【Abstract】 In order to study the influence of charging conditions on the failure characteristics of cylindrical metal containers, the damage characteristics of cylindrical metal containers were numerically studied by AUTODYN 3D nonlinear finite element program. The influences of the structure and the amount of the charge on the explosion damage characteristics of the device were discussed. The results show that the AUTODYN 3D nonlinear finite element program can effectively analyze the damage characteristics of the container. The charge structure significantly affects the initial position of the container damage, and the different charge amount has a significant impact on the failure morphology of the container.更多还原
