The development of analytical tools for predicting the high-energy impact resistance of lightweight composite aircraft structures would improve component maintainability and potentially flight safety. The tool should predict the amount of absorbed energy and the degree of component damage. The task is quite difficult due to the nature of the composite materials and the non-linear failure of the structure and impacting object. The structure analyzed in this study is a transport category aircraft nose radome impacting a 4 lbs. 'bird' at 300 knots. There are disparities between analyzed and actual impacts due to the analysis codes inability to model certain composite failure modes (delamination & sandwich peel).
