Abstract: A bird model which is used in bird-windshield strike analysis is established in comparison with to the standard solutions, and the failure criterion of windshield suggested is that the strain produced is greater than the critical strain of the windshield material. Then LS-DYNA is employed to analysis the bird-windshield impact response. The dynamic stress, strain and displacement of the windshield are obtained, and the critical velocity when the windshield failure is also gotten on the FE analysis. The analytical results are compared to those of the experiment and both are consistent fairly well.

Key words: windshield, bird impact, coupled solution, decoupled solution, critical velocity
