stress concentration factors

Stress concentration factors quantify how much local stresses increase around specific features like holes, notches, or sharp corners in a material. These features cause the stress to be higher in certain areas compared to the average stress across the part. The factor is a number that helps engineers estimate the maximum stress in such regions, ensuring designs account for potential weakness points and preventing failure. Essentially, it highlights where stress may be concentrated and requires careful consideration during design to maintain strength and durability.
