Abstract

Todescribetheinteractionoftheexplosionfieldandthestructure,a2-DEuler-Lagrange couplingmethodwasdevelopedtocoupleaEuleriancodeandaLagrangiancode.TheEulerianfinite differentialcodecalledMMIC(multi-materialsincell)wasusedtosimulatethebehavioroftheexplosionfield. Andthedynamicfiniteelementcodewasusedtocalculatetheresponseofstructures.The Euler-Lagrangecouplingmethodwasusedtosimulatetheprocessofdeformationandpenetrationof anexplosion-drivedfragment.Thenumericalresultsindicatsthatthismethodhastheabilityofsimulatingtheproblemofexplosion- structuresinteration.
