Abstract We propose a class of auxetic three-dimensional lattice structures. The elastic microstructure can be designed to have an omnidirectional Poisson's ratio arbitrarily close to the stability limit of −1. The cubic behaviour of the periodic system has been fully characterized; the minimum and maximum Poisson's ratio and the associated principal directions are given as a function of the microstructural parameters. The initial microstructure is then modified into a body-centred cubic system… Expand

A 2D microstructure with auxetic out-of-plane behavior and non-auxetic in-plane behavior
Customarily, in-plane auxeticity and synclastic bending behavior (i.e. out-of-plane auxeticity) are not independent, being the latter a manifestation of the former. Basically, this is a feature ofExpand
Periodic Auxetics: Structure and Design
It is shown that a purely geometric approach to periodic auxetics is apt to identify essential characteristics of frameworks with auxetic deformations and can generate a systematic and endless series of periodic auxetic designs. Expand

Bulky auxeticity, tensile buckling and deck-of-cards kinematics emerging from structured continua
Complex mechanical behaviours are generally met in macroscopically homogeneous media as effects of inelastic responses or as results of unconventional material properties, which are postulated or dueExpand

A three‐dimensional rotating rigid units network exhibiting negative Poisson's ratios
Materials exhibiting auxetic behaviour get fatter when stretched (i.e. possess a negative Poisson's ratio). This property has been closely related to particular geometrical features of a system andExpand

Hierarchical Auxetic Mechanical Metamaterials
Using simulations on typical hierarchical multi-level rotating squares, it is shown that, through design, one can control the extent of auxeticity, degree of aperture and size of the different pores in the system, making the system more versatile than similar non-hierarchical ones. Expand
