Description	The impact response and the impact-induced damage in laminated composite cylindrically curved panels subjected to a transverse impact by a metallic impactor are studied using a threedimensional non-linear finite element formulation. A layered version of a 20 noded hexahedral element incorporating geometrical non-linearity is developed based on the total Langragian approach. The nonlinearity of both strain displacement relation and contact loading are simultaneously solved iteratively using the Newton-Raphson method. Impact-induced damages (matrix cracking and delamination) are predicted using appropriate three-dimensional stress-based failure criteria. Example problems of graphite/epoxy cylindrical shell panels are considered and the influence of a geometrical non-linear effect on the impact response and impact-induced damage is demonstrated. Effects of different parameters such as impactor velocity, shell curvature, laminate dimension and fibre orientation of plies are also investigated.
