Numerical analysis of bird impacting composite laminates and the influencing factors on absorbing energy

摘要

The numerical analysis is a very important work in the process of doing research on damage design of composite laminates resisting bird impact. The numerical analysis about bird impact on the laminates in the paper used the transient nonlinear finite element method combining the experiment of reference. The paper analyzed the initialdamage of laminates, the stress, and strain of each layers at a certain moment. It also analyzed the influence of ply stacking sequence, parameter of laminates and the shape of the bird on the energy absorbed by laminates. The results of this paper are of referenced value to the research on composites structures resisting bird impact.
