We revisit the scratch test within the framework of linear elastic fracture mechanics. In the analysis, we employ an Airy stress function approach to determine stresses and displacement in the vicinity of the scratch-blade-material interface, which serve as input for the evaluation of the energy rel

analysis of fracture toughness test data should provide dist~butional parameter estimates for the population of toughness predictions for use in integrity assessments. Standard statistical techniques are available which provide such information where the appropriate distributional form is normal but
A method is described for determining the fracture toughness of plain concrete from three-point bend specimens which accounts for the pre-peak crack growth that occurs upon loading. The fracture toughness so determined is shown not to depend on the size and geometry of the test specimen but on the m
