Методика измерения скоростей поперечных волн

Abstract

Physico-mechanical properties are important for a material. They can be determined by measuring the velocity of longitudinal and shear ultrasonic waves. Usual linear sizes o f objects for studies don’t exceed 5-7 mm. This precludes with use of classical methods of acoustic measurements that associated with the scanning o f a sample by moving the massive converter and broad beams o f waves. In this study we developed a special scheme for measuring the shear waves velocity with the additional medium delay.
