For a planar, clean (no infilling) fracture, the cohesion is zero and the shear strength is defined solely by the friction angle. The friction angle of the rock material is related to the size and shape of the grains exposed on the fracture surface....
The unconfined compressive strength (UCS) of sedimentary rocks is a key parameter needed to address a range of geomechanical problems ranging from limiting wellbore instabilities during drilling, to assessing sanding potential and quantitatively cons...
In-situ stresses: Overburden and Minimum/Maximum Horizontal Stresses. Underground rocks and sediments are subjected stresses, the principal ones being: Vertical stress Minimum horizontal stress Maximum horizontal stress It is critical to identify the...
Tensile strength is a measurement of the force required to pull something such as rope, wire, or a structural beam to the point where it breaks. The tensile strength of a material is the maximum amount of tensile stress that it can take before failur...
