Rotating beam fatigue testing generates higher frequencies than traditional high cycle fatigue (HCF) methods. Our testing services provide critical data about coatings and metallic surface treatments to ISO 1143, ASTM F1160 standards, or bespoke methods to meet your test requirements. 

Rotating beam fatigue testing

Rotating beam fatigue testing is a mechanical test method used to evaluate the fatigue properties of materials. In this test, a beam specimen is subjected to cyclic loading, which induces repeated bending causing failure over time. The specimen is mounted on a rotating apparatus, which allows for the cyclic load to be applied at constant amplitude and frequency.

During the test, the beam specimen is rotated at a constant speed while a loading force is applied to it. The force causes the beam to bend, and as the beam rotates, it undergoes cyclic bending stress that can induce fatigue failure.

The data generated can be used to design and optimize materials for use in applications where fatigue failure is a concern, such as the Aerospace and Automotive industries.


Rotating beam fatigue test preparation and process

Before the test, our labs grind and polish samples to ensure the most accurate results. Depending on the goal of your project, testing is either run to a set number of cycles or to failure. If the specimen fails, our experts can provide failure analysis to determine what can prevent future occurrences. 


Test methods ISO 1142 and ASTM F1160

In addition to our ISO 1143 rotating bar bending fatigue testing and ASTM F1160 shear and bending fatigue test programs, our experts can assist in performing custom and unique rotating beam fatigue testing methods.


The Element advantage

We assist in all stages of the process, from machining and polishing samples to interpreting test results and analysis of failure. With years of fatigue testing experience, we can assist with any project, no matter how complex.
