In the past decades, many mechanical metamaterials with uncommon static properties have
been reported. On the other hand, mechanical metamaterials possessing extraordinary …

The classical continuum mechanics assumes that a material is a composition of an infinite
number of particles each of which is a point that can only move and interact with its nearest …

The intensity of a wave emitted by a transducer affects its performance critically, especially
when the emitted wave is omnidirectional. However, the development of omnidirectional …

In this investigation, the nonreciprocal transmission of elastic waves is achieved by the
combination of asymmetric structure and nonlinear material. Our attention is focused on the …

A new elastic metamaterial model is proposed based on translational resonance to obtain
simultaneously negative mass and negative modulus within specific frequency ranges …

Labyrinthine acoustic metamaterial provides a flexible and unprecedented ability to
manipulate the sound wave propagation, such as sound blocking, cloaking, supertunneling …

We study three different 1D continuous models (extensional rods, Euler and Timoshenko
beams) for addressing the dynamic properties of those microstructural materials containing …

In the design of locally resonant acoustic metamaterials (LRAMs), the incompressible rubber
is widely used. However, the physical behavior of LRAMs with a ternary structure is very …

The behaviour of elastic metamaterials is dominated by the local structure of their
representative cells and their periodicity. Previous works indicated that introducing multiple …

A new two-dimensional periodic elastic metamaterial system is proposed, which exhibits
multiple local resonances and can generate negative effective parameters. In certain …
