Time-frequency analysis of the dispersion of Lamb modes.
Accurate knowledge of the velocity dispersion of Lamb modes is important for ultrasonic nondestructive evaluation methods used in detecting and locating flaws in thin plates and in determining their elastic stiffness coefficients. Lamb mode dispersion is also important in the acoustic emission technique for accurately triangulating the location of emissions in thin plates. In this research, the...
متن کاملThe Application of Time-Frequency Transform in Mode Identification of Lamb Waves
This paper is focused on the problem of mode identification of Lamb waves in ultrasonic testing, and the principle and process of two time-frequency transform method, smooth pseudo Wigner–Ville distribution and two-dimensional Fourier transform, were discussed. The experimental work were carried out in aluminium plates, and the single and multimode Lamb waves were excited by 5MHz oblique incide...
متن کاملApplication of Wavelet Transform as a Signal Processing Method for Defect Detection using Lamb Waves: Experimental Verification
A Lamb wave-based crack detection method for aluminum plates health monitoring is developed in this paper. Piezoelectric disks are employed to actuate and capture the Lamb wave signals. The position of crack is assumed to be aligned with the sensor and actuator. Extraction of high quality experimental results of lamb wave propagation in a plate-like structure is considerably complicated due to...
متن کاملPathologies cardiac discrimination using the Fast Fourir Transform (FFT) The short time Fourier transforms (STFT) and the Wigner distribution (WD)
This paper is concerned with a synthesis study of the fast Fourier transform (FFT), the short time Fourier transform (STFT and the Wigner distribution (WD) in analysing the phonocardiogram signal (PCG) or heart cardiac sounds. The FFT (Fast Fourier Transform) can provide a basic understanding of the frequency contents of the heart sounds. The STFT is obtained by calculating the Fourier tran...
متن کاملMATERIAL CHARACTERIZATION USING HERTZIAN POINT CONTACT TRANSDUCERS Sample
Non-destructive Hertzian contacts are used to couple ultrasonic waves for characterization and defect detection in anisotropic solid pates. Spring loaded quartz rods bonded to PZT-5H transducers are used to form a point source point receiver pair and ultrasonic plate modes are excited and detected around 200 KHz with 50 dB signal to ratio at the receiving end. Measurements are performed on sili...
