A two-stage structural optimisation and thermal discretisation of non-convective structured insulators: applications in granular-solid structures by additive manufacturing technology

posted on 2018-07-18, 16:26 authored by Da-Zhe (Bertrand) NgimA systematic design procedure for characterising the strength and insulation requirements
of a modular unit structure from additive manufacturing has been presented. The
proposed 'two-stage' method consists of structural optimisation and thermal
'discretisation', through use of the Metamorphic Development (MD) and Discretisation
by Partitioning Method (DbPM), respectively. A structural layout optimisation method
of a consolidated granular-solid structure for strength requirements is demonstrated. The
reliability of the layout optimized design solution tested using experiments and finite
element analysis (PEA) are reproduced with reasonable accuracy. Layout optimisation
yielded 40% savings in build material, whilst satisfying the targeted deflection. [Continues.]
