This thesis concerns the effects of a select few asymmetries on a jet forming shaped charge. A Shaped charge(SC) is a formed explosive with metal liner that collapses under the detonation. The resulting shock compression results in a jet of metal being shot forward in up 10km/s. The asymmetries that were modelled are bubbles in the LX14 high explosive, rust on the copper liner and off center detonation. To simulate the SC the software IMPETUS afea is used. By replacing the geometry with SPH particles instead of a mesh, a simulation with broad boundaries is possible which helps in the simulation of explosives. The results showed that the off center detonation caused the biggest deviation in the jet. The rust caused fragmentation in the jet but a smaller deviation and the bubbles caused very little damage to the jet formation.
