2015-6-4  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

8. STRENGTH OF SOILS AND ROCKS

2009-2-23  compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.

Rock Strength - an overview ScienceDirect Topics

Rock strength is specified in terms of tensile strength, compressive strength, shear strength, and impact strength. In the context of fracture gradient, only the tensile strength of rock is of importance. The tensile strength of rock is defined as the pulling force, required to rupture a rock sample, divided by the sample’s cross-sectional area.
