Abstract

The numerical modelling of an explosively formed camouflet is described and discussed. A uniform pressure was applied to the air/ground interface above a camouflet. Nine variations of the subgrade strengths were considered as nine separate load cases. The computer results showed that for load cases where there was no visual air/ground subgrade disturbance, the camouflet was difficult to detect. However, it was possible to identify the surface point above the centre of the camouflet. In load cases where loose fallback of the subgrade can be identified, increased surface deflections are evident and it is possible for an assessment to be made of the camouflet diameter.
