Cavitation Induction by Projectile Impacting on a Water Jet [PDF]
, 2019 The present paper focuses on the simulation of the high-velocity impact of a projectile impacting on a water-jet, causing the onset, development and collapse of cavitation. The simulation of the fluid motion is carried out using an explicit, compressible,

Sliding without slipping under Coulomb friction: opening waves and inversion of frictional force
, 2016 An elastic layer slides on a rigid flat governed by Coulomb's friction law. We demonstrate that if the coefficient of friction is high enough, the sliding localizes within stick-slip pulses, which transform into opening waves propagating at intersonic ...

Statics and dynamics of fluids in nanotubes [PDF]
, 2012 The purpose of this article is to study the statics and dynamics of nanotubes by using the methods of continuum mechanics. The nanotube can be filled with only a liquid or a vapour phase according to the physicochemical characteristics of the wall and to

Edge waves and localisation in lattices containing tilted resonators
, 2017 The paper presents the study of waves in a structured geometrically chiral solid. A special attention is given to the analysis of the Bloch-Floquet waves in a doubly periodic high-contrast lattice containing tilted resonators.

Lattice Boltzmann model approximated with finite difference expressions
, 2017 We show that the asymptotic properties of the link-wise artificial compressibility method are not compatible with a correct approximation of fluid properties.

Compaction and dilation rate dependence of stresses in gas-fluidized beds
, 2006 A particle dynamics-based hybrid model, consisting of monodisperse spherical solid particles and volume-averaged gas hydrodynamics, is used to study traveling planar waves (one-dimensional traveling waves) of voids formed in gas-fluidized beds of narrow ...

Observation of non-local dielectric relaxation in glycerol
, 2011 Since its introduction, liquid viscosity and relaxation time $\tau$ have been considered to be an intrinsic property of the system that is essentially local in nature and therefore independent of system size.

Scalable variable-index elasto-optic metamaterials for macroscopic optical components and devices
Nature Communications, 2017 Optical metamaterials with an artificial subwavelength structure offer new approaches to implement advanced optical devices. However, some of the biggest challenges associated with the development of metamaterials in the visible spectrum are the high ...

, 2017 We consider wave propagation along fluid-loaded structures which take the form of an elastic plate augmented by an array of resonators forming a metasurface, that is, a surface structured with sub-wavelength resonators.

Surface Phonons and Other Localized Excitations
, 1999 The diatomic linear chain of masses coupled by harmonic springs is a textboook model for vibrational normal modes (phonons) in crystals. In addition to propagating acoustic and optic branches, this model is known to support a ``gap mode'' localized at ...
