Estimation of wave propagation velocity on a channel with smooth and rough bed

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Natural hazards such as tsunamis, impulse waves and dam-break waves are rare, but extremely destructive. In recent times, more importance was given to structures that could withstand such events, however, uncertainties still exist in the estimation of wave ...

Growth and nonlinear response of driven water bells

John Martin Kolinski

A water bell forms when a fluid jet impacts upon a target and separates into a two-dimensional sheet. Depending on the angle of separation from the target, the sheet can curve into a variety of different geometries. We show analytically that harmonic pertu ...

Seismic response of rock joints under obliquely incident wave

Yang Zou

Seismic response of joints which are found to be ubiquitous in rock masses is of great interest to rock engineers, geophysicists and seismologists. In the past years, wave propagation across rock joints has been the subject of extensive theoretical and exp ...

Analytical analysis of slow and fast pressure waves in a two-dimensional cellular solid with fluid-filled cells

Vladimir Dorodnitsyn, Bart Van Damme

Wave propagation in cellular and porous media is widely studied due to its abundance in nature and industrial applications. Biot's theory for open-cell media predicts the existence of two simultaneous pressure waves, distinguished by its velocity. A fast w ...

A Further Study on Wave Propagation Across a Single Joint with Different Roughness

Xin Chen, Jian Zhao, Yang Zou

As a key dynamic feature of the rock mass, joint results in wave attenuation when a stress wave propagates across it. An experimental study has obtained the relation between the transmission coefficient and the contact area ratio of joints with different t ...

The Velocity of the Propagating Wave for General Coupled Scalar Systems

Nicolas Macris, Rafah El-Khatib

We consider spatially coupled systems governed by a set of scalar density evolution equations. Such equations track the behavior of message-passing algorithms used, for example, in coding, sparse sensing, or constraint-satisfaction problems. Assuming that ...

Wave propagation in periodic buckled beams. Part II: Experiments

Alessandro Spadoni, Florian Paul Robert Maurin

Buckled periodic beams possess a geometrically nonlinear, load-deformation relation and intrinsic length scales such that stable, nonlinear waves are possible. In part I of this paper, a model has been derived that predict compressive/rarefaction, superson ...

Acoustic monitoring of laboratory hydraulic fracture growth under stress and pore pressure

Brice Tanguy Alphonse Lecampion, Thomas Emmanuel Blum

Fluid-driven fracturing is used in a wide range of applications, including oil and gas extraction, geothermal energy recovery, and CO2 sequestration. In order to efficiently fracture the targeted rock formation, theoretical models provide estimates of the ...
