Energy absorption mechanisms of hierarchical woven lattice composites

Compressive and bending behaviours of wood-based two-dimensional lattice truss core sandwich structures

“…After reaching the peak load, the compression test curves slowly a decrease with a relatively large displacements. In view of this, the wood-based 2D lattice truss core sandwich structures demonstrate good energy absorption capability [2,40], which is important for the safety of wooden construction.…”

Hybrid design and energy absorption of luffa-sponge-like hierarchical cellular structures

“…Through hierarchical topology, structures usually get ultralight and possess greater anti-buckling ability [5] and more excellent energy absorption [6][7][8][9]. Research group of Fan et al [6][7][8][9] have made various hierarchical lattice composite structures and revealed their priority in SEA. Sun.…”

“…et al [6] found the hierarchical lattice tube have hierarchical fold mechanism which enhances the SEA of the tube. Woven sandwich wall in the honeycomb induces stable deformation plateau for hierarchical composite honeycombs [7][8][9].…”

Dynamic response of functionally graded cellular materials based on the Voronoi model

“…Considerable experimental and numerical studies have been conducted to investigate the dynamic behavior of cellular materials [1][2][3][4][5][6][7][8][9][10][11][12]. The deformation, crushing stress and energy absorption as well as the cell geometric topology of the uniform cellular materials have been studied systematically.…”
