Tag: Guided waves
There are a number of methods of simulating ultrasonic guided wave propagation in COMSOL (v6.1) which I will discuss in
2D-FFT can be a really powerful tool in identifying the propagation of different Lamb wave modes in a signal. The process was pioneered by Alleyne and Cawley (1990), and has since been used for a wide range of applications. In this post I will explain how 2D-FFT can be implemented in MATLAB, and how the results can be compared against dispersion curves.
