Skin-stringer interface failure investigation of stringer-stiffened curved composite panels under hail ice impact

Large scale aircraft composite panels can be damaged by hail ice in high speed ductile impacts (without penetration by sharp shape) and predicting the damage modes and failure mechanisms under these complex boundaries and loading conditions poses a unique challenge. Thus, the dynamic behavior and failure of stringer-stiffened curved carbon/epoxy composite panels impacted by hail ice at two classic locations (mid-bay of impact type I and...
