Shimadzu’s USF-2000A Ultrasonic Fatigue Testing System delivers powerful accelerated testing of materials’ fatigue strength at 20 kHz. The vibration is amplified by the booster and the horn; and transmitted to the test piece. It is possible to generate repeated stress on the test piece, perform uniform stress and testing; and to measure and obtain data at 109 to 1010 order of fatigue strength in days.
