On a plate/surface wave mode selection criteria for .

The choice of specific modes while utilizing plate or surface waves, in the ultrasonic evaluation of layered structures, is extremely critical, especially if the purpose is to tune our sensitivity to particular types of imperfections. A direct approach based on the analysis of each individual mode, for particular geometrical configuration and frequency content, is .

In this study, fully bonded plates composed of aluminum plates (381 mm in diameter and 1.59 mm thick) and commercial epoxy adhesive were tested under shock wave loading. Full displacement field over the test plates was obtained by digital image correlation techniques, and full-field strains of the plates were computed by classical plate theory ...

As the f ⋅ d is 337.5 kHz mm, where f represents the center-frequency of the Lamb wave and d is the thickness of aluminum plate, the A 0 velocity is observed to be equal to 2.36 × 10 6 mm/s. The distance between the exciter and receiver has been depicted in Fig. 10, and in order to reduce interference from unrelated signals, the waveform ...

This paper presents an experimental and a simulation study of baseline-free damage detection in a stiffened aluminum plate by time reversed Lamb wave (TRLW). In this study, single Lamb wave mode ...

A laser operating at 532 nm is used to excite leaky guided waves on an aluminum plate immersed in water. The plate has a few artificial defects. An array of immersion transducers is used to detect ...

For aluminum plates, the shielding efficiency of electric field waves is very good in the whole frequency range; for plane wave shielding, the shielding efficiency in .

A0 and S0 modes of Lamb waves propagating in aluminum plate [3] The results of group velocity estimation The obtained the B-scan image of the asymmetric A0 and symmetric S0 modes propagating in aluminium plate of Lamb waves is presented in Fig.2. As can be seen they can be easily separated in the time domain due to different .

Li et al. successfully measured the thickness of inclined metal plate specimens and accurately determined the inclined direction of slope specimens by using EMAR technology and the n-wave compression and multiplication technique. The aforementioned research confirms that EMAR technology has been successfully .

No. 1 aluminum plate had no defect. The notch defect of 30 mm×20 mm×0.9 mm was machined on No. 2 aluminium plate and the other notch defect of 30 mm×20 mm×1.4 mm was machined on No. 3 aluminium plate. From the back side of the defect, the schematic of the test aluminium plate is shown in Fig. 9. Taking the location of .

In this study, a 500 500mm2 aluminum plate (1.6mm in thickness) with encastre boundary condition was considered. It is assumed that the structure and material properties are isotropic in the plate without any prestress. Any changes in the propagation characteristics of Lamb waves are therefore correlated with the exist-ence of damage only.

The theory of lamb waves was originally developed by Horace Lamb in 1916 to describe the characteristics of waves propagating in plates.48 Frequently, they are also referred to as plate waves. Lamb waves can be generated in a plate with free boundaries with an infinite number of modes for both symmetric and antisymmetric displacements .
