Stressintensiteitsfactoren
Stressintensiteitsfactoren, often abbreviated as K, are a concept in fracture mechanics used to describe the intensity of stress at the tip of a crack in a material. When a material contains a crack, the stress is not uniformly distributed. Instead, the stress concentration at the crack tip becomes very high and theoretically infinite in ideal elastic models. Stress intensity factors provide a way to quantify this stress singularity in a physically meaningful manner.
The value of the stress intensity factor depends on the applied stress, the size and shape of
The primary use of stress intensity factors is in predicting fracture. If the stress intensity factor reaches
