Different from conventional materials, materials with negative Poisson's ratios expand
laterally when stretched longitudinally. Known as 'auxetic'materials, the effect means they …

Auxetic textiles are intriguing materials with unusual capabilities. These materials exhibit
negative Poisson's ratio with extraordinary performance in toughness, resilience, shear …

Using first-principles calculations and evolutionary structure search, we predict a series of
kinetically and thermodynamically stable Li x B y monolayers. While the Li 2 B 2 monolayer …

Silicon dioxide or silica, normally existing in various bulk crystalline and amorphous forms,
was recently found to possess a two-dimensional structure. In this work, we use ab initio …

This paper reviews 2D auxetic models, including 3D deformation models with 2D auxetic
behavior, from mechanism perspective instead of geometrical perspective. On this basis …

Auxetic materials are highly desirable for advanced applications because of their negative
Poisson's ratios, which are rather scarce in two-dimensional materials. Motivated by the …

Negative Poisson's ratio (NPR) in auxetic materials is of great interest due to the typically
enhanced mechanical properties, which enables plenty of novel applications. In this paper …

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 …

A partially-auxetic metamaterial is introduced, inspired by the Maltese cross. Each unit of this
metamaterial consists of a pair of counter-rotating equal-armed crosses, which is …

Metamaterials with strain-independent negative Poisson's ratio (NPR) and Young's modulus
are essential for the applications with extreme loading conditions. However, strain …
