Effects of Flaw Geometry on the Fracturing Behavior of Rock-Like Materials Containing Two Arch-Like Parallelogram Flaws

Table 4

Sketch of macro crack coalescence process in the specimens containing two parallelogram flaws with different angles under uniaxial compression (the light-blue lines represent the initial cracks and the dark-blue lines represent the new cracks emanating from the initial cracks).
