The strength values are comparable to determinations of uniaxial compressive strength tests of Westerly granite, which range from 130 MPa to 210 MPa (Heard and others, 1974). The slopes of best-fitting lines to the elastic portions of the stress-strain data from the strength experiments were taken for the values of Young's modulus.

Jun 04, 2015  Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but
