Prediction results show that under the pure tension, pure shear and tension-shear loads applied onto the original plane, Mode I fracture can occur on the sedimentary plane or on the plane of K_I(θ)_max. Mode I or Mode II fracture can occur under compression-shear load. The semi-circular bend (SCB) test results of anisotropic shale specimens with different ψ (crack inclined angle) and β (sedimentary plane angle) are in good agreement with the predicted results and can verify the validity of the modified K-ratio criterion.]]> Tue 29 Nov 2022 10:10:38 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49129 Fri 05 May 2023 11:53:17 AEST ]]>
