High Cycle Fatigue (HCF) Testing

High cycle fatigue (HCF) is useful for materials that experience low applied forces and where deformation is primarily elastic in nature. HCF tests are usually force-controlled, and typically running to one million or more cycles.

Fatigue testing measures how cyclic forces will affect a product or material over time, using varying loads, speeds and environmental conditions. Our fatigue test methods, like high cycle fatigue, are useful for simulating specific scenarios and investigating real-world failures.

HCF Test Procedure

High cycle fatigue tests take place on an axial fatigue testing machine with a force-monitoring system. The sample is first machined, longitudinally polished and ground into cylindrical or flat test specimens with a uniform or hourglass gage section. Our Engaged Experts perform alignment and verification of the machined specimen before beginning any testing.

During an HCF test, samples experience frequencies ranging between 20 Hz and 100 Hz, depending upon material types and environmental conditions. Testing continues until specimen failure or until a predetermined number of cycles is reached.
