Fracture Process Zone Evolution in Tight Sandstone Under Crack-Parallel Stress: A DIC Study
Crack-parallel stress modifies the near-tip stress state and may influence the development of the fracture process zone (FPZ) in rock. However, the spatial and temporal evolution of the FPZ during hydraulic fracturing cannot be reconstructed from the final fracture morphology alone. In this study, visual hydraulic-frac...
