Abstract The peridynamic method had great advantages in solving the problem of crack propagation in rock material due to its nonlocal characteristics. However, the method also faced problems such as zero-energy mode and boundary effects. In order to solve the above problems, the paper first proved that the non-ordinary state-based peridynamic(NOSB-PD)method was equivalent to the Galerkin weak form with nodal integral scheme. The equation of solving the deformation gradient F in NOSB-PD method was extended to a more general form, namely the peridynamic differential operator(PDDO)approximation. Since the PDDO had the same displacement approximation with the reconstruction kernel particle method(RKPM), this paper compared the difference between the two methods in the approximations of displacement derivatives in detail. The RKPM-PD coupling method with higher accuracy was proposed in the paper. Several numerical examples proved the accuracy of the new method in predicting the dynamic crack propagation in rock.
