Characterization and synthesis of Rayleigh damped elastodynamic networks
Networks & Heterogeneous Media, 2014 We consider damped elastodynamic networks where the damping matrix is assumed to be a non-negative linear combination of the stiffness and mass matrices (also known as Rayleigh or proportional damping). We give here a characterization of the frequency response of such networks.

Computation of Rayleigh Damping Coefficients for the Seismic Analysis of a Hydro-Powerhouse
Shock and Vibration, 2017 The mass and stiffness of the upper and lower structures of a powerhouse are different. As such, the first two vibration modes mostly indicate the dynamic characteristics of the upper structure, and the precise seismic response of a powerhouse is ...

Influence of the upper gravity-wave damping layer on precipitation over complex terrain
Frontiers in Environmental Science, 2022 The upper boundary condition of a numerical model can significantly influence the model prediction results. This study used the Weather Research and Forecasting model to introduce the Rayleigh damping layer in the complex terrain of southern Gansu, China.

Numerical Simulation of the Infinite Medium of Dry Soil in Dynamic Soil-Structure Interaction Problems [PDF]
Engineering and Technology Journal, 2013 One of the major issues in the dynamic analysis of soil-structure interaction problems is to model the far field medium. The dynamic analysis of soil-structure interaction problems can be carried out by using a numerical solution procedure such as finite

Fast frequency response computation for Rayleigh damping [PDF]
International Journal for Numerical Methods in Engineering, 2007 AbstractWe present a model reduction Lanczos method for the computation of frequency response functions of Rayleigh damping problems. The connection with modal extraction and modal superposition is made. The usual model reduction methods require complex arithmetic. With the proposed method, complex arithmetic is only used for the reduced problem.

A Reduced-Order Model of Heat Transfer Effects on the Dynamics of Bubbles [PDF]
, 2002 The Rayleigh-Plesset equation has been used extensively to model spherical bubble dynamics, yet it has been shown that it cannot correctly capture damping effects due to mass and thermal diffusion.

Scaling laws for convection and jet speeds in the giant planets [PDF]
, 2010 Three-dimensional studies of convection in deep spherical shells have been used to test the hypothesis that the strong jet streams on Jupiter, Saturn, Uranus, and Neptune result from convection throughout the molecular envelopes.
