125) Here, atmospheric Lamb wave propagates non-dispersively in the horizontal direction with a sound velocity of about 310 [ms.
Damage detection in composite materials using Lamb wave methods.
The propagation of Lamb waves in a structure results in the mode conversion of wave energy into different modes, and the changes in Lamb wave signals can be used to interrogate structural integrity [25, 26].
