“…Bubert et al [9] gave the equivalent elastic parameters of an accordion-like flexible honeycomb used as morphing aircraft skin. Zou et al [10] proposed a zero Poisson's ratio mixed cruciform honeycomb and studied the in-plane elastic constants, through theoretical calculation, numerical simulation and experiments. Liu et al [11] proposed a trapezoidal honeycomb with close-to-zero Poisson's ratio and the effects of geometric parameters on the elastic properties of the structure were studied.…”

A honeycomb is a kind of excellent lightweight structure and a honeycomb sandwich plate with zero Poisson’s ratio (ZPR) core is used widely in morphing structures. In this paper, a sandwich plate composed of a honeycomb core with zero Poisson’s ratio is analyzed for free vibrations and flutter under supersonic airflows. The equivalent elastic parametric formulas of the honeycomb core for zero Poisson’s ratio are proposed. The models are compared for their natural frequencies by theoretical and finite element methods respectively, which verifies the validity of the equivalent elastic parametric formulas and the model for the honeycomb sandwich plate with zero Poisson’s ratio. The influence of the geometric parameters of the honeycomb plate on the vibration frequencies is obtained. Three kinds of honeycomb cores, namely, regular hexagon, auxetic and hybrid with zero Poisson’s ratio, are compared through natural frequencies of the sandwich plate. It is found that the frequency of the zero Poisson’s ratio honeycomb sandwich plate is the second one when the other parameters are the same. The flutter of the honeycomb plate is analyzed by using the first order piston theory under supersonic flows. The critical flutter velocity of the plate is obtained, and the influence of geometric parameters of the honeycomb plate on the critical flutter velocities is obtained.

“…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.

“…A few of structures were shown can however achieve a Poisson's ratio of zero, like the SILICOMB, semi re‐entrant honeycomb (SRH) (see Figure c), hybrid cellular honeycomb which called as AUXHEX in ref., chevron honeycomb and its alternative configuration, accordion . More recently, some novel ZPR honeycombs were developed, including the hexagon‐plate combined structure, four‐pointed star configuration, and mixed cruciform honeycomb . As Grima and co‐authors showed in their work, zero Poisson ratio cellular structures have no synclastic or anticlastic behavior .…”

In this paper, a novel honeycomb is proposed by embedding a rib into every cell of the existing zero Poisson's ratio (ZPR) configuration, semi re-entrant honeycomb (SRH). Analytical model is developed to investigate the in-plane mechanical properties of the new honeycomb, and the resulting theoretical expressions are compared with the experimental tests and numerical results obtained from two different finite element (FE) models (3D beam model and 3D solid model), leading to a good correlation. FE analysis, analytical modeling, and experimental tests of the new honeycomb show that it can achieve ZPR effect in two principal directions. For further studies, parameters analyses are carried out to explore the dependence of the in-plane mechanical properties versus the geometric parameters. The results show that bending is the dominated deformation model when the new honeycomb is compressed along the x-direction, while stretch controlled in the ydirectional compression. It is remarkable that the new proposed honeycomb features superior specific stiffness and more flexible in mechanical properties tailoring compared to the other ZPR honeycombs in the literature. Given these benefits, the new honeycomb may be promising in some practical applications.
