No matter, if your metals are copper, steel, or bronze, fatigue testing of metals, evaluates how metals behave under repeated cyclic loading. Fatigue testing helps engineers and researchers understand how a material’s mechanical properties change over time, especially when exposed to varying levels of stress. This is crucial in industries where metals are subjected to stressful conditions such as the aerospace and automotive industries.
Various international organizations such as ASTM and ISO provide guidelines and standards for conducting fatigue testing. Fatigue testing is conducted on specimens that have a specific geometry by subjecting the metal to cyclic loading that simulates real-world conditions.
How is fatigue testing performed?
The loading can be axial (tension and compression) or torsional (twisting or flexural). This cyclic loading induces alternating stress on the metal to see how the metal responds to different conditions. The number of cycles to failure is a critical parameter measured during fatigue testing. This is known as the fatigue life or endurance limit.
After the testing, the metal is examined to understand the failure modes. Fracture surfaces are often analyzed using microscopy. This can help make important decisions on where the metals can be used.
