Fatigue testing characterizes material or component behavior during cyclic loading. Our test machines can help test cyclic loads for vital properties, such as fatigue failure, fatigue limit, and fatigue life.
What is fatigue testing?
A fatigue test measures how cyclic forces will affect a product or material over time, by analyzing various sizes of cyclic loads in our test machines, under different speeds and environmental conditions, we can create predictive patterns for material behavior. While a large portion of fatigue tests are performed to plot stress (S) against the number of cycles to failure (N) (also known as an S-N curve), they can also be useful for simulating specific scenarios and investigating real-world fatigue failures.
Why is fatigue testing important?
Understanding fatigue properties is one of the most crucial elements of research and development, product safety, and material verification programs. It's important to test your materials & products to understand their performance, fatigue limit & fatigue life.
What is the purpose of fatigue testing?
Some products, such as medical devices, must conform to rigorous international standards for endurance properties. Other products, such as industrial components and consumer goods, often see manufacturers and testing companies working together to develop customized fatigue testing methodologies suited for the specific product’s application and end-use environment.

Fatigue & Fracture ToughnessÂ
Fatigue in metals caused by cyclic loading progressively damages a localized area of a structure, eventually leading to the formation of cracks. Once a crack is formed, it will grow with each application of load.

ºÃÉ«TV 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.
ASTM E606 Low Cycle Fatigue (LCF)
LCF testing is used for applications where materials are subject to extremely high mechanical stresses, and where plastic deformation is likely to occur.
ASTM E466 High Cycle Fatigue (HCF)
High cycle fatigue is used for materials that experience low applied forces and where deformation is primarily elastic in nature.

Rotating Beam Fatigue
Rotating beam fatigue is another testing method which is utilized to generate high cycle fatigue curves at a higher frequency than traditional HCF methods with single or multi-point bending stresses.
Stress Rupture Testing
ºÃÉ«TV offers stress rupture testing to understand the sudden and complete failure of a material under stress. Loads may be applied by tensile bending, flexural, biaxial or hydrostatic methods.
Creep Testing
Measuring load over an extended period of time, creep testing programs use continuous load and elevated temperature to test for eventual material failure.
