SUZ rotating beam fatigue-banner


Our 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 validate material composition and properties. 

Understanding 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.

Shear Fatigue Testing Lab 

Coating Shear-closeup-300Shear Fatigue testing is used on modern orthopedic and implant devices, which often incorporate porous coatings designed to promote bone infiltration for proper fixation of the implant. These coatings are subjected to shear stresses in normal use and the coating must not shear off.

Rotating Beam Fatigue Lab

SUZ rotating beam fatigue-2-235-B

The Rotating Beam testing system  rotates a shaft or a test specimen around its longitudinal axis. The specimen is mounted either as a simply supported beam or as a cantilever. The resulting bending movement induces alternating tensile and compressive stresses of equal magnitude.

Axial Fatique Testing


Axial-torsion testing methods help characterize biaxial mechanical properties of materials, both in static and dynamic conditions. HCF direct stress measures fatigue resistance of materials that produces data that defines material properties.
