Lamb waves propagation for low velocity impact damages analysis in carbon fibers reinforced plates: experimental and numerical experiences

Lamb waves are widely used to detect damage in both metallic and composites structures. This work will present experimental Lamb waves propagation set-up, numerical simulation approach and correlation with experimental results, as well as first analyses oriented to the implementation of a health monitoring system. The technique is applied for the detection and localization of damages induced by “low velocity” impact on carbon fibers reinforced plates (delaminations, matrix or fibers cracking).
