Poisson's ratio had long been considered to be an intrinsic material property, confined within
a narrow domain and governed solely by the geometry of interatomic bonds. Materials with …

Materials with negative Poisson's ratio attract considerable attention due to their underlying
intriguing physical properties and numerous promising applications, particularly in stringent …

In comparing a material's resistance to distort under mechanical load rather than to alter in
volume, Poisson's ratio offers the fundamental metric by which to compare the performance …

In this paper, two new 2D re-entrant topologies with negative Poisson's ratio are presented
and their mechanical properties (Poisson's ratio and energy absorption capacity) are studied …

Hybrid organic-inorganic perovskites (HOIPs) have attracted significant attention in recent
years attributed to their outstanding physical properties and striking application potentials in …

In this paper, a novel three-dimensional (3D) unit cell structure with butterfly-like perforations
was designed, and negative Poisson's ratio and tunable stiffness were achieved in such a …

The Poisson's ratio is a fundamental measure of the elastic-deformation behaviour of
materials. Although negative Poisson's ratios are theoretically possible, they were believed …

We study the temperature dependent elastic properties of Ba0. 8Sr0. 2TiO3 freestanding
membranes across the ferroelectric-to-paraelectric phase transition using an atomic force …

Two-dimensional hierarchical re-entrant honeycomb structures were designed and the
mechanical behaviors of the structures were studied using a finite element method …

A novel unit cell structure with re-entrant hollow skeleton was designed and its Poisson's
ratio was studied using the finite element method (FEM) as a function of the geometric …
