This study focuses on the design, behavior and experimental analysis of a novel
metamaterial, consisting of an asymmetric auxetic three-dimensional structure (AATS) …

In this research, a three-dimensional auxetic configuration based on a known re-entrant cell
is proposed. The 3D auxetic cell is configured from a new design parameter that produces …

This work aims to study the influence of the material and geometric parameters that
characterize re-entrant hexagonal honeycomb auxetic structures in the maximum transverse …

The use of metamaterials is a good alternative when looking for structures that can withstand
compression forces without increasing their weight. In this sense, using nature as a …

Abstract Based on Euler-Bernoulli beam theory, the equivalent elastic properties of auxetic
cellular structure with irregular configurations are derived by using the representative unit …

Additive manufacturing (AM) has many advantages over traditional manufacturing
technologies as it allows the fabrication of lattice structures with complex designs and …

Auxetic materials have recently attracted particular interest due to their wide range of
