Open Guided Waves: online platform for ultrasonic guided wave measurements [PDF]

open access: yesStructural Health Monitoring, 2018
Ultrasonic guided waves have been used successfully in structural health monitoring systems to detect damage in isotropic and composite materials with simple and complex geometry. A limitation of current research is given by a lack of freely available benchmark measurements to comparatively evaluate existing methods.
