Abstract

This research investigates two co-cured joint configurations, the conventional single lap joint, and the modified single nested overlap joint, which is obtained by a minor alteration of the former configuration. A systematic comparison of damage initiation, damage progression mechanisms, and failure modes of co-cured joint specimens under quasi-static tensile loading is carried out. Several investigation methods are used including acoustic emission, visual observation, optical microscopy, and X-ray radiography.
