Observation of Bending Fatigue Testing of Metal Plate at Ultrasonic Frequency

A high-speed video camera was used to observe the movement of a metal plate vibrating while conducting a 20 kHz bending fatigue test. Previously, gaining an understanding of the overall movement of the test specimen required incremental repositioning of a displacement gauge, but with the high-speed video camera, it is possible to evaluate the movement of the specimen in a single observation process. Further, the possibility of determining the amount of movement of the specimen from captured images was also demonstrated.
