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
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].
Sohn, 'Understanding a time reversal process in Lamb wave
propagation', Journal of Wave motion, Vol.
There is a demand on improvements, and numerical model of entire Lamb wave
system is needed.
In general it is not possible to avoid multimodality in Lamb wave
For an acoustic wave to propagate as a Lamb wave
(3), the material in which it propagates must be plate-like, i.
Hence, the signals could be analysed based on a Lamb wave
theory to quantitatively identify the damage types in the CFRP laminates.
0] Lamb wave
mode increases with frequency and thickness, and for [S.
The general papers describes a method for calculating the optical transmission properties of silicon wafers, investigate ultrasonic signal attenuation in syntactic foams filled with rubber particles, and develop a gold-on- PVDF interdigitated transducer for slow Lamb wave
The infinite number of Lamb wave
modes, which can exist within a plate is of two types.
The low attenuation feature of Lamb wave
makes it a perfect choice for guiding wave, which can travel up to long distances .
