Abstract:

A series of transient non-linear dynamics computational analyses of the explosion phenomena accompanying the detonation of a 100g C4 mine buried in sand to different depths is carried out using the software package AUTODYN. The mechanical response of sand under high deformation-rate conditions has been represented using the modified compaction material model developed in our recent work 1. While the mechanical response of the other attendant materials air, gaseous-detonation products and AISI 1006 mild steel is accounted for using the material models available in literature. The results obtained specifically, the temporal evolution of the sand overburden shape and pressure at various locations in air above the detonation site were compared with their experimental counterparts for a 50wt-sand50wt.-clay soil obtained recently by Foedinger 2. The comparison revealed that the modified compaction material model for sand can account reasonably well for the magnitude spatial distribution and the temporal evolution of the dynamic loads accompanying detonation of shallow-buried mines in soils with various clay and water contents.
