Modelling of masonry walls rendered with auxetic foam layers against vehicular impacts

, 2016
Masonry walls allow easy intrusion of the impacting vehicles into the impacted buildings. The cause of the damage due to vehicular impacts in masonry walls is the generation of tensile stresses due to “Poisson’s effect”.

Harnessing cracks in metal films: Design strategies for stretchable conductors

InfoMat, Volume 8, Issue 9, September 2026.
In stretchable electronics, metal film‐based components function either as strain‐insensitive interconnects/electrodes or as strain‐sensitive sensors, both of which are governed by crack‐induced electromechanical responses, yet these two roles have often been discussed separately in previous reviews.

Auxetic Dihedral Escher Tessellations

Graphical Models
The auxetic structure demonstrates an unconventional deployable mechanism, expanding in transverse directions while being stretched longitudinally (exhibiting a negative Poisson’s ratio). This characteristic offers advantages in diverse fields such as structural engineering, flexible electronics, and medicine.

Motion‐Driven Self‐Visualizing Soft Robots Enabled by Mechanoluminescent Tubular Fibers

Small Structures, Volume 7, Issue 9, September 2026.
ML tubular fibers consisting of a ZnS:Cu–PDMS core confined within a silicone tube are integrated onto pneumatically driven soft robots. Mechanical deformation directly generates visible light without external electrical power, allowing robot motion and local deformation to be visualized in real time.

New auxetic materials

, 2000
Materials with negative Poisson's ratios (auxetic) exhibit the very unusual property of becoming wider when stretched and narrower when squashed. This thesis presents a global classification system for auxetics based on the geometry and deformation ...

Investigating the Thermomechanical Stability and Vibration of Curved Smart Sandwich Nanoplates Integrated With a Hexachiral Auxetic Core and Magneto‐Electro‐Elastic Surface Layers

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 9, September 2026.
ABSTRACT This study investigates the thermal vibration and buckling characteristics of smart sandwich nanoplates featuring a hexachiral auxetic core and piezoelectric/piezomagnetic face sheets. Utilizing the nonlocal strain gradient theory (NSGT) and a higher‐order shear deformation framework, the governing equations are derived to capture size ...
