Quantification of modeling uncertainty in the Rayleigh damping model

Earthquake Engineering & Structural Dynamics
AbstractUnderstanding and accurately characterizing energy dissipation mechanisms in civil structures during earthquakes is an important element of seismic assessment and design. The most commonly used model is attributed to Rayleigh. This paper proposes a systematic approach to quantify the uncertainty associated with Rayleigh's damping model ...

Dynamics of a cross beam with a straight crack in a mining linear vibrating screen

Heliyon
Cross beam fracture is one of the common failures of vibrating screens, and crack is the early manifestation of fracture, which is hard to detect. In order to meet the screening requirement of the vibrating screen and improve the service life of the ...

Time history response analysis using extended Rayleigh damping model

Procedia Engineering, 2017
Abstract Rayleigh damping has been widely used in time history response analysis. Many articles have reported the problems associated with this damping and suggested remedies. A basic problem is that the frequency area across which the damping ratio is almost constant is too narrow.

Fast frequency response computation for Rayleigh damping

, 2006
We 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.
