Fatigue testing
Confirming product designs and structures are safe and reliable
Fatigue testing is valuable for engineers to confirm their product designs and structures are safe and reliable. By understanding the fatigue behaviour of materials, engineers can design components resistant to fatigue failure.
Strain gauge load cells are vital for accurate fatigue testing. These devices measure the forces and stresses exerted on a test specimen during cyclic loading. The fatigue life of a specimen is the number of cycles it takes to fail. This data can be used to create stress-life or strain-life curves, which are used to predict the fatigue life of components under different loading conditions.
In a fatigue testing setup, fatigue-rated load cells and data logging instrumentation are used for testing materials, parts, or assemblies for weakness, and often ultimately to destruction. Load cells are typically attached to the specimen, or the test machine, and the cyclic loading is applied according to the test protocol.

Interface fatigue-rated load cells are vital for test and measurement projects in various industries, from aerospace and automotive to civil engineering and manufacturing. Manufacturers of test machines, aircraft, spacecraft, automotive components, consumer products, heavy machinery, bridges, energy production equipment, and industrial systems use our fatigue-rated load cells.
The fatigue rating of a load cell is a distinct specification, guaranteeing it has a service life of up to 100 million fully reversed load cycles at full rated capacity. They are typically integrated into testing machines or equipment.
The load cells continuously record the applied forces or stresses, allowing engineers and researchers to monitor how the material responds to repeated loading. By analysing the data from load cells, researchers can determine factors such as the material’s endurance limit, fatigue life, and stress-strain behaviour. This information is invaluable for optimising material selection, design, and manufacturing processes to enhance product performance and reliability while identifying fatigue and potential failure risks.
Interface has specialised in fatigue-rated load cells and their applications since our founding in 1968. The stringent discipline necessary to consistently produce actual fatigue-rated load cells is why Interface is known for this specialised load cell design and construction.
The LowProfile® configuration of our fatigue-rated load cell provides up to 100 million duty cycles. The gauged sensors in every load cell are individually inspected, tested, and certified to meet our rigid performance standards.
