Honeycombs are ultra-light materials with outstanding mechanical properties, which mainly
originate from their unit cell configurations rather than the properties of matrix materials …

This study proposed a new bio-inspired hierarchical circular honeycomb (BHCH), mimicking
the hierarchical structures from wood. The mechanical properties and energy absorption …

In this study, the dynamic crushing behaviour and energy absorption characteristics of a
novel bio-inspired hierarchical multi-cell square (BHMS) tubes were numerically and …

This study proposes novel bio-inspired fractal multi-cell circular (BFMC) tubes for energy
absorption. The inner structures of the proposed BFMC tubes were constructed based on the …

In this study, numerical and theoretical investigations are carried out to study the crushing
behavior and energy absorption characteristics of bio-inspired hierarchical circular tube …

Both the concepts of bio-inspiration and hierarchy are found to be effective in enhancing the
crushing performance of tubes. In this paper, the bio-inspired hierarchical multi-cell …

Previous studies have shown that the multi-cell bi-tubular tubes exhibit superior energy
absorption compared to the multi-cell tubes. To further improve the energy absorption of the …

Aluminum foam-filled circular auxetic metamaterials were designed, fabricated and
investigated in this work. Firstly, the mechanical properties and deformation modes of the …

A tree-liked fractal method is proposed to develop a novel protective structure with great
energy absorption. Triangular, square and pentagonal tree-liked fractal structures are …

In recent years, the concept of hierarchy has been introduced into crashworthy design to
explore an ultralight energy-absorbing structure with outstanding mechanical properties. In …
