Pyramid-core lattice sandwich structures (PCLSSs) have been widely used in various
engineering fields due to their high stiffness-to-density ratio. Although the advantages of …

We design, simulate, and experimentally characterize a reconfigurable elastic metamaterial
with beyond-nearest-neighbor (BNN) coupling. The structure is composed from the popular …

This work presents a strategy to design three-dimensional elastic periodic structures
endowed with complete bandgaps, the first of which is ultra-wide, where the top limits of the …

Locally resonant piezoelectric metamaterials offer outstanding vibration attenuation
properties with the versatility in updating local resonances using either analog or digital …

ABSTRACT A subwavelength seismic metamaterial (SM) consisting of a three-component
SM plate (SMP) and a half space is proposed to attenuate ultra-low frequency seismic …

A reinforcement learning approach to design optimised graded metamaterials for
mechanical energy confinement and amplification is described. Through the proximal policy …

In this paper, we incorporate the effect of nonlinear damping with the concept of locally
resonant metamaterials to enable vibration attenuation beyond the conventional bandgap …

Precise manipulation of the direction and redirection of vibrational wave energy is a key
demand in wave physics and engineering. We consider the paradigm of a finite framelike …

We investigate the propagation of Rayleigh waves in a half-space coupled to a nonlinear
metasurface. The metasurface consists of an array of nonlinear oscillators attached to the …

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 …
