Development of a textile structure for multi-directional auxetic deformation
Materials & Design, 2022 Previous studies of auxetic composites reinforced with woven fiber structures focused on unidirectional tension or compression. Multiple fibers are often required to play different roles in the structure, making it difficult to fully exploit the ...

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

Periodic Auxetics: Structure and Design [PDF]
The Quarterly Journal of Mechanics and Applied Mathematics, 2017 Materials science has adopted the term of auxetic behavior for structural deformations where stretching in some direction entails lateral widening, rather than lateral shrinking. Most studies, in the last three decades, have explored repetitive or cellular structures and used the notion of negative Poisson's ratio as the hallmark of auxetic behavior ...
