The Strength Criterion for Rocks Under True Triaxial Stress
Procedia Structural Integrity, 2021 Abstract A new criterion has been developed for the strength of rocks in the condition of true triaxial stress. The criterion parameters are calculated based on the results of a complex determination of the ultimate strength, which includes uniaxial tensile, uniaxial compression and biaxial compression.
