Nondestructive Evaluation of Composite Laminates by Leaky Lamb Waves Using a Bubbler Device
The application of Leaky Lamb waves (LLW) to nondestructive testing in field conditions was studied using a bubbler device. To reduce the sensitivity of LLW modes to surface curvature, the dispersion curve of LLW in graphite/epoxy laminates was used in the design of the bubbler. The results are described and discussed.
