Numerical model of fracture growth in hydraulic re-fracturing

Oleg Yurievich Smetannikov, Yuriy Aleksandrovich Kashnikov, Sergey Gennadievich Ashikhmin, Artem Eduardovich Kukhtinskiy

Simulation of fracture propagation with FEM method generates the need of re-meshing to provide more accurate results. This raises a question of determining the direction and criterion of mesh modification. In the case of general-purpose…

Utilizing cylindrical and cubical specimens with edge notch to determine size-independent fracture quantities of rock materials

Ragip Ince, Erkin Eren

The compliance method was first applied to short rod specimens to determine the nonlinear fracture toughness of rock materials by ISRM (International Society for Rock Mechanics) in the 1980s. In this study, utilizing the techniques of the…
