An intact solid cylindrical specimen of diameter 60 mm and thickness 30 mm is prepared from a Hoek-Brown rock material with m, 10. if the disc fails under a diametral compressive force of 7.8 kN as shown opposite, determine the brittleness index of the tested material based on stresses induced at the centre of the loaded specimen; i.e., the ratio of the material's compressive to tensile strength. Assume that the Hoek-Brown failure criterion is valid for the plane stress field condition developed at the centre of the specimen. 7.8 kN P
