This relationship serves to provide the coulomb failure envelope within the Mohr-Coulomb Theory.

The prism maintains a 'critical taper', established in conformance with Mohr-Coulomb theory for the pertinent materials.

According to the Mohr-Coulomb theory of rock failure, large glacial loads generally suppress earthquakes, but rapid deglaciation promotes earthquakes.

The Mohr-Coulomb theory is named in honour of Charles-Augustin de Coulomb and Christian Otto Mohr.

Although it is now recognized that precise determination of cohesion is impossible because is not a fundamental soil property, the Mohr-Coulomb theory is still used in practice today.

By combining Coulomb's theory with Christian Otto Mohr's 2D stress state, the theory became known as Mohr-Coulomb theory.

Mohr-Coulomb theory is a mathematical model (see yield surface) describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress.

For undrained, constant volume shearing, the Tresca theory may be used to predict the shear strength, but for drained conditions, the Mohr-Coulomb theory may be used.
