Our Mechanical Fatigue Testing Services Laboratories utilize cyclic loading (HCF-LCF) to predict the life of materials under fluctuating loads and temperatures. Determining fatigue life can support research and development efforts for new materials as well as prevent failures and recalls when used to ensure material properties. Understanding a material fatigue life is critical in the markets we serve, a wide range of industries, such as Aerospace Materials and Medical Device Testing, to ensure safety and reliability as well as determine the longevity of a part or product.
Fatigue testing methods help manufacturers evaluate and validate the characteristics of candidate materials. We have various frames designed to handle a wide range of loads and samples.To find out more about IMR's fatigue testing capabilities, request a quote, or click on the button below.
What Types of Materials Can Be Fatigue Tested?
•Metals •Finished Products •Composites •Polymers •Coatings •Non-Metallic/Metal Hybrids
Fatigue Testing Variables
Mechanical fatigue testing services ensure materials are tested properly with several variables to be considered. At IMR Test Labs we can assess the variables and apply them to our testing procedures in order to ensure an accurate and thorough analysis of the materials.
- Static Load vs. Oscillating Forces
- Behaviors and Scenarios of real-world use
- Temperature Exposure - Ambient vs. Thermal
- Fatigue Type - Compression / Tension / Bending
Mechanical Fatigue Testing Methods
AXIAL FATIQUE TESTING LABORATORY
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 LABORATORY
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 TESTING LABORATORY
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 LABORATORY
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.
