Compressive strength of rocks  PetroWiki
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.

STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1 ...
In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Furthermore, if a rock mass is cut by directional joint sets , the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under consideration.
