In last two decades, it has been theoretically and experimentally demonstrated that seismic
metamaterials are capable of isolating seismic surface waves. Inertial amplification …

Hierarchical structures with constituents over multiple length scales are found in various
natural materials like bones, shells, spider silk and others, all of which display enhanced …

Most current shielding mechanisms against seismic disturbances fail in protecting structures
from low-frequency vibrations typically in the range of 1–10 Hz. This paper proposes a novel …

We propose topological metamaterials working in Hertz frequency range, constituted of
concrete pillars on the soil ground in a honeycomb lattice. Based on the analog of the …

The application of smart materials and metastructures has been rapidly increasing in
advanced multiphysical systems because of their ability to modify mechanical responses by …

This paper proposes a novel multidimensional composite periodic foundation for seismic
isolation. The composite periodic foundation achieves multidimensional attenuation by …

Surface wave is a major concern in ambient vibration mitigation. To this end, a novel shallow
buried periodic in-filled pipe barrier is proposed. Complex dispersion analysis is conduced …

Topological phononic crystals (PnCs) have attracted tremendous research attention in
recent years. A significant hallmark of these structures is that these crystals can support …

In engineering acoustics, the propagation of elastic flexural waves in plate and shell
structures is a common transmission path of vibrations and structure-borne noises. Phononic …

In this work, a concept of constructing inertant seismic metamaterials for Rayleigh wave
attenuation using inerter-based vibration absorbers (IDVAs) is proposed. The dynamic …
