A stability-based coupling approach was proposed to solve the fluid-structure interaction (FSI) problem encountered in the consequences modeling of pipe explosion. By applying this approach, the propagation of blast wave and the dynamic fracture of pipe were simulated synchronously. Element deletion technique and the bivariate failure criterion for high-strain-rate conditions were employed to model the dynamic crack growth of pipe. The simulated pressure histories in the pipe and final fracture patterns were compared and validated with the experimental data. The consequences of explosion in pipes were analyzed; the simulated peak pressures out of the pipe were compared with the results calculated by existing methods. Results show that the two predicted peak pressures with  considering the FSI effect are 83.1% and 62.2% of those without considering the FSI effect. The proposed method can more rationally predict the consequences of explosion occurring in pipes compared with semi-empirical models and traditional computational fluid dynamics (CFD) methods where the interaction between blast wave and pipe cannot be taken into account.
