Fatigue Testing with Interface Load Cells

Engineers rely on fatigue testing to ensure the safety and reliability of their product designs and structures. By understanding how materials behave under repeated loading, engineers can design components resistant to fatigue failure.

Fatigue testing requires accurate and reliable force measurement. Interface uses ‘fatigue-rated’ as an exact specification that defines a special class of load cell design and construction. Interface fatigue-rated load cells are designed to withstand the rigors of repeated loading, which makes them ideal for even the most demanding high cycle count fatigue testing applications.

In a typical fatigue testing setup, Interface fatigue-rated load cells are attached to the test specimen or the test machine, and the cyclic loading is applied according to the test protocol. The load cells continuously record the applied forces or stresses, allowing engineers and researchers to monitor how the material responds to repeated loading.

By analyzing the data from Interface load cells, researchers and material engineers can determine the material’s endurance limit, fatigue life, and stress-strain behavior. This information is invaluable for optimizing material selection, design, and manufacturing processes to enhance product performance and reliability while identifying fatigue and potential failure risks.

The use of fatigue-rated load cells and data logging instrumentation is necessary for most test and measurement applications, particularly when materials, parts, or assemblies are tested for destruction. This is true because an accurate record of the forces at every moment of the tests is the only way an engineer can analyze the stresses that occurred in the moments just before the ultimate failure.

Profile of a Fatigue-Rated Load Cell

  • Design stress levels in the flexures are about one-half as high as in a standard LowProfile load cell.
  • Internal high-stress points, such as sharp corners and edges, are specially polished to avoid crack propagation.
  • Extraneous load sensitivity is specified and adjusted to a lower level than in a standard LowProfile load cell.
  • All Interface fatigue-rated load cells have a specified service life of 100 million fully reversed, full-capacity loading cycles.

No one can accurately predict exactly when the failure will occur, nor which part of an assembly will be the weakest link that eventually will fail. This is why high cycle count testing is the best way to measure fatigue life. To read more about fatigue testing and fatigue theory, consult Interface’s Load Cell Field Guide.

Fatigue Testing Applications
