Ultrasonic guided waves in elliptical annular cylinders [PDF]
The Journal of the Acoustical Society of America, 2015 This paper studies the influence of cross-section ovalness or ellipticity on lower order axisymmetric guided wave modes in thin pipes. The second longitudinal mode L(0,2) and the fundamental torsional mode T(0,1) are studied, as these are of interest to current pipe inspection.

Modeling the Effect of Anisotropy in Ultrasonic-Guided Wave Tomography [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022 Most of the existing ultrasonic-guided wave tomography approaches to map structural changes in plate-like waveguides are based on the assumption of an isotropic material model. However, there are many other engineering applications that are made of anisotropic materials and structures.
