Mechanical failure in rocks generally means either fracturing or permanent deformation as a result of compression. While many methods for calculating failure relationships exist, an initial measure of the compressive strength of reservoir rocks is still needed for use in those calculations.

Corinthian Granite 0.17%; Summit Granite 0.076%; 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

8. STRENGTH OF SOILS AND ROCKS 8.1 COMPRESSIVE STRENGTH The strength of a material may be broadly defined as the ability of the material to resist imposed forces. If is often measured as the maximum stress the material can sustain under specified loading and boundary conditions. Since an understanding of the behaviour in tension of a material such as steel is of great importance, the tensile

Rock Failure Topics • Compressive Strength • Rock Strength from Logs • Polyaxial Strength Criteria • Anisotropic Rock Strength • Tensile Strength. Key Points 1. When rock fails in compression, the compressive stress exceeds the compressive strength. 2. Even poorly-consolidated sands are characterized by a high coefficient of internal friction. Weak rocks are
