Abstract

Composite materials exhibit complex phenomena associated with damage onset, and are characterized by significant uncertainties in their material properties. The development of damage resistance design methodology, especially for damage induced by low velocity impacts in aircraft structures, have allowed a more efficient management of the damage in composites. In this paper a probabilistic approach has been adopted in order to evaluate the impact of the material properties scattering on the damage resistance of a composite panel. Furthermore two different composite panels have been investigated and compared in order to detect, based on a probabilistic approach, the one exhibiting the best performances in terms of damage resistance.
