... as well as bedding dip. The results show that the increase of the anisotropy of Young's modulus, Poisson′s ratio and horizontal in-situ stress induces a reduction of the FIP. While an increase of tensile strength ratio T v /T h and bedding dip will increase the FIP. It is concluded that the influence...

... and by considering it, crack initiation stress observed in the laboratory can be captured (∼ 40% of UCS). BACKGROUND Natural rocks and man-made granular and fibrous composites display bi-modularity when subjected to compressive and tensile stresses. In rocks, the tensile Young's modulus is typically less than...
