Composites generally are not damage-tolerant, and impact damage can significantly degrade the compressive strength of a composite laminate. Even when no visible impact damage is observed at the surface (energies below barely visible impact damage (BVID)), matrix cracking and interlaminar failure can occur and the carrying load of the composite laminates might be considerably reduced (de Freitas et al in Compos Struct 42(4):365–373, 1998). The aim of the multisite damage assessment tool is to give quick answers with regard to remaining airworthiness and further investigations after hail strikes and reducing aircraft on ground time. To clarify the remaining airworthiness of an aircraft after multisite damage (MSD), mainly caused by hail strikes, an assessment tool is developed based on physical and virtual testing as well as accuracy factors of structural health monitoring (SHM) information.
