Impact Response of the Film Mechanical Properties of the Coated Glass Plate

The influence of film property on dynamic behavior of the coated glass plate under foreign object impact is studied by the developed numerical simulation program. To analysis the impact responses, a powerful numerical simulation in conjunction with the Reddy's theory and a generalized power method is suggested. The properties of films of coated glass, i. e. the elastic modulus, change, but not the properties of glass. Four typical film and glass combinations, namely, α=1, 2, 5, and 10are assumed. We can see that as α increases, the contact force becomes smaller and plate deflection increases. That is to say, the impact response in α=1 is much faster than that α=10. And also, we can observe that as the ratio α increases from the results of the stress analysis through the thickness, the risk of failure of the film and the glass interface is less.
