Vibration Crack
A vibration crack forms due to repeated high mechanical loads and leads to fatigue failure. Resonance or uneven mass distribution are common causes.
Physical-chemical mechanism of action
Vibration cracks are caused by repeated, high mechanical loads that push the material beyond its fatigue limit. These loads can be caused by resonance phenomena or uneven mass distribution.
Metallurgical relevance & risks in welding
Vibration cracks lead to fatigue failure and can cause component failure and safety issues. They are particularly dangerous in high-load applications or components with large load diameters.
Workshop practice & instructions
To avoid vibration cracks, components should be designed optimally to minimize resonance phenomena. This includes even mass distribution and the use of stable materials. When manufacturing components, care must be taken to avoid uneven stresses that could lead to vibrations.
