Abstract

In this study, acoustic emission was evaluated as a supplementary nondestructive testing method for detecting damage initiation and progression, identifying the site of damage, and anticipating ultimate fracture in notched full-scale honeycomb sandwich composite fuselage panels using redundant arrays of different acoustic emission sensor models. Each panel contained different damage scenarios and was subjected to combinations of quasi-static hoop and longitudinal loads. Damage progression and location were characterized with various inspection techniques, and the acoustic emission results were correlated with photogrammetric strain fields. Applying post-test signal processing, acoustic emission accurately detected notch tip damage initiation and tracked its progression to ultimate failure.
