Abstract: This paper investigates the effectiveness of honeycomb sandwich structure in an MBT hull through a Finite Element Analysis based study. Two hulls, one with steel floor plate and the other with a honeycomb-sandwich floor plate made of aluminium alloy were modelled. Both these hull models were subjected to the same loads and boundary conditions and the resulting stress and deformation results are discussed and compared. It was observed that although the honeycomb sandwich floor plate did undergo higher stress and deformation compared to the steel floor plate, the values were within safe design limits. In addition to this, using these honeycomb structure would result in a substantial mass saving as found from the study. Finally, this paper also covers the practical difficulties associated with incorporating honeycomb structures in MBT hull construction and recommends future courses of investigation.
