Measurement of ultrasonic velocity in viscoelastic materials using the wavelet transform
The measurement of the time propagation of ultrasonic pulses is a very important tool in ultrasonics. In this paper, a method based on the continuous wavelet transform (CWT) is presented. Experiments have been made on steel and acrylic, this last one as a case of viscoelastic material, where the CWT shows better properties than other digital methods.
