Stress vs Intensity - What
The stress intensity factor, $${\displaystyle K}$$, is a parameter that amplifies the magnitude of the applied stress that includes the geometrical parameter $${\displaystyle Y}$$ (load type). Stress intensity in any mode situation is directly proportional to the applied load on the material. If a very sharp … See more In fracture mechanics, the stress intensity factor (K) is used to predict the stress state ("stress intensity") near the tip of a crack or notch caused by a remote load or residual stresses. It is a theoretical construct usually applied to a … See more • Fracture mechanics • Fracture toughness • Strain energy release rate See more In 1957, G. Irwin found that the stresses around a crack could be expressed in terms of a scaling factor called the stress intensity factor. He found that a crack subjected to any … See more • Kathiresan, K. ; Hsu, T. M. ; Brussat, T. R., 1984, Advanced Life Analysis Methods. Volume 2.
