We build this car accident model with bird's hitting, in order to simulate and analyze car windscreen accidents with high vehicle speed. In this model, you can predict and simulate windscreen's deformation based on different conditions such as vehicle speeds, bird hitting angles, thickness of glass, and glass materials. The impact force, stress distribution, strain and deformation of windscreen can be simulated and analyzed based on this model too. 
We may help you do more failure analysis based on your requests. Order this one or send us a quote! Thank you!
