Lamb Waves for Detection of Delamination in Composite Plates

Gilad G, Brook A

Research output: Contribution to journalArticlepeer-review


In this paper, a configuration for finding delamination in carbon-based plate like structureis presented and reviewed. Using induced guided Lamb Wave in order to identify damages in a carbon plate by analyzing key distinct features and using support vector machine (SVM) tools to compare data from a delaminated plate and reference training data. This research resets a sensor circle configuration for identifying and scanning delamination in a panel by using the wavelet transform to create a descriptive feature extraction method, then using the known sensor position to create a reliable and robust C-scan.
This method enables both post-production and ongoing monitoring of plate-like carbon-based composite structures. In the form of a low-cost scan option that can detect even sub-surface delamination.
