Abstract
This paper presents a theoretical model for anisotropic wave attenuation in composites. The model has been implemented in a software called FIBREWAVE in order to predict dispersion and attenuation of S0, A0 and SH0 Lamb wave modes. The required input data are the complex stiffness matrix coefficients of the unidirectional plies of the laminate, which have been measured by a laser interferometry method. Complex stiffness data for an unidirectional CFRP laminates are moreover presented. Satisfactory agreement has been observed between predicted and experimental group velocities and wave attenuations.
