FATIGUE TESTING USING AXIAL, SHEAR, ROTATING BEAM, ELEVATED TEMPERATURE HCF/LCF TESTING
Our Mechanical Fatigue Testing Lab utilizes cyclic loading (HCF-LCF) to predict the life of materials under fluctuating loads and temperatures. Determining fatigue life can support R&D efforts for new materials as well as prevent failures and recalls when used to ensure material properties.
Understanding a materials fatigue life is critical in a wide range of industries such as Aerospace, Medical Device and Oil & Gas to ensure safety and reliability as well as determine the longevity of a part or product.
IMR performs fatigue testing on:
- Coatings (coating shear)
- Composites (fiber-reinforced, ceramic-matrix)
- Nonmetallic/Metallic hybrid materials
- Finished products
Fatigue testing methods help manufacturers evaluate and validate characteristics of candidate materials. We have various frames designed to handle a wide range of loads and samples.

AXIAL FATIQUE TESTING
Axial testing methods help characterize mechanical properties of materials, both in static and dynamic conditions. The fatigue resistance measurement of materials subjected to direct stress for relatively large numbers of cycles measures material characteristics of axial loading profiles.
High-temperature fatigue testing analyzes materials engineered to perform in a wide range of temperature operating environments. Various alloys and composites are used in both aerospace and power generation applications, while experiencing operation environments with extreme temperatures.
ROTATING BEAM FATIGUE
The Rotating Beam test system uses a motor to rotate a shaft or a test specimen around its longitudinal axis. The specimen may be mounted either as a simply supported beam or as a cantilever. The resulting bending movement induces alternating tensile and compressive stresses of equal magnitude.
SHEAR FATIGUE TESTING
Shear Fatigue testing is performed on modern orthopedic and implant devices, which often incorporate porous coatings designed to promote bone infiltration for proper fixation of the implant. These critical coatings are subjected to shear stresses in normal use and the coating must not shear off under stresses.
