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

Different from conventional materials, materials with negative Poisson's ratios expand
laterally when stretched longitudinally. Known as 'auxetic'materials, the effect means they …

This paper presents an analytical framework with a bottom-up multi-step approach to predict
the in-plane mechanical properties including the effective Young's modulus and Poisson's …

Artificially-structured materials with negative Poisson's ratio, also known as auxetics, have
been the focus of numerous studies over the past few decades. In this paper, using a group …

Abstract Conventional two-dimensional (2D) re-entrant auxetic honeycomb is one of the
earliest examples of auxetic metamaterials. Recently, plenty of 2D re-entrant honeycomb …

Following high profile, life changing long term mental illnesses and fatalities in sports such
as skiing, cricket and American football—sports injuries feature regularly in national and …

A series of novel bionic honeycombs (bio-honeycombs) are proposed by incorporating the
microstructure of the beetle elytra intersection unit into the regular hexagonal honeycomb …

Lattice structures have the potential for application in tensile conditions. However, limited
studies have addressed tensile behaviours of such structures and compared them with their …

Auxetic structures are a special class of structural components that exhibit a negative
Poisson's ratio (NPR) because of their constituent materials, internal microstructure, or …

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