Study of mechanical properties and enhancing auxetic mechanism of composite auxetic structures [PDF]

Engineering Reports, 2021
The auxetic structures attract much attention because of their good properties, such as enhanced energy absorption capacity and buckling resistance. It is an important topic to combine the auxetic structures with other materials or structures to improve ...

Performance of 3D printed topologically optimized novel auxetic structures under compressive loading: experimental and FE analyses

Journal of Materials Research and Technology, 2021
The auxetic structures, because of their negative Poisson's ratio, have a lot of potential applications in the aerospace and automobile industry due to their exceptional mechanical properties under bending, shear, and compression loads.

Design and evaluation of 3D-printed auxetic structures coated by CWPU/graphene as strain sensor [PDF]

Scientific Reports, 2022
A strain sensor characterized by elasticity has recently been studied in various ways to be applied to monitoring humans or robots. Here, 4 types of 3D-printed auxetic lattice structures using thermoplastic polyurethane as raw material were characterized:

Cellular Auxetic Structures for Mechanical Metamaterials: A Review. [PDF]

Sensors (Basel), 2020
Recent advances in lithography technology and the spread of 3D printers allow us a facile fabrication of special materials with complicated microstructures. The materials are called “designed materials” or “architectured materials” and provide new opportunities for material development.

Investigation of the Auxetic of a novel geometric structure and improvement of Poisson’s ratio at different inner thicknesses

Gazi Üniversitesi Fen Bilimleri Dergisi, 2023
Poisson’s ratio, one of the important mechanical properties of materials and structures, is positive for almost all of the known materials and structures. However, auxetic materials or structures has negative Poisson’s ratios.

Bistable auxetic surface structures

ACM Transactions on Graphics, 2021
We present Bistable Auxetic Surface Structures , a novel deployable material system based on optimized bistable auxetic cells. Such a structure can be flat-fabricated from elastic sheet material, then deployed towards a desired double-curved target shape by activating the bistable mechanism of its component cells. A
