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

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.

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.

Auxetic metamaterials and structures: a review
Smart Materials and Structures, 2018Abstract Materials 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’.

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 ...

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

Damping in auxetic materials and structures.
The Journal of the Acoustical Society of America, 2010Negative Poisson’s ratio (NPR) (otherwise called auxetics) materials and structures feature enhanced energy absorption under cyclic loading both at low- and high-frequency excitations. We show in this paper experimental and simulation results related to open cell PU-PE foams, honeycombs, and composites, all exhibiting a negative Poisson’s ratio value ...

Auxetic Structures Analysis: Exploratory Study on Auxetic Materials in Additive Manufacturing
Ibero-Latin American Congress on Computational Methods in Engineering (CILAMCE)Auxetic structures have aroused significant interest in the scientific community due to their unique properties of lateral expansion when subjected to tensile forces, and transverse deformation when subjected to negative Poisson's ratio. This article offers an analysis of these structures, where the theoretical foundations of the negative Poisson's ...
