Effect of Compressive Strain Rate on Auxetic Foam
Applied Sciences, 2021 Auxetic foams have previously been shown to have benefits including higher indentation resistance than their conventional counterparts, due to their negative Poisson’s ratio, making them better at resisting penetration by concentrated loads.

Strategic Design of Soft Actuators in Translational Medical Robotics for Human‐Centered Healthcare
Advanced Robotics Research, EarlyView.Soft robotics enables biocompatible, compliant medical devices, but clinical translation requires design‐driven engineering beyond materials. This perspective reviews implantable, surgical, and wearable systems by actuation mechanism, highlighting how optimized architectures and integration improve mechanical interfacing, adaptability, and durability ...

Modelling of auxetic foam embedded brittle materials and structures
, 2016 Building structures use brittle materials extensively. Under impact or blast loads these structures perform poorly due to tensile strains caused by Poisson’s effect normal to the direction of such loadings.

Bistable Networks Enable Complex Shape Changes
Advanced Science, EarlyView.Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Elasto-plastic shear behavior of reinforced honeycomb and auxetic reentrant lattices
Millenium, 2018 Introduction: Auxetic materials possess a negative Poisson’s ratio. Even though, the existence of isotropic auxetics is theoretically possible, they seem to be absent in natural states thus, there has been an effort to produce artificial auxetics mostly ...

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning
Advanced Intelligent Discovery, EarlyView.This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

The structure design and application of metamaterials with negative Poisson's ratio
EPJ Applied MetamaterialsMetamaterials with negative Poisson's ratio, also called auxetic metamaterials, are artificially engineered structures or materials that possess extraordinary auxetic effect, high shear modulus, excellent impact resistance, and remarkable energy ...
