Abstract

Acoustic source localization techniques for composite laminates are challenging for anisotropic materials. In this paper, an improved signal energy-based acoustic source localization technique without a priori knowledge of the principal axes orientations is proposed. The proposed technique has the advantages of no need to measure arrival time and does not need complex signal processing techniques. It can also be applied in the case of low signal-to-noise ratio. Finite element models of carbon fiber laminate with different stacking sequences are created to verify the proposed technique. The results of the numerical simulation demonstrate the feasibility of the proposed technique.
