Cellular structures consist of foams, honeycombs, and lattices. Lattices have many
outstanding properties over foams and honeycombs, such as lightweight, high strength …

Rational design of artificial micro-structured metamaterials with advanced mechanical and
physical properties that are not accessible in nature materials is challenging and important …

Materials and structures with negative Poisson's ratio exhibit a counter-intuitive behaviour.
Under uniaxial compression (tension), these materials and structures contract (expand) …

A traditional aircraft is optimized for only one or two flight conditions, not for the entire flight
envelope. In contrast, the wings of a bird can be reshaped to provide optimal performance at …

DOI: 10.1002/aenm. 201500361 up to 20-times larger cooling powers per mass compared to
gadolinium (Gd), a benchmark magnetocaloric material, with comparable coefficient-of …

负泊松比材料和结构具有特殊的力学性能, 在单轴压力(拉力) 作用下发生横向收缩(膨胀).
其在抗剪承载力, 抗断裂性, 能量吸收和压陷阻力等方面比传统材料更有优势 …

Mechanical metamaterials have been attracting increasing attention for a wide range of
industrial applications, such as energy storage, biomedical, sensors, robotics, etc., owing to …

Tetra-chiral (TC) honeycombs are a type of auxetic materials showing negative Poisson's
ratio (NPR), which are promising for impact energy absorption. This study aims to analyze …

This work describes the theoretical, numerical and experimental in-plane and out-of-plane
elastic behavior of a class of anti-tetrachiral lattice structures with in-plane negative …

This work presents a novel negative Poisson's ratio honeycomb design composed by two
parts (a re-entrant hexagonal component and a thin plate part) that provide separate …
