Fatigue Fatigue Striations
Fatigue Striations are microscopic ridges on the fracture surface of a fatigue crack that indicate the load history. Analyzing them helps in reconstructing load histories.
Physicochemical Mechanism of Action
Fatigue Striations form due to repeated loading of a material under stress. With each load cycle, microscopic stripes form on the fracture surface, mapping the progress of the fatigue process.
Metallurgical Relevance & Welding Risks
Analyzing Fatigue Striations can help determine the actual load history of a component. Misinterpreting or ignoring these structures can lead to inaccurate conclusions and missed opportunities to improve load-bearing capacity.
Shop Practice & Action Guidelines
Use microscopic examinations to identify Fatigue Striations on fracture surfaces. Carefully document the number and orientation of the stripes. This information is crucial for reconstructing load histories and optimizing the material and welding process.
