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 FATIGUE TESTING
Critical for assessment of how materials behave under conditions mirroring those in structural components like beams and joints, axial fatigue testing applies tensile and compressive loads in cyclical patterns along a material's axis.
Applications: Metals, alloys, and structural materials.
Key Features: Varying cycle counts, custom load profiles, and accurate strain measurement.
HIGH-TEMPERATURE FATIGUE TESTING
Fatigue behaviors can vary in materials exposed to high temperatures. Cyclic loads applied to materials at elevated temperatures in order to assess performance in harsh environments, long term.
Applications: Aerospace components, exhaust systems, turbine blades.
Key Features: Real-time data collection, testing up to 1,200°C, thermal cycling.
ROTATING BEAM FATIGUE TESTING
Ideal for providing insights into a material's endurance limit, rotating beam fatigue testing is the rotation of specimens under cyclic bending stresses. Shafts and other rotating parts experience forces in real-world applications and durability and safety are critical.
Applications: Rotor components, power transmission, and automotive.
Key Features: Crack propagation monitoring, high-frequency cycling, continuous rotation at various speeds.
SHEAR FATIGUE TESTING
Shear fatigue testing predicts failure points when material's subject to repeated shear stress and sideways forces.
Applications: Composites, adhesives, bolted connections.
Key Features: Real-time strain data, multi-axis load application, customizable shear angles.
CRYOGENIC FATIGUE TESTING
Cryogenic fatigue testing is specifically for materials used in extremely low temperatures to ensure that they perform reliably.
Applications: Cyrogenic tanks, spacecraft.
Key Features: Resistance to brittle fracture, temperature-controlled chambers down to -196°C.
