On the response of curved laminated panels subjected to transverse impact loads

Using static response characteristics as a tool for understanding impact response\ the in~uence of in!plane and out!of!plane boundary conditions\ the e}ect of curvature\ and the validity of linear and nonlinear plate theory are investigated for the transverse central impact on thin _ber reinforced composite cylindrical panels[ Comparisons between the force!deformation curves of a low velocity impact response and static problem are made[ These curves illustrate the importance of nonlinear e}ects on the large deformation responseincluding the in~uence 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
