“…Low energy impact damage in composite structures has been the subject of numerous studies, e.g., [3][4][5][6][7][8][9][10][11]. However, few studies have been reported on modeling the progressive failure in thin shell composites.…”

“…For tool drop, typical failure mechanisms are a combination of delamination, matrix failure, or back-face tension failure, with back-face fibre damage being the external visible damage [10]. Kim et al [11] stated that there was no correlation between dent depth, peak force of impact, and development of significant internal damage for thin composite plate and shell structures.…”

“…A critical safety issue for the design of primary aircraft structures is vulnerability and damage tolerance due to mechanical loading such as foreign object impacts from bird strike, hail, tire rubber and metal fragments [5,6]. New composite aircraft structures are vulnerable to impact damage, due to the relatively thin composite skins and the generally brittle behavior of carbon fiber reinforced epoxy resins.…”

This paper discusses the topic of how the integrity of safety-critical structural composites can be enhanced by the use of structural health monitoring (SHM) techniques. The paper starts with a presentation of how the certification of flight-critical composite structures can be achieved within the framework of civil aviation safety authority requirements. Typical composites damage mechanisms, which make this process substantially different from that for metallic materials are discussed. The opportunities presented by the use of SHM techniques in future civil aircraft developments are explained. The paper then focuses on active SHM with piezoelectric wafer active sensors (PWAS). After reviewing the PWAS-based SHM options, the paper follows with a discussion of the specifics of guided wave propagation in composites and PWAS-tuning effects. The paper presents a number of experimental results for damage detection in simple flat unidirectional and quasi-isotropic composite specimens. Calibrated through holes of increasing diameter and impact damage of various energies and velocities are considered. The paper ends with conclusions and suggestions for further work.
