Rock Failure Topics  Stanford University
1. When rock fails in compression, the compressive stress exceeds the compressive strength. 2. Even poorlyconsolidated sands are characterized by a high coefficient of internal friction. Weak rocks are weak because they lack cohesion. 3. Intermediate principal stress (S 2) probably influences compressive strength only at very great depth. 4.

Compressive strength  Wikipedia
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate.In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). In the study of strength of materials ...

ASTM Test Results  Select Stone
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.

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.
