The subsequent analysis uses fracture mechanics: we calculate the stress intensity of this notch-root crack and use this to predict failure. The method has been applied quite widely to problems in brittle fracture and in fatigue, using Kc or ΔKth as the critical stress intensity parameter, ...
The crack propagation is expected to follow rules of fracture mechanics with the corresponding methodology described in the chapter. Expressions for energy release rate due to steady-state crack propagation are presented. The obtained expressions contain normalized crack opening and sliding displacements, ...

the failure loads predicted by the Griffith energy based criterion are infinitely high, while the failure loads from a strength-of-material approach tend to be zero. therefore, resolving this contradiction requires a different approach. Finite Fracture Mechanics as proposed by Hashin (1996) addresses...
