The effects of film properties on impact response of the coated glass plate under foreign object impact are studied by the developed finite element simulation. To analysis the impact responses, a powerful finite element approach in conjunction with the Reddy's higher-order shear deformation theory and a generalized power law is suggested. The mechanical properties of the coated films are changed with elastic modulus but those of glass plates are fixed. Four typical film and glass combinations, namely, the ratio of the elastic modulus of glass to that of film α(=Eg/Ef)=1, 2, 5 and 10 are considered. It can be seen that as the ratio α increases, the contact force becomes smaller and the plate deflection increases. That is, impact responses in hard film-hard glass plate systems (α=1) are more sensitive than those of soft film-hard glass plate systems (α=10) in the same film/glass thickness. 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.
