Acoustic ‘black holes’ for flexural waves as effective vibration dampers
Abstract Elastic plates of variable thickness gradually decreasing to zero (elastic wedges) can support a variety of unusual effects for flexural waves propagating towards sharp edges of suchExpand
Generation of Ground Vibrations by Superfast Trains
Ground vibrations generated by superfast trains are studied theoretically, taking into account the contribution of each sleeper of the track subjected to the action of the carriage wheel axles. It isExpand
New type of vibration dampers utilising the effect of acoustic 'black holes'
One of the well-known ways of damping resonant flexural vibrations of different engineering structures or their elements, e.g. finite plates or bars, is to reduce reflections of flexural waves fromExpand
Noise and Vibration from High-Speed Trains
Presents the views of leading international experts on the current status of the problems of generation and propagation of noise and vibration from high-speed trains, and suggests possible ways ofExpand
On the theory of railway-induced ground vibrations
In the present paper, the theory of generation of ground vibrations by moving train is considered. The theory takes into account contribution of each sleeper of the track subjected to the action ofExpand
Surface acoustic waves in inhomogeneous media
This monograph covers important problems caused by the interaction of different types of surface acoustic waves with surface inhomogeneities. The problem of surface acoustic wave interaction withExpand
Contamination of indoor air by toxic soil vapours: a screening risk assessment model
Abstract A simple steady-state model is derived for estimating the concentration of vapour-phase contaminants in indoor air, given the contaminant concentration in the soil. The model includes theExpand
Effect of surface phenomena in solids on surface acoustic waves
Abstract A review of the modern status of the theory of surface acoustic waves in solids with accounting the surface effects is presented. The main approaches are discussed to the determination ofExpand
Damping of structural vibrations in beams and elliptical plates using the acoustic black hole effect
Flexural waves in beams and plates slow down if their thickness decreases. Such property was used in the past for establishing the theory of acoustic black holes (ABH). The aim of the present paperExpand
