Abstract 4D printing refers to single-material or multi-material printing of a device or object
that can be transformed from a 1D strand into pre-programed 3D shape, from a 2D surface …

A novel hierarchical re-entrant honeycomb metamaterial is proposed by integrating the re-
entrant honeycomb (RH) with square unit cell and named as square re-entrant honeycomb …

The aim of this paper is to introduce dual-material auxetic meta-sandwiches by four-
dimensional (4D) printing technology for reversible energy absorption applications. The …

Elastic metamaterials with local resonance bandgaps are promising for low-frequency
vibration mitigation. However, such locally resonant metamaterials inherently possess …

There is inevitably a conflict between multiple objectives when designing elastic metaplates
(EMPs) with desirable functionalities from the perspective of practical applications. The non …

In order to enhance the vibration reduction capacity in a wide frequency range, a novel
acoustic metamaterial beam with periodically variable cross-sections is designed by …

In this study, the vibration isolation characteristics and crushing behaviors of novel
hierarchical mechanical metamaterials are investigated. Numerical analyses are carried out …

Steering flexural waves in thin plates benefits several applications, including vibration
energy harvesting and micro-electro-mechanical systems (MEMS). This study proposes a …

This study proposes the use of a linear and geometrically nonlinear inerter-based resonator
in locally resonant acoustic metamaterials (LRAMs) and evaluates the performance on low …

In order to acquire multiple and wider stop bands in periodic sandwich lattice, this work
applies the inertial amplification mechanisms to the composite sandwich beam with …
