2. Even though the cubic law is based on the ideal parallel-plate assumption instead of representing the real fracture with roughness, it can be still employed as a suitable approximation method for large aperture areas (Witherspoon et al., 1980). However, additional stress (normal) (Gale ...
Graph theoryspatial analysishydraulic fracturingDrilling induced fractures are generated when excessive stresses around a borehole cause tensile failure of the wellbore wall. If stress concentrations are great enough, compressive failures can form in the region surrounding the wellbore, leading to wellbore ...
The geometrical stress concentration factor (Kt) determines the effect of the changes in the geometry on the local stress. It is then used as a multiplier to the applied stress to estimate the maximum stress at the point of the stress riser. The magnitude of Kt depends on the size and sha...

Crack branching becomes more prevalent as the sample approaches 30°, at which point fracture paths going up or down at a 30° angle are equally likely due to the symmetry of both being zigzag edges. A comparison of stress–strain curves between our data and the example from the literature...

3a) accounts for the effect of the neighborhood of a crack tip on the stress concentration/redistribution and, hence, the crack advance. It is implemented as a custom message-passing graph convolution44. The temporal component (Fig. 3b) incorporates any pertinent history effects of the process ...
Apertures ranged from 250 down to 4 μm, which was the minimum size that could be attained under a normal stress of 20 MPa. The cubic law was found to be valid whether the fracture surfaces were held open or were being closed under stress, and the results are not dependent on rock ...
