Simulation of Blast and Fragment Loading Using a Coupled Multi-Solver Approach

Simulating blast and fragment loading simultaneously in a single computation requires the combined use of multiple states of the art solvers. 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 lEDs and provides insight into how the most significant physical phenomena affect the results.
