Honeycombs are ultra-light materials with outstanding mechanical properties, which mainly
originate from their unit cell configurations rather than the properties of matrix materials …

Materials and structures with negative Poisson's ratio exhibit a counter-intuitive behaviour.
Under uniaxial compression (tension), these materials and structures contract (expand) …

The surge of interest in so-called “designer materials” during the last few years together with
recent advances in additive manufacturing (3D printing) techniques that enable fabrication …

Over the last three decades but more particularly during the last 5 years, auxetic mechanical
metamaterials constructed from precisely architected polymer-based materials have …

The growing demands for enhanced impact resistance in modern engineering necessitate
the exploration of novel materials with superior properties. Among these materials, the …

Auxetic metamaterials have garnered the attention from researchers in the past decades
due to their advanced mechanical performance unparalleled by naturally occurring …

The implementation of periodic boundary conditions (PBCs) is one of the most important and
difficult steps in the computational analysis of structures and materials. This is especially true …

Poisson's ratio in auxetic materials shifts from typically positive to negative, causing lateral
expansion during axial tension. This scale‐independent characteristic, originating from …

A novel class of transversely-isotropic metamaterials with the potential to exhibit a wide
range of Poisson's ratios and stiffnesses is proposed in this work. These metamaterials …

Auxetic metamaterials are known for having a negative Poisson's ratio (NPR) and for
displaying the unexpected properties of lateral expansion when stretched and densification …
