Given that the confining strain increases, the increase in resistance to longitudinal crack propagation brings about a gradual transition of shale failure method from longitudinal to inclined shear failure that demonstrates an escalation in rock plasticity. Once the confining force reaches 30 MPa, there are still community shear microcracks https://tryhere86327.wikipublicist.com/6237999/the_best_side_of_wellbore_breakout_analysis
