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.
