be caused by impact loading, such as fiber fracture, matrix cracking, delamination, etc.…”

“…Hedayati et al [17,31] conducted a bird strike analysis with different layup materials and different positions of the reinforced ply. Recently, Mohagheghian et al [16] found that the polymer interlayer type had the most significant effect on both deformations and failure modes of the laminated glass windows at room temperature. Riccio et al [32] analysed the state-of-the-art formulations for the bird and composite wing modelling in detail, providing discussion on the added value and the weak points.…”

Composite laminates can potentially reduce the weight of aircrafts; however, they are subjected to bird strike hazards in civil aviation. To handle their nonlinear dynamic behaviour, in this study, the impact damage of composite laminates were numerically evaluated and designed by means of smoothed particle hydrodynamics (SPH) and the finite element method (FEM) to simulate the interaction between bird projectiles and the laminates. Attention was mainly focused on the different damage modes in various laminates’ plies induced by bird impact on a square laminated plate. A continuum damage mechanics approach was exploited to simulate damage initiation and evolution in composite laminates. Damage maps were computed with respect to different ply angles, i.e., 0°, 45° and −45°. The damage distributions were comparatively investigated, and then the ply design was considered for crashworthiness improvement. The results aim to serve as a design guideline for future prototype-scale bird strike studies of complex laminated structures.

“…Regarding bird strike studies on aircraft windshield targets, most investigations have focused on numerical simulations, with only a limited number of reported experimental studies (Doubrava and Strnad 2010;Doubrava 2011, Kangas and Plgman 1950and Mohagheghian et al 2018. Doubrava et al (Doubrava and Strnad 2010;Doubrava 2011) studied the performance of laminated windows with overall thicknesses of 14, 18 and 20 mm against impact by a 1.81 kg bird at a velocity range of 83-125 ms -1 .…”

Bird strike on aircraft remains a serious threat to flight safety. Experimental investigations employing real birds are associated with high cost and low reproducibility. Therefore, physical substitute materials are often used instead of real birds. This study investigates the soft impact loading on aluminium and laminated glass targets from ballistic gelatine and rubber projectiles. The two targets simulate strike on the aircrafts' fuselage and windshield respectively. The full field out of plane displacements of the targets were recorded for velocities 110 to 170 m s-1 using digital image correlation during gas gun experiments. A simulation model based on Smoothed Particle Hydrodynamics was developed and validated against the experimental data from all four projectile-target material combinations. It was shown that for the same momentum, a rubber projectile exerts a higher pressure on a target as compared to gelatine, even though the out of plane displacements and in-plane strains are similar. This led to fractures in the impacted laminated glass when rubber was used. The study offers new experimental data as well as efficient design modelling tools to mitigate damage imposed during bird strike. The models provide a way towards enabling the optimisation of real, large scale aircraft structures and components.
