Auxetics are a class of structural metamaterials with a negative Poisson's ratio. In
comparison to conventional structures, auxetic structures are proven to exhibit several …

With the swift advancement of aerospace, shipbuilding and engineering, the significance of
sandwich structures with cellular cores is becoming increasingly prominent due to their multi …

Most natural (or biological) materials possess chiral and hierarchical properties, thus can
exhibit outstanding mechanical properties, such as shear resistance, vibration attenuation …

This paper presents for the first time two types of metamaterials based on the fragmentation–
reconstitution of rotating units in order to produce Poisson's ratio discontinuity at the original …

In this paper, a novel auxetic structure with rotating squares with holes is investigated. The
unit cell of the structure consists of four units in the shape of a square with cut corners and …

In this work, the 3D circular curve transversal-isotropic auxetic structure (3D-CCTAS) is
designed based on a six-fold rotation symmetry in space and combines circular-curve and re …

The influence of lattice structural design on the mechanical property has been abundantly
investigated, however, the effect of material on the load-carrying performance and energy …

NPR structures possess unique mechanical characteristics rendering them attractive for
various engineering applications. However, their low in-plane stiffness limits their structural …

In order to improve the combat effectiveness, stealth and safety of the marine structures, we
design and fabricate the multilayer gradient composite lattice sandwich panels (MGCLSPs) …

Composites with negative Poisson's Ratio (NPR), also known as auxetic composites, are of
great interests due to excellent properties. Auxetic composites of various types have been …
