Cellular structures are generally assembled with face sheet plies in their application. It is necessary to understand the influence of assembled plies on deformation and energy absorption before using textile composite cellular structures in engineering design. In this paper, effects of ply assembly, outer ply material, outer ply thickness, and loading area on energy absorption and deformation of the applied structure including cellular structure and face sheet plies are investigated. Three-dimensional finite element analyses are carried out employing orthotropic mechanical properties of the applied materials, textile composite, wood, E-glass, aluminium alloy 2024-T3 and unidirectional fiber-epoxy composite T-300. The predicted results show that deformation and distributed strain energy density of both outer and inner surfaces of the applied structure are significantly affected by ply assembly, outer ply material, outer ply thickness, and loading area.
