Monitoring Auxetic Structure with FBG Sensor

e-Journal of Nondestructive Testing
Auxetic materials are a particular class of materials which present a negative Poisson ratio (NPR). This means that once they are stretched, they expand in the directions orthogonal to the applied load. The dual behaviour occurs during compression tests.

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.

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.

Mechanism-driven recoil performance in auxetic structures: Numerical modeling and additive manufacturing verification

Journal of Materials Research and Technology
This study presents a novel auxetic mechanical structure (AMS) designed to reduce recoil in stents application. Building upon a peanut-shaped auxetic lattice with a negative Poisson's ratio, various single- and double-layer AMS configurations were ...

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 ...
