The uniaxial compressive strength (UCS) is the maximum axial compressive stress that a rightcylindrical sample of material can withstand before failing. It is also known as the unconfined compressive strength of a material because confining stress is set to zero. Learn more in: Prediction of The Uniaxial Compressive Strength of Rocks Materials
