A Comparative Study on the Impact Behaviour of the Coated Glass Plates by FSDT and HSDT

Whitney and Pagano's First-order Shear Deformation Theory (FSDT) and a refined Reddy's Higher-order Shear Deformation Theory (HSDT) are used to interpret the impact behaviour of coated glass plates when they are impacted by an foreign object, The results are to be reviewed in a comparative manner to study the theory and impact behaviour appropriate for future qualitative and quantitative predictions. Consequently, in the macroscopic behaviour aspects (contact force, deflection, kinetic energy), the results of the analysis of FSDT and HSDT for coated glass plates do not differ much. However, there are limits in the microscopic behaviour aspects. That is, both simple FSDT and refined HSDT can be permitted for the macroscopic predictions, but uses of FSDT are limits for microscopic behaviour predictions.
