Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Surface-bonded single-mode optical fibre sensors have been used to monitor the interaction of ultrasonic S-0 lamb waves with defects in carbon iibre composite plates. Lamb waves were initiated using Perspex-coupled piezoelectric transducers. The defects investigated comprised holes, regions of impact damage and delaminations. Holes could be identified by analysing direct S-0 reflections and impact damage by S-0 back-waif echo amplitude. Large delaminations gave a poor direct S-0 reflection. Evidence was found for mode conversion at centre plane delaminations.
