The centrally cracked Brazilian disc specimen has been used frequently in the past for investigating mixed mode I-II fracture toughness in rock materials. However, a review of the available test results reveals that the conventional fracture criteria like the maximum tangential stress criterion alwa
This paper is the second of a series of two papers dealing with the determination of the deformability, tensile strength and fracturing of anisotropic rocks by diametral compression (Brazilian test) of discs of rock. It is shown how a new formulation of the Boundary Element Method (BEM), proposed re
The flattened Brazilian disc specimen is proposed for determination of the elastic modulus E; tensile strength s t and opening mode fracture toughness K IC for brittle rocks in just one test. This paper is concerned with the theoretical analysis as well as analytical and numerical results for the fo
