| Abstract: | A numerical analysis model for bird striking multilayer windshield structure has been established with the non-linear,explicit dynamics finite element program LS-DYNA.The bird was represented by an idealized geometry and the material model was defined by a kinematical hardening model with strain rate dependency.An ALE element formulation was used to represent the motion of the bird,whereas the multilayer windshield was described by a Lagrangian reference configuration.The windshield material was defined by ... |
