Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a
material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is …

Metamaterials are rationally designed composites aiming at effective material parameters
that go beyond those of the ingredient materials. For example, negative metamaterial …

Rationally designed artificial materials, called metamaterials, allow for tailoring effective
material properties beyond (“meta”) the properties of their bulk ingredient materials. This …

Mechanical metamaterials, also known as architected materials, are rationally designed
composites, aiming at elastic behaviors and effective mechanical properties beyond ('meta') …

Crystallography typically studies collections of point particles whose interaction forces are
the gradient of a potential. Lifting this assumption generically gives rise in the continuum …

In this paper, we propose an innovative design of an elastic network, which is capable of
channelling the energy supplied by an external source towards any of its endpoints, that can …

Abstract A lattice (or 'grillage') of elastic Rayleigh rods (possessing a distributed mass
density, together with rotational inertia) organized in a parallelepiped geometry can be …

Rayleigh waves are analysed in elastic lattices incorporating inertial devices that couple in-
plane displacements. The vector problems of elasticity for a triangular lattice and its long …

We demonstrate a new method of achieving topologically protected states in an elastic
hexagonal system of trusses by attaching gyroscopic spinners, which bring chirality to the …

The transient analysis of gyro-elastic structured media, composed of periodically placed
masses interconnected by elastic rods and attached to gyroscopic spinners, is presented …
