Constitutive memory equations for auxetic materials

Mathematical Modelling and Analysis
In this note we suggest a set of constitutive equations for anelastic materials whose internal structure can present anomalous variations resulting from external effects of tension/compression, as in auxetic media. For these problems we require of a new function related with the variation of internal structure, which allows us to define a threshold ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

CrossMatAgent: AI‐Assisted Design of Manufacturable Metamaterial Patterns via Multi‐Agent Generative Framework

Advanced Intelligent Discovery, Volume 2, Issue 4, August 2026.
CrossMatAgent is a multi‐agent framework that combines large language models and diffusion‐based generative AI to automate metamaterial design. By coordinating task‐specific agents—such as describer, architect, and builder—it transforms user‐provided image prompts into high‐fidelity, printable lattice patterns.

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.

Auxetic Materials

This report examines auxetic materials which are designed to have a negative Poisson’s ratio. Thismeans they expand sideways when stretched. This unusual behaviour provides unique mechanicaladvantages, such as better resistance to indentation, improved toughness against fractures, andbeneficial synclastic curvature, which aids in uniform bending.
