Mechanical metamaterials enable the creation of structural materials with unprecedented
mechanical properties. However, thus far, research on mechanical metamaterials has …

Mechanical metamaterials are man-made structures with counterintuitive mechanical
properties that originate in the geometry of their unit cell instead of the properties of each …

Mechanical metamaterials have opened an exciting venue for control and manipulation of
architected structures in recent years. Research in the area of mechanical metamaterials …

Nanoscale spacecrafts have shed light on an audacious but promising vision for interstellar
travel to neighboring planets beyond the solar system. The nanocrafts can be accelerated to …

Guided waves, elastic waves propagating through bounded structures, play a pivotal role in
various applications, including ultrasonic non-destructive testing and structural health …

In this study, we present a novel topology-optimized design of a two-dimensional cavity-free
mechanical metamaterial with a negative coefficient of thermal expansion. We challenge the …

Mechanical metamaterials attract a lot of interest because of the peculiar mechanical
properties. Especially in adjustment of Poisson's ratio of structures, the auxetic mechanical …

We report a topology-transformable resonator with two distinct stable states, one
kinematically determinate and endowed with nearly rigid-body motion at low-frequencies …

The idea of manipulating transverse waves by longitudinal vibrations has been proposed in
this article. The band structures of distributed resonators on an Euler beam undergoing high …

We demonstrate experimentally the manipulation of Lamb waves guided along
reconfigurable phononic circuits created by defects composed of threaded rods held with …
