Validation of a finite element model for fracture mechanics specimens [PDF]
, 2012 Single parameter formulations have shown to be insufficient to describe constraint effects in fracture mechanics specimens. This has lead researchers to a two parameter approach like the J-Q theory. In order to investigate constraint effects, the authors

An Estimation of Sufficient Impact Toughness for the Material of a Turbine Shaft [PDF]
, 2009 The fracture of a turbine shaft in the case of overloading can exhibit brittle or plastic failure, depending on the material properties, the turbine-shaft geometry and the form of loading. Usually, when the toughness increases, the stiffness of the shaft
