The paper deals with the problem of Lamb waves dispersion curves sensitivity to the change of elastic constants in composite materials. The framework of the present work is a more general problem of material constants identification in thin plates made of composite materials. The approach is based on the analysis of guided waves propagation and the related dispersion curves to find the underlying material elastic constants. In present work a numerical study is performed to identify measurement directions and wave propagation modes that are most sensitive to the change of the particular elastic constants. This approach will allow to optimize the material constants identification procedure and experimental setup by specifying the preferred measurement directions and wave propagation modes. The approach can be used within the Structural Health Monitoring framework to monitor material degradation of plate-like structures made of composite materials.
