Investigating Effect on Contact Stiffness on the Low Velocity Impact Response of Curved Composite Plate
Authors: Buddhi Arahchige, Hessam Ghasemnejad, Andre Agousti
Abstract: The low velocity impact response of a curved stiffness composite panel is studied. A two degree of freedom spring-mass model is used to evaluate the contact force between the composite panel and the impactor. This work uses the Hertzian contact model which is linearized for the impact analysis of the curved composite panel. First order shear deformation theory coupled with Fourier series is used to derive the governing equations of the curved composite panel. In this paper, the effect of contact stiffness on the impact force is studied analytically. The results showed that the impact force increased with increase of contact stiffness.
