“…Research on the NPR honeycombs is becoming abundant [4][5], while research on the ZPR honeycombs is relatively lagging. Most research on the ZPR honeycombs focuses on the 2D honeycombs, such as the semi re-entrant (SRE) honeycomb [6][7][8][9], accordion honeycomb [9][10][11], star-shaped ZPR honeycomb [12], reversed semi re-entrant (RSRE) honeycomb [13] and mixed cruciform honeycomb [14][15][16]. Some other research focuses on forming novel 2D ZPR honeycombs by combining multiple structures [17], adding structural thin struts [18] or changing the shape of structural thin struts [19][20][21][22][23].…”

A three-dimensional (3D) star-shaped zero Poisson's ratio (ZPR) honeycomb with cubic symmetry is proposed in this paper based on a twodimensional (2D) star-shaped ZPR honeycomb. Based on the Timoshenko beam theory and the energy method, the analytical formulas for the equivalent Young's modulus and the specific stiffness of the new honeycomb are obtained, which are verified by the numerical analysis and the experiments. The results show that the proposed new honeycomb has the ZPR effect in all three principal directions with the same equivalent Young's modulus. With this excellent property, the novel honeycomb is of good application prospect in some important fields, such as anti-collision facilities and wing morphing. In addition, the influence of the geometric parameters on this new honeycomb's elastic performance is further studied. The results show that the new honeycomb's elastic performance can be significantly improved by increasing either the thin struts' slant angle or the ratio of width to height of the thin struts. This study provides a new idea for the design of 3D ZPR honeycombs.

“…Olympio and Gandhi (2007, 2010) proposed such a geometry, called accordion design, as a core for morphing skins as shown in Figure 1(a). Based on accordion topology, several other designs have been proposed that mostly differ in the inclined rib’s geometry such as Figure 1(b) and (c) (Bubert et al, 2010; Chen and Fu, 2018; Huang et al, 2016; Liu et al, 2013; Rong and Zhou, 2017; Zou and Zhou, 2017). Chen et al (2015) investigated in-plane mechanical properties of three different ZPR accordion structures with hexagonal, re-entrant, and V-shaped ribs.…”

A novel cellular mechanical metamaterial called Fish Cells that exhibits zero Poisson’s ratio in both orthogonal in-plane directions is proposed. Homogenization study on the Fish Cells tessellation is conducted and substantially zero Poisson’s ratio behavior in a homogenized tessellation is shown by numerical analysis. Experimental investigations are performed to validate the zero Poisson’s ratio feature of the metamaterial and obtain force–displacement response of the metamaterial in elastic and plastic zone. A detailed discussion about the effect of the numerical model approach and joints on the structural response of the metamaterial is presented. Morphing skin is a potential application for Fish Cells metamaterial because of the integration benefits of zero Poisson’s ratio design. The structural integrity of the Fish Cells is investigated by studying the stiffness augmentation under tension and in presence of constraints on transverse edges. Finally, geometrical enhancements for improved integrity of the Fish Cells are presented that result in substantially zero stiffness augmentation required for morphing skins.

“…[67] Zero Poisson's ratio is also a mechanical feature that has attracted attention, [68][69][70] in particular for the development of structures with single radius curvature and unidirectional and 2D morphing configurations. [39,[71][72][73] In this study, we aim to explore and discuss the potential influence on the static, dynamic, and energy harvesting behavior of the [AEβ/AEθ] S architecture in symmetric angle-ply laminates architecture as piezoelectric composite energy harvesters.…”

Herein, the effect of symmetric carbon fiber composites laminates with angle-ply stacking sequences ([AEβ/AEθ ] S) in the design of composite piezoelectric energy harvesters (PEHs) is evaluated. Some of those specific stacking sequences also feature negative Poisson's ratio (NPR) or near zero Poisson's ratio (NZPR) through the thickness for ply angles θ < 45. Six different architectures with similar in-plane elastic modulus E 1 and different positive Poisson's ratio and NPR v 13 values are considered here. Finite element models are developed to understand the distribution of the voltage density of the laminates with the different stacking sequences and their bending properties. Experimental tests (three-point bending and vibration) are also performed. Both the simulations and the experimental results show that the PEH with the stacking sequences of near zero v 13 generate the highest power compared with the other composite energy harvesters. The maximum voltage frequency response function (FRF) happens at the fundamental resonance, and the PEH with near zero v 13 has also the lowest resonance frequency compared with the other stacking sequences.
