The second-order manifold method was used to simulate the dynamic tension split process of a flattened rock Brazilian disc subjected to shock loading through introducing a criteria for crack initiation and crack growth. The split process caused by a reflected tension stress wave was reproduced. The simulated phenomena are in good agreement with the experimental results. The dynamic equilibrium stress distribution also agrees with the calculated results by the finite element method. Researched results show that the manifold method is effective for the simulation of the dynamic failure process under shock loading.
