Relationship between Brittleness Index and Crack Initiation Stress Ratio for Different Rock Types
Brittleness and crack initiation stress (σci) are important rock mechanical properties and intrinsically related to rock deformation and failure. We establish the relationship between σci and uniaxial tensile strength (σt) based on the Griffith stress criterion of brittle failure and introduce britt...
