Abstract:

A new blast code, LociBLAST, has been coupled with the commercial structural dynamics package LS-DYNA to provide a fully-coupled simulation strategy for predicting the effects of blast on a ground vehicle. LociBLAST is a fully-conservative, computational fluid dynamics code with the capability to model soil and blast using a multispecies formulation with advanced equations of state. The two-way coupling between LociBLAST and LS-DYNA provides a robust mechanism for predicting the blast-induced deformation of structural elements with no topology changes. The efficacy of the resulting software is demonstrated by comparisons of predicted deformations for a constrained plate with experimental data. Results are also presented for a notional hull subjected to the effects of detonation of a buried IED.
