Fatigue Strength Testing

Fracture mechanics and fatique behaviour

Measurement of high cycle and long life fatigue strength (HCF & LLF)
Fatigue testig with resonance frequency to simulate material behaviour and failure in real life application
High testing frequency (80 Hz)
Flexibility regarding sample geometry, load condition, material

Fatigue testing and Wöhler curves of standard and special samples, components
Short test duration thanks to resonator testing machine (RUMUL Testronic)
Detection of hardening and softening behaviour during the individual tests
Tests at room and increased temperature
Very small (<1 kN) to very large loads, at freely selectable load levels (tension/compression)

Test Procedure	Performance Parameters	Application
Fatigue test in the range of high cycle and long life fatigue	Standard samples and components up to 560mm component height Amplitudes: -100 to +100 kN Test frequencies up to 140 Hz Load ratio (R value) freely selectable	Creation of Wöhler curves, release dates for newly developed alloys
Fatigue testing at elevated temperature	Room temperature up to 900 °C	Materials at real operating temperatures
