The energy absorption capacity of a novel dual-sub-fold Miura foldcore subjected to axial crushing

Materials & Design
A modified Miura foldcore geometry was developed by introducing sub-folds into the cell walls of a conventional Miura foldcore. Similar to other sub-fold Miura foldcores, stable plastic hinge lines were generated at sub-fold sites under the guidance of ...

Truss topology optimization for mass and reliability considerations—co-evolutionary multiobjective formulations

, 2011
The paper presents an approach for simultaneous optimization of structural mass and reliability in discrete truss structures. In addition to member sizing, the selection of an optimal topology from a pre-specified ground structure is a feature of the ...
