- Abstract
Numerical simulations of bird-striking composite plates were conducted by using smoothed particle hydrodynamics and finite element method to evaluate the failure criteria. The damage prediction capability of four composite failure models (MAT22, MAT54, MAT55, and MAT58) with Shell and TShell element formulations was evaluated by using the finite element software LS-DYNA, and the numerical results were compared with the experimental results. Results show that the damage distributions of different composite material models differ significantly under high-velocity impact conditions. The time histories of the impact force and the kinetic energy of bird are similar for the four models. This condition can be attributed to the fact that the materials' strength and elastic parameters are the same between the different models. The damage characteristics of MAT55 and MAT22 with TShell elements are poorly related to the experimental results. MAT58 with Shell and TShell element formulations shows good agreement with the experiments, and the TShell element can better avoid the boundary effect during the impact process.
