A pipe bomb is an example of simple improvised explosive device （IED） that consists of a piece of pipe filled with explosive material and capped at both ends. To simulate the explosion of a pipe bomb and the damage it causes, a coupled multisolver approach based upon finite element and finite volume methods is applied. The numerical calculation presented demonstrates the ability of ANSYS AUTODYN to correctly simulate the threats of IEDs and provides insight into how the most significant physical phenomena affect the results.展开更多
