On the response of curved laminated panels subjected to transverse impact loads. (English) Zbl 0951.74043

Summary: Using static response characteristics as a tool for understanding impact response, the influence of in-plane and out-of-plane boundary conditions, the effect of curvature, and the validity of linear and nonlinear plate theory are investigated for the transverse central impact on thin fiber reinforced composite cylindrical panels. We make comparisons between force-deformation curves of a low velocity impact response and static problem. These curves illustrate the importance of nonlinear effects on the large deformation response, including the influence of curvature. The static response is a lower limit to the impact response and, for the present circumstances, can give insight into low velocity impact response behavior.
