A new approach to investigate wave dissipation in viscoelastic tubes: Application of wave intensity analysis [PDF]

open access: yes, 2005
Wave dissipation in elastic and viscoelastic medium has been investigated extensively in the frequency domain. The aim of this study is to examine the pattern of wave dissipation in the time-domain using wave intensity analysis.

A five-parameter constitutive model for hysteresis shearing and energy dissipation of rock joints

open access: yesInternational Journal of Mining Science and Technology, 2022
Rock joints exhibit hysteresis shearing behavior and produce energy dissipation under shear cyclic loads, which however cannot be accurately depicted by existing constitutive models. This paper establishes a constitutive model for hysteresis shearing and

Influences of Depth of the Falling-sill on the Flow State Conversion of Underflow Hydraulic Jump

open access: yesRenmin Zhujiang, 2023
In restricted topographic conditions,a falling-sill can be set at the end of the discharge chute for the spillway.The length of the dissipation pool is shortened by increasing the flow velocity attenuation along the way of the jet,or increasing the ...

Structural Performance of R-Type Steel Damper Used in Reinforced Concrete Members

open access: yesApplied Sciences, 2021
This study proposes a steel damper with a simple shape and excellent energy dissipation capacity. The proposed damper has a rectangular shape (R-type) and has an energy dissipation part and a load transmission part. The energy dissipation part dissipates

Energy Dissipation and Fluctuation-Response in Driven Quantum Langevin Dynamics

open access: yes, 2008
Energy dissipation in a nonequilibrium steady state is studied in driven quantum Langevin systems. We study energy dissipation flow to thermal environment, and obtain a general formula for the average rate of energy dissipation using an autocorrelation ...

Excess energy and photosynthesis: responses to seasonal water limitations in co-occurring woody encroachers of the semi-arid Southern Great Plains

open access: yesPhotosynthetica, 2023
Woody plant areal encroachment is pervasive throughout the Southern Great Plains, USA. The ability of woody plants to dissipate excess solar radiation - dynamically over the day and sustained periods without recovery overnight -is key for maintaining ...
