In this work we first propose a wave and Rayleigh–Ritz method (WRRM) to analyze the
vibrations of periodic systems. It is well-known that one of the main difficulties of the …

The Colloquium reviews recent progress in the effective description of strongly correlated
phases of matter with spontaneously broken translations, such as charge density waves or …

Rubber components such as engine or suspension bearings are loaded during operation
with large deformations and high-frequency loads. In industrial applications, finite element …

Mechanical stresses across different length scales play a fundamental role in understanding
biological systems' functions and engineering soft machines and devices. However, it is …

The fluid-saturated porous layered (FSPL) media widely exist in the Earth's subsurface and
their overall mechanical properties, microscopic pore structure and wave propagation …

We study the propagation of guided elastic waves in a highly-stretched Ecoflex© plate, a
nearly-incompressible elastomer. The plate is subjected to a nearly-uniaxial stress with an …

Sedimentary strata typically exhibit the characteristics of transverse isotropy (VTI) with a
vertical axis of symmetry. However, fractures in sedimentary strata tend to produce …

To produce sounds, we adjust the tension of our vocal folds to shape their properties and
control the pitch. This efficient mechanism offers inspiration for designing reconfigurable …

The time-dependent behaviour of polymeric composites is critical in a broad range of
applications, including those in marine, aerospace, and automotive environments. In the …

In this study, a new type of 2D piezoelectric phononic crystal with a square hollow and
convex structures is designed and established. A theoretical study of the piezoelectric …
