[ 1 ] - A Novel Method for Ultrasonic Evaluation of Horizontal Defects Using Time-of-Flight Diffraction
Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. In this paper, a new ToFD method for evaluating horizontal planar defects is presented. The finite...
[ 2 ] - Resonance Ultrasonic Spectroscopy of a Nanofibrous Composite and Studying the Effect of Surface/Interface
Resonances are intrinsic characteristics of an elastic object, which are completely independent of the source of excitation. The appropriate utilization of the information contained within the resonance spectra and the identification of the resonance frequencies of the object can be used as a potent tool for material characterization. In this paper, a new mathematical model for the wave diffrac...
