Resonant Fatigue Tester Machines are very often used for fatigue tests (S/N - curves) or in the fracture mechanics for pre cracking and crack propagation tests. This principle has many advantages compared to servo-hydraulic machines.
All types of tests with a Mid number of load cycles are beneficial applications for resonant testing machines because of the Mid testing frequency and as a result very short testing time as well as very low power consumption.
The additional advantage in comparison to servo-hydraulic systems with its actuators, valves and pumps is that maintenance is not required due to the wear-resisting construction.
