Abstract
The results of an analytical and experimental study of the effect of impactor mass and plate radius of curvature on the low-speed impact response of laminated composite plates is presented. Dropped-weight and airgun impact responses, damage characteristics, and residual strengths of quasi-isotropic and orthotropic plates are presented for a range of impact energy levels determined by systematically varying the mass of the impactor. The flat plate responses are compared with the responses of curved plates with three different radii of curvature. Measured contact forces and damage areas are also presented. The results indicate that contact force and damage area are nonlinear functions of the impactor mass and vary considerably over the entire range of impact energy levels considered. The different damage levels caused by impactors with a given impact-energy level and with different masses significantly influence the compressive residual strength of impact damaged plates. The trends in the results for contact force, damage area, and compression-after-impact strength are clear and consistent when the data are expressed as a function of the impactor momentum. The contact force, damage initiation, and residual strength results for curved plates suggest that the low-speed impact response of plates is also a function of the radius of curvature.
