Auxetic regions in large deformations of periodic frameworks [PDF]

open access: yes, 2018
In materials science, auxetic behavior refers to lateral widening upon stretching. We investigate the problem of finding domains of auxeticity in global deformation spaces of periodic frameworks.

Tunable Digital Material Properties of 3D Voxel Printers [PDF]

open access: yes, 2008
Digital materials are composed of many discrete voxels placed in a massively parallel layer deposition process, as opposed to continuous (analog) deposition techniques.

Auxetic Structures from Rotating Squares

open access: yes, 2022
The article deals with auxetic structures made on the basis of suitably connected rigid rotating squares (from Grima and Evans), with axes of rotation on the squares’ surface. The geometric model and the resulting relationships that allow for the determination of Poisson’s ratio are considered in detail.

Application of Auxetic Tubular Structure in Flow Control of the Throttle Valve

open access: yesEnergies, 2023
Compressed-air energy storage and other energy storage technologies play crucial roles in the use of renewable energy sources. As a key component in energy storage technology, the throttle valve plays an important role in throttling and reducing the ...

Computational modelling of structural integrity following mass loss in polymeric charred cellular solids [PDF]

open access: yes, 2014
A novel computational technique is presented for embedding mass-loss due to burning into the ANSYS finite element modelling code. The approaches employ a range of computational modelling methods in order to provide more complete theoretical treatment of ...

Constructing an overall dynamical model for a system with changing design parameter properties [PDF]

open access: yes, 2008
This study considers the identification problem for a class of non-linear parameter-varying systems associated with the following scenario: the system behaviour depends on some specifically prescribed parameter properties, which are adjustable.

A unified design method for 2D auxetic metamaterials based on a minimal auxetic structure

open access: yesInternational Journal of Solids and Structures, 2023
Auxetic metamaterials are architected structures that possess a unique property known as a negative Poisson's ratio. This remarkable characteristic enables them to expand or contract in a direction perpendicular to stretch or compression. Due to their exceptional attributes such as energy absorption and fracture resistance, these auxetic metamaterials ...

Review of Mechanics and Applications of Auxetic Structures

open access: yesAdvances in Materials Science and Engineering, 2014
One of the important mechanical properties of materials is Poisson’s ratio, which is positive for most of the materials. However, certain materials exhibit “auxetic” properties; that is, they have a negative Poisson’s ratio.

Explicit parametric solutions of lattice structures with proper generalized decomposition (PGD): applications to the design of 3D-printed architectured materials [PDF]

open access: yes, 2018
The final publication is available at Springer via http://dx.doi.org/10.1007/s00466-017-1534-9Architectured materials (or metamaterials) are constituted by a unit-cell with a complex structural design repeated periodically forming a bulk material with ...

A new auxetic structure with significantly reduced stress concentration effects

open access: yesMaterials & Design, 2019
Auxetic structures exhibit certain abnormal mechanical responses such as negative Poisson's ratios, mainly through the intertwined deformation attributes of inter-connected members of macro structural forms.
