Abstract Abstract: With the LS-DYNA non-linear and dynamic finite program, the dynamic expansion process of corrugated pipe, the major composition of energy conversion in submunition dispersing, under uniform internal pressure was numerically simulated, and its regular behaviors of dynamic response were achieved. The influences of various factors on deformation law of corrugated pipe are particularly investigated. The rule of coupled deformation for the corrugated pipe, the dispersion rule of submunition under internal pressure and external bullet cluster with the simulation of interior ballistic dispersing process was studied. The result of numerical simulation is elementarily accord with experiments.
