unconfined compressive strength | Oilfield Glossary

The unconfined compressive strength (UCS) is the maximum axial compressive stress that a right-cylindrical sample of material can withstand under unconfined conditions—the confining stress is zero It is also known as the uniaxial compressive strength of a material because the application of compressive stress is only along one axis—the ....
