6, 1927, p. 189) are another example of the important conclusions which may be derived from a study of the interesting phenomenon of ultrasonic stationary waves. Velocities of sound in various ...
A possible method of detection is the use of ultrasonic waves in a manner analogous to the use of light waves in photoelasticity. An ultrasonic shear (transverse) wave entering a stressed solid ...
The rig uses a 60W ultrasonic transducer, operating at approximately 40 KHz, to generate a standing wave in combination with a reflector – essentially a rigid piece of material off which sound ...
