Ultrasonic devices for gigacycle fatigue testing of materials

Anotace

The project is focused on the development of device for testing materials in the field of gigacycle fatigue. The device will load material at a frequency of 20 kHz. Thus, it will be possible to measure the extreme lifetimes of materials typically up to 10 billion cycles. The device reaches this limit in 6 days. These tests are unique and in great demand in current basic research. Two variants of equipment prototypes will be created: (i) for loading with a fully reverse push-pull cycle and (ii) for loading with an added static tension load component with a capacity of 20 kN.
