The K-R curve test provides valuable data about the toughness development as a crack is progressively propagated under an increasing applied stress intensity factor K. R-Curves and applied K-Curves are used to predict the critical stress intensity that will cause the onset of unstable fracturing....
The fracture toughness of a material can alter markedly depending on whether the elastic-plastic field ahead of the crack approximates to plane strain or plane stress conditions, much larger values being obtained under plane stress conditions as operate in thin sheets. The important and critical fac...
This page discusses fracture mechanics methods to predict failure of a cracked part. Topics include stress intensity factors, fracture toughness, Linear Elastic Fracture Mechanics (LEFM), and others.

The initial fracture toughness value (GICini) was deduced from the first loading curves. From Figure 6a,b, it can be observed that the fracture toughness improves with added PPOv and PPOv-FCNTs veils, while the PPOv-0.5% veil exhibits the highest toughness. From the first loading curve, ...

the weld metal properties were used to enable a case loaded to the stress level given to allow sensitivity studies on fracture toughness. The tensile properties of the weld metal were used, based on the stress–strain curve from specimen W01-76, producing a yield strength of 551 MPa and UTS...
