Asymmetries in shaped charges
Abstract: This thesis concerns the effects of a select few asymmetries on a jet formingshaped charge. A Shaped charge(SC) is a formed explosive with metal liner thatcollapses under the detonation. The resulting shockcompression results in a jetof metal being shot forward in up 10km/s. The asymmetries that were modelledare bubbles in the LX14 high explosive, rust on the copper liner and offcenterdetonation. To simulate the SC the software IMPETUS afea is used. By replacingthe geometry with SPH particles instead of a mesh, a simulation with broadboundaries is possible which helps in the simulation of explosives. The resultsshowedthattheoffcenterdetonationcausedthebiggestdeviationinthejet. Therustcausedfragmentationinthejetbutasmallerdeviationandthebubblescausedvery little damage to the jet formation
