Abstract

Guided waves have been widely used in different fields of engineering, such as non-destructive evaluation, seismology and oil & gas. Successful applications of guided waves are dependent upon thorough understanding of their modal properties. However, the prediction of the behavior of guided waves could be challenging for complicated waveguides, for example embedded/immersed waveguides with significant energy leakage, anisotropy waveguides with mode coupling effect and prestressed waveguide with acoustoelastic behavior. In this paper, we develop a generalized tool to study the modal properties of complex waveguides using semi-analytical finite element (SAFE) method. It is based on acoustoelastic equations with an option to add perfectly matched layers for open waveguides. The model is implemented into a commercial software package, providing easy access for a wide range of researchers. The model is first validated by well-established solutions in the literature, and then applied to a few practical cases in different fields, demonstrating its great potential in guided wave applications.
