Integrated Design and Process Optimization of FDM‐Fabricated Hexagonal Architected Thin‐Walled PA12 Tubes for Improved Compressive and Energy Absorption Performance

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
FDM‐fabricated PA12 thin‐walled tubes with five hexagonal architected designs (D1–D5) of increasing nodal connectivity were investigated to determine the effects of wall architecture, layer height, and print angle orientation on compressive performance, energy absorption, and dimensional accuracy.

Auxetic structures in civil engineering applications: Experimental (by 3D printing) and numerical investigation of mechanical behavior

Results in Materials
Auxetic materials are a group of metamaterials that have a negative Poisson's ratio. The most important advantage of auxetics over conventional materials is higher energy absorption. Consequently, in Civil Engineering, a wide range of applications may be

Exploration of auxetics materials in sport

, 2021
A special property of auxetic materials is their negative Poisson’s ratio : this material shortens or lengthen in all directions when subjected respectively to a compressive or tensile force. This unusual characteristic opens up new perspectives in many fields. Sport is one of the fields where these properties can be well exploited. Already studied and

The Viscoelastic Behaviour of Auxetic Metamaterials

physica status solidi (b), Volume 263, Issue 8, August 2026.
Stretch‐only auxetic unit‐cell viscoelastic models are extended from elastic honeycomb and keyway lattices using Maxwell and standard‐linear‐solid representations. Different horizontal and oblique relaxation responses make Poisson's ratio time‐ and frequency‐dependent, enabling tuneable auxetic behaviour for damping and adaptive structures.

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Random auxetics from buckling fibre networks

Nature Communications, 2019
Auxetic materials have usually been developed with periodically arrange structures. Here, the authors electrospin fibre networks, and show both theoretically and experimentally that these random structures have pronounced auxetic behaviour with negative ...

Auxetic metamaterials: A route to auxeticity in textile fibrous structures - potential application on protective apparel

Journal of Industrial Textiles
Auxetic fibrous structures represent an innovative class of metamaterials that exhibit a negative Poisson’s ratio, meaning they expand laterally when stretched and contract when compressed.
