... is the critical stress intensity for fracture. Since then, there have been a number of other similar models in which fatigue is expressed as a function of mechanical properties alone, without making explicit reference to the material type. Dimitriu followed this principle to design a neural network model based...

Plane-strain fracture toughness is particularly pertinent in materials selection because, unlike other measures of toughness, it is independent of specimen configuration. In the plane-strain state, a material is at its lowest point of resistance to unstable...

... properties, the only readily available work (Ozelton et al., Ref 6 ) found that weld rework had no apparent effect on crack growth rates in D357-T6. Fracture toughness, on the other hand, was actually somewhat higher for the welded material. In general, welding produces a very fine microstructure...
