Mechanical Property Analysis with Ultrasonic Phased Array

摘要：

In titanium alloy specimen and optic glass specimen, the velocity of ultrasonic longitudinal wave, transverse wave and quasi-rayleigh wave are measured with phased array transducer and signal processing. Because the measurement of the echos amplitude and phase is more accurate with phased array transducer than a single transducer, the measurement of the ultrasonic velocity is more accurate accordingly. The method proposed in this paper can also be used on the optic property evaluation of optic materials.
