Effect of transverse cracks on lamb wave velocity in CFRP cross-ply laminates

The stiffness and velocity of lowest order symmetric (S sub(0)) mode for CFRP cross-ply laminates with various transverse crack densities were measured. Linear AE source locations were conducted on the damaged specimen and the effect of reduction of S sub(0) mode velocity on the accuracy of source l...

Summary:The stiffness and velocity of lowest order symmetric (S sub(0)) mode for CFRP cross-ply laminates with various transverse crack densities were measured. Linear AE source locations were conducted on the damaged specimen and the effect of reduction of S sub(0) mode velocity on the accuracy of source location was investigated. Results indicated that a combination of active and passive sensing was found to be effective in precise evaluation of transverse cracks.
