Bistable auxetic surface structures
ACM Transactions on Graphics, 2021We 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

Optimization of auxetic structures for MEMS applications
2016 17th International Conference on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microelectronics and Microsystems (EuroSimE), 2016Complex inertial Micro Electro Mechanical Systems (MEMS) usually require the simultaneous motion of the masses in more than one direction and an overall linear behavior. Furthermore, since it is usually very difficult to actuate the device in all the required directions, complex spring configurations for the conversion of the motion are needed. Here we

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2023
Additive manufacturing is the most widely used approach to fabricating cellular structures. Research interests in auxetics are increasing due to their unique properties like impact energy absorption. In this work, a novel approach to enhance the mechanical properties of auxetics is proposed.

Mixed auxeticity of auxetic sandwich structures
physica status solidi (b), 2012AbstractPreviously, a sandwich structure in which the Poisson ratios of the core and facesheets possess opposite signs has been shown to exhibit overall conventional and auxetic behavior depending on the loading mode – axial loading or bending – for an intermediate range of relative core thickness.

Auxetic Cellular Materials and Structures
Aerospace, 2005Auxetic materials and structures exhibit the very unusual property of becoming wider when stretched and narrower when squashed (i.e. they have a negative ‘Poisson’s ratio’). This property results in many beneficial effects in the characteristics of the system that make auxetics superior to conventional systems in many practical and high tech ...

Auxetic metamaterials and structures: a review
Smart Materials and Structures, 2018Materials and structures with negative Poisson's ratio exhibit a counter-intuitive behaviour. Under uniaxial compression (tension), these materials and structures contract (expand) transversely. The materials and structures that possess this feature are also termed as 'auxetics'.

Development of spiral auxetic structures
Composite Structures, 2018Abstract An auxetic tow or fiber bundle that will expand in diameter when extended axially would be very useful. It could be woven into a shape-changing cloth, perhaps used for ballistic protection , or as an easily cleaned filter. To explore this concept, spiral fiber bundle structures under tension were explored. Theory describing the geometry of
