Abstract Machine learning (ML), as a component of artificial intelligence, encourages
structural design exploration which leads to new technological advancements. By …

We propose a new nonlinear elastic metamaterial which shows tunable bandgap at quasi-
static frequency, starting from zero frequency. While there have been active researches on …

This work proposes a graded metamaterial-based energy harvester integrating the
piezoelectric energy harvesting function targeting low-frequency ambient vibrations (< 100 …

Unlike well-studied locally resonant (LR) metamaterials with a periodic array of identical
resonators,'graded'LR metamaterials consist of an array of resonators with a spatially …

We numerically and experimentally investigate spatially programmable rainbow trapping
and band-gap enhancement using a graded piezoelectric metamaterial beam with unit cells …

Metamaterials (MMs), which include phononic crystals (PCs) as a particular type, exhibit
anomalous wave propagation properties through artificial design of topologies or lattice …

This paper explores a new approach to reducing the interior noise of one vehicle body
through the flexural wave bandgap. The phononic crystal is designed by attaching the …

It has been well explored in the literature that intentionally introduced (designed)
nonlinearities offer significant advantages in vibration absorption and isolation problems. In …
