Repeated loading and unloading can create material fatigue, which can then lead to a fracture in the material – and to high costs and problems for you. This is why repeated stress tests and stress tests on materials are so important.
TÜV Rheinland offers material fatigue testing services delivered by trained and qualified mechanical engineers. We guarantee a proper test setup and also provide the expensive, complex equipment needed, saving you more money.
With material fatigue testing services from TÜV Rheinland, you can be sure of:
TÜV Rheinland’s approach to material fatigue testing is as follows:
Fatigue occurs when material is subjected to repeated loading and unloading. If the loads are above a certain threshold, microscopic cracks will begin to form at the surface. Eventually a crack will reach a critical size, and the structure will suddenly fracture.
The shape of the structure will affect the fatigue life significantly. Square holes or sharp corners will lead to elevated local stresses where fatigue cracks can initiate. Therefore, round holes and smooth transitions or fillets are important, to increase the fatigue strength of the structure. Samples of metals are tested in a fatigue testing machine that amplifies the fatigue process by rapid cycle testing over a period of time.
