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.
High Cycle Fatigue Testing 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.

Aerospace High Cycle Fatigue Testing
We provide indispensable High Cycle Fatigue Testing (HCF Testing) of engine airfoil and gas turbine components for service life limit analysis, simulating high vibrations conditions of airfoils during operation.
Our Fatigue Testing Methods
Element performs a variety of fatigue tests, including high cycle fatigue, low cycle fatigue, and specialized programs on a range of metals and alloys, polymers and components.
Thermal Paint Testing
Thermal Paints are used to provide full surface temperature measurement within concealed areas. They present visual evidence of peak temperatures and isothermal distributions, with temperatures indicated by colour changes or surface texture, that occur at one or more distinct temperatures.
The paints provide temperature distributions for component surfaces that are difficult to obtain such as aero engine turbine blades, vanes, segments, combustors, or rotating components within harsh environments.
Rolls-Royce have been using thermal paints for over 80 years There are a range of paints and services available that include:
- Guidance and recommendation on test planning
- Paint application
- Test design and support
- Post-test analysis
- Results can be displayed through high resolution photos, 3D models, or 3D and 2D temperature embedded images
- Technical report detailing test specification, results and conclusions
