### Compressive strength of rocksPetroWiki

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

Compressive Strength. Compressive Strength is the stress in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.
