Experimental Study on Flaw Response in Inhomogeneous Media

摘要：

The objective of this paper is to predict the flaw response in an inhomogeneous solid medium. MultiGaussian Beam (MGB) model is used to represent the incident ultrasonic beam. The effect of ultrasonic attenuation and phase velocity dispersion due to grain scattering is included in the predictions. The effect of variation of mean diameter of the grains on the received voltage for different domain of interest is studied through the experimental results.
