Damage characterization of laminated composites using acoustic emission: A review (2020, neutral): “Gutkin et al. [75] conducted five different types of test, including The second level of damage assessment of a composite structure is partitioning the AE signals of different damage mechanisms.”
Feasibility and limitations of damage identification in composite materials using acoustic emission (2015, background): “A widely-used approach for polymer matrix composites considers the peak frequency of AE signals (frequency of highest magnitude) and defines a specific range of values for each damage mode [7–10].”
Damage classification in carbon fibre composites using acoustic emission: A comparison of three techniques (2015, background): “Summarised by Gutkin [10], early approaches looked simply to classify damage based on a single AE parameter, such as the study by Valentin et al. [11] which used the peak amplitude of the waveforms to distinguish between matrix cracking and fibre break signals.”
Clustering of interlaminar and intralaminar damages in laminated composites under indentation loading using Acoustic Emission (2018, neutral): “13), however, most of the researchers reported that matrix cracking has the lowest frequency content, ﬁ ber failure has the highest frequency, and the frequency of delamination signals is located between these two damages [31,50,53].”
