fracture plane
The fracture plane is the cut along which a material fails under mechanical stress. Its analysis provides insight into the cause of the failure.
Physical-Chemical Mechanism of Action
The fracture plane forms under mechanical overload or fatigue, as a response to the applied stresses. Atomic bonds break, and microscopic planar fractures occur.
Metallurgical Relevance & Risks in Welding
The position and orientation of the fracture plane can be indicators of the cause of failure in welded joints. Misaligned or too thin weld areas increase the risk of cracking and failure under load.
Workshop Practice & Instructions
When analyzing fracture planes, consider the following: check the stress states, weld quality, and material selection. Use microscopic examination methods to precisely determine the fracture plane.
