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.
