Modeling of Complete Stress-Strain Curves and Time-Dependent Behaviors of Rocks under Uniaxial Tension

Tensile stresses likely occur in the rock masses around large or intricately shaped caverns. Hydraulic fracturing for oil, gas, or geothermal development requires a deep understanding of crack extensions under tensile stress. Computer simulation is helpful for the estimation of such deformation and failure of in-situ rocks and requires a mechanical model representing complex rock behaviors under tension. The authors’ research group previously...
