Aiming at the fracture mechanics problem of rock material in petroleum engineering, fully illustrated theory of Debond technique is used to simulate and calculate crack propagation in ABAQUS software, and its fracture criterion based on fracture mechanics was introduced. The equivalent domain integral method of calculating stress intensity factor was introduced. The finite element model of rock fracture mechanics of type-I crack was established by Debond technique, and then static stress intensity factor of type-I crack at pure stress boundary condition was simulated and contrasted with analytic solution, which verified the rationality of numerical results. Finally, dynamic stress intensity factor of type-I crack was calculated with increase in loading and crack’s size and accurately predicted the critical stress in the two directions of the simulated rock. The results showed that ABAQUS Debond technique can simulate the fracture mechanics parameters of rock material, and it can effectively describe the fracture mechanics characteristics of rock.
