Threshold Stress Intensity Factor Range

The crack growth rate threshold is the point at which a crack continues to grow under repeated loading. It helps in setting allowable stresses and loads.

Physicochemical Mechanism of Action

The threshold for crack growth rate indicates how fast a crack grows under cyclic loading. It depends on material properties and loading conditions.

Metallurgical Relevance & Risks in Welding

A threshold that is too low can lead to rapid crack growth, which shortens the service life of components. It is important to consider this value when selecting material and loading.

Workshop Practice & Action Instructions

Determine the threshold through material testing and use it to plan for load conditions. At high stresses or temperatures, make sure crack growth stays under control.
