For the fatigue crack growth simulation in Regime III, the constant loading amplitude is applied with [F.sub.max] = 24 kN at R = 0.1, which corresponds to the initial stress intensity factor range [DELTA] [K.sub.i] = 76 MPa [m.sup.1/2].
The whole stress intensity factor of breakdown pressure is divided into three parts: [K.sub.1] is the stress intensity factor of in situ stress; [K.sub.2] is the stress intensity factor of borehole stress; and [K.sub.3] is the stress intensity factor in pore stress.
