The ability to significantly change the mechanical and wave propagation properties of a
structure without rebuilding it is currently one of the main challenges in the field of …

The ability to control Poisson's ratio of functional materials has been one of the main
objectives of researchers attempting to develop structures efficient from the perspective of …

Metamaterials are a type of groundbreaking engineered materials with unique properties not
found in natural substances. Lattice metamaterials, which have a periodic lattice cell …

In recent years, there has been a notable increase in the significance of active mechanical
metamaterials capable of being remotely manipulated through changes in external stimuli …

The effect of shearing on finite-sized auxetic and non-auxetic samples was examined
through finite element simulations. It was shown that when shear was applied in a manner …

The design representations of lattice structures are fundamental to the development of
computational design approaches. Current applications of lattice structures are …

Structural metamaterial with negative Poisson's ratio often has low stiffness due to its porous
structure. For engineering applications, the various strategies have been developed to …

Inspired by butterfly, a bio butterfly-shaped auxetic metamaterial (BSAM) was recently
proposed in which the unite cell of BSAM was designed based on silhouette of a butterfly …

This is the fifteenth volume of I Physica Status Solidi B i focussed on materials and models
showing negative Poisson's ratio (PR), which are often called auxetics, and other systems of …

In this article, a three‐dimensional (3D) auxetic system is designed by linking layers of
rotating squares with torsion springs. The orientation of the rotating squares in the different …
