= Stress intensity factor
{wiki=Stress_intensity_factor}
The Stress Intensity Factor (SIF) is a fundamental concept in fracture mechanics that quantifies the stress state near the tip of a crack in a material. It provides a measure of the intensity of the stress field around the crack tip and is essential for assessing the risk of crack propagation in structural components under load. The SIF is denoted by \\( K \\) and varies depending on the loading conditions, crack geometry, and material properties.
