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

Inspired by the vast amounts of investigations carried out on three-dimensional (3D) printed
structures and their recent accelerated developments, the present review paper …

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

As a branch of auxetics, the re-entrant hexagonal honeycomb has many superior
mechanical performances. However, most research focused on two-dimensional (2D) re …

Fractals widely found in nature possess amazing simple shape cell yet infinitely complex
macrostructures. Importantly, all fractals manifest a degree of self-similarity that provides …

In this paper, 3D printed lattice-filled multi-cell tubes, fabricated using chopped carbon-fiber-
reinforced polyamide, were proposed to modify the deformation modes and improve the …

Nature's bio-organisms are typically hybrid structures composed of hierarchical and
functionally graded micro-architectures, which are lightweight and of high mechanical …

Traditional auxetic metamaterials are characterized by negative Poisson's ratio but weak
stiffness. In this paper, a new auxetic metamaterial, re-entrant star-shape anti-chiral auxetic …

A bamboo bio-inspired method is developed to enhance the energy absorption capacity of
thin-walled tube for multiple load cases. Based on the simplified double-ring cross-section …

Thin-walled hollow structures capable of large plastic deformations are ubiquitously present
in sacrificial, high-capacity energy absorbers. A significant challenge in the field of structural …
