RESEARCH

A combination of numerical analysis by the boundary element method and cracked ring specimens under diametrical loading is presented for determining the fracture toughness of anisotropic rocks under mixed mode I-II loading. The single domain BEM formulation which has been proofed with a good accuracy was used to calculate the SIFs of cracked anisotropic plate. A Taiwan marble with clear foliation was selected to conduct the cracked ring tests for measuring the failure load. The mixed mode fracture toughness with different material inclinations and crack angles can be determined the result of normalized SIFs which vary with the radius ratio (r), inclination of isotropic plane (y), and crack angle (b).
