The study of phononic materials and structures is an emerging discipline that lies at the
crossroads of vibration and acoustics engineering and condensed matter physics. Broadly …

Vibration and sound control is critical to many practical engineering systems in order to
minimise the detrimental effects caused by unavoidable vibrations and noises …

We report a new type of phononic crystals with topologically nontrivial band gaps for both
longitudinal and transverse polarizations, resulting in protected one-way elastic edge …

Material properties can be tailored through modification of their geometry or architecture.
With this concept, a lot of smart materials, metamaterials, and smart structures have been …

Auxetic materials become thicker rather than thinner when stretched, exhibiting an unusual
negative Poisson's ratio well suited for designing shape transforming metamaterials. Current …

We investigate the unique mechanical properties of reentrant 3D origami structures based
on the Tachi-Miura polyhedron (TMP). We explore the potential usage as mechanical …

The fundamental topology of cellular structures—the location, number and connectivity of
nodes and compartments—can profoundly affect their acoustic,,–, electrical, chemical …

Mechanical properties of materials have long been one of the most fundamental and studied
areas of materials science for a myriad of applications. Recently, mechanical metamaterials …

Plane wave propagation in infinite two-dimensional periodic lattices is investigated using
Floquet-Bloch principles. Frequency bandgaps and spatial filtering phenomena are …

This paper is concerned with flexural wave propagation and vibration transmission in beams
with periodically attached vibration absorbers. Such periodic systems feature unique wave …
