Using passive and active acoustic methods for impact damage assessment of composite structures

This study aims to use the passive and active acoustic-based health monitoring methods for impact damage assessment of composite structures. To this aim, a Carbon Fiber Reinforced Polymer (CFRP) composite plate was fabricated and subjected to a simulated low-velocity impact by performing repeated quasi-static indentation tests where a loading...

Temperature effects on an Acoustic Emission based Structural Health Monitoring System: Applied to Composite Materials

Acoustic Emission (AE) based structural health monitoring systems have the potential to assess the state of metallic / composite structures and detect damage in real time as it grows. This is done by monitoring the Lamb waves that occur due to the release of energy and the specific boundary conditions. Environmental and Operational Conditions ...
