Compression Behavior of EBM Printed Auxetic Chiral Structures [PDF]

open access: yesMaterials, 2022
In this study, the cyclic compression and crush behavior of chiral auxetic lattice structures produced from titanium alloy (Ti6Al4V) metallic powder using electron beam melting (EBM) additive manufacturing technology is investigated numerically and experimentally.

Machine learning accelerated design of auxetic structures

open access: yesMaterials & Design, 2023
Auxetic metamaterials exhibit unusual expansion perpendicular to the direction of tensile loading, a behavior known as negative Poisson's ratio (NPR). The microstructures of auxetic metamaterials require rational design.

A novel auxetic structure based bone screw design: Tensile mechanical characterization and pullout fixation strength evaluation

open access: yesMaterials & Design, 2020
It was supposed that auxetic structure with negative Poisson's ratio (NPR) expands under stretch and could enhance the screw-bone fixation. In this study, the novel auxetic structure based bone screws were designed, and mechanical properties and fixation

Capability of auxetic femoral stems to reduce stress shielding after total hip arthroplasty

open access: yesJournal of Orthopaedic Translation, 2023
Background: Stress shielding ​(SS) is considered the main mechanical cause of femoral stem loosening after total hip arthroplasty (THA). This study introduces an auxetic lattice femoral stem structure with negative Poisson's ratio that can expand ...

DNA Nanostar Structures with Tunable Auxetic Properties

open access: yesMolecular Systems Design & Engineering, 2023
ABSTRACTAuxetic structures are unique with a negative Poisson’s ratio. Unlike regular materials, they response to external loading with simultaneous expansion or compression in all directions, rendering powerful properties advantageous in diverse applications from manufacturing to space engineering.

An Experimental Study of Auxetic Tubular Structures

open access: yesMaterials, 2022
Auxetic tubular structures are widely known structures, characterized by a negative Poisson’s ratio upon stretching and deformation in the axial and transverse directions, which have numerous application possibilities. In this paper, tubular structures were realized by rolling up planar auxetic structures and using rigid square frames as unit cells ...

Engineering Auxetic Cylinders and Intestine to Improve Longitudinal Intestinal Lengthening and Tailoring Procedure

open access: yesBioengineering, 2022
Auxetic materials can be exploited for coupling different types of tissues. Herein, we designed a material where the microorganism metabolic activity yields the formation of buckled/collapsed bubbles within gelling silicone cylinders thus providing ...

Theory of strains in auxetic materials [PDF]

open access: yes, 2012
Auxetic materials, or negative-Poisson's-ratio materials, are important technologically and fascinating theoretically. When loaded by external stresses, their internal strains are governed by correlated motion of internal structural degrees of freedom ...

INVESTIGATION OF THE AUXETIC BEHAVIOR OF AN ORIGINAL LATTICE STRUCTURE DESIGN

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2023
Auxetic structures are special structures with negative Poisson's ratio due to their geometric shapes in their internal structure. When tensile force is applied to these structures, transverse and longitudinal expansions are observed, while transverse ...
