Phase-field method is a density-based computational method at the mesoscale for modeling
and predicting the temporal microstructure and property evolution during materials …

Mechanical metamaterials and phononic crystals enable localizing, focusing, and guiding of
elastic or acoustic waves in various ways. Here, we describe the physical mechanisms …

Inspired by sonic engineering, locally resonant metamaterials have attracted much attention
from researchers in civil engineering for their unique characteristics of stress wave …

In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

Rationally designed artificial materials enable mechanical properties that are inaccessible
with ordinary materials. Pushing on an ordinary linearly elastic bar can cause it to be …

Mechanical metamaterials exhibit some superior mechanical properties such as ultrahigh
strength-to-weight ratio, negative bulk-modulus, negative stiffness, negative mass-density …

Within a time span of 15 years, acoustic metamaterials have emerged from academic
curiosity to become an active field driven by scientific discoveries and diverse application …

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

This paper develops a novel type of two-dimensional (2D) locally resonant (LR)
metamaterials with quasi-zero-stiffness (QZS) property both in the horizontal and vertical …

In the past two decades, the research on acoustic metamaterials has flourished, which is
also benefited from the development of additive manufacturing technology. The exotic …
