The method uses the elastic compliance calibration of fracture toughness test specimen geometry. Specimen compliance is measured with various sized three-point bend and compact tension specimens of granite. The experimental results show that the deformation behavior of the granite is significantly nonlinear and the specimen is successfully used to determine the effective Young's modulus rather than a fatigue precracked one because of the strong effect of fatigue loading on the specimen compliance.
