Normal modes and acoustic properties of an elastic solid with line defects [PDF]
, 2014 The normal modes of a continuum solid endowed with a random distribution of line defects that behave like elastic strings are described. These strings interact with elastic waves in the bulk, generating wave dispersion and attenuation.

Macroscopic Quantum Test with Bulk Acoustic Wave Resonators. [PDF]
Physical Review Letters, 2022 Recently, solid-state mechanical resonators have become a platform for demonstrating nonclassical behavior of systems involving a truly macroscopic number of particles. Here, we perform the most macroscopic quantum test in a mechanical resonator to date,

Weierstrass's criterion and compact solitary waves [PDF]
, 2007 Weierstrass's theory is a standard qualitative tool for single degree of freedom equations, used in classical mechanics and in many textbooks. In this Brief Report we show how a simple generalization of this tool makes it possible to identify some ...

On angled bounce-off impact of a drop impinging on a flowing soap film [PDF]
, 2017 Small drops impinging angularly on thin flowing soap films frequently demonstrate the rare emergence of bulk elastic effects working in-tandem with the more common-place hydrodynamic interactions. Three collision regimes are observable: (a) drop piercing

Flow estimation in a steel pipe using guided waves [PDF]
, 2016 In this investigation, a flow rate estimation guided wave based scheme in pipes is proposed. The effect of the fluid over the propagation of longitudinal waves has been experimentally studied by using several laminar flows of water transported by a ...

Anomalous Topological Edge States in Non-Hermitian Piezophononic Media. [PDF]
Physical Review Letters, 2020 The bulk-boundary or bulk-edge correspondence is a principle relating surface confined states to the topological classification of the bulk. By marrying non-Hermitian ingredients in terms of gain or loss with media that violate reciprocity, an ...

The application of ultrasonic NDT techniques in tribology [PDF]
, 2005 The use of ultrasonic reflection is emerging as a technique for studying tribological contacts. Ultrasonic waves can be transmitted non-destructively through machine components and their behaviour at an interface describes the characteristics of that ...

Non-Hermitian elastodynamics in gyro-odd continuum media
Communications Materials, 2022 Linear elasticity has long been considered a well-established research area using conservative field theory. However, the discovery of odd-elasticity challenges the essential energy conservation assumption, which together with gyroscopic ingredients ...

Libration driven multipolar instabilities [PDF]
, 2014 We consider rotating flows in non-axisymmetric enclosures that are driven by libration, i.e. by a small periodic modulation of the rotation rate. Thanks to its simplicity, this model is relevant to various contexts, from industrial containers (with small

Elastic interface acoustic waves in twinned crystals [PDF]
, 2012 A new type of Interface Acoustic Waves (IAW) is presented, for single-crystal orthotropic twins bonded symmetrically along a plane containing only one common crystallographic axis.
