    Feb 01, 1996 Using these assumptions, the tensile strength of rocks can be estimated by 2 and 3 in terms of D, L, P and v. Our next step is to relate the tensile strength and the uniaxial compressive strength of the solid. We further assume here that there exists a fixed ratio between the tensile strength and the uniaxial compressive strength of rocks.

    Apr 01, 2004 The values of UCS and I s50 for the 188 sedimentary rock samples which we tested are given in Table 1.These are limestones, marly limestones, marlstones and sandstones. The UCS values ranged from 0.70 MPa for the calcareous-marly sandstones to 254 MPa for the quartzitic sandstones, representing extremely weak to extremely strong rock materials .The point load strength index values
