摘要：
Addressing the problem of spill of liquid fuel of fuel air explosive (FAE) with shell, this paper deduces variation relationship of fracture radius and fracture velocity based on continuity and motion equations of shell using the Taylor fracture criteria of cylindrical shells, and analyzes the correctness of the approximating process in detail. Furthermore, analytical solutions and numerical simulations for the liquid fuel spill process were obtained using Adomian's decomposition method (ADM) and the Runge-Kutta numerical method. Results show that both the numerical solution and the analytical solution based on ADM are closer to the result from experiments and computations from commercial dynamics numerical software.
