Analytical Estimations of Strength of Two Layer Coating Loaded along a Line

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2017
The engineering calculation procedure of the stress-strain state of the two-layer coating under the load localized along a line is proposed. The plane coupled problem of the plate equilibrium has been formulated.

Effect of Soil Damping on the Soil–Pile–Structure Interaction Analyses in Cohesionless Soils

open access: yesApplied Sciences, 2022
Pile foundations in earthquake-prone regions must be analyzed and designed considering the dynamic loads. In the fully nonlinear dynamic analyses, the soil nonlinearity can be considered using the modulus degradation curves in the total-stress approach ...

Damping rates of hot Giant Dipole Resonances [PDF]

open access: yes, 1998
The damping rate of hot giant dipole resonances (GDR) is investigated. Besides Landau damping we consider collisions and density fluctuations as contributions to the damping of GDR.

Thermally damped linear compressional waves in a 2D solar coronal model [PDF]

open access: yes, 2007
The high resolution observations (TRACE and SOHO) of waves in coronal structures have revealed a rapid damping of modes, sometimes their damping length being of the same order as their wavelength. The rapid damping of modes in coronal loops permits us to

Estimation of Damping for a Double-Layer Grid Using Input-Output and Output-Only Modal Identification Techniques [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2020
In large civil engineering structures, the output-only modal identification is the most applicable technique for estimating the modal parameters such as damping.

Damping Mechanisms

open access: yes, 2014
Chapter 6 The term damping is used to describe the means by which oscillation amplitudes are reduced through irreversible removal of vibratory energy in a mechanical system or a component. Dissipation, on the other hand, refers to the mechanism by which irreversible energy transfer, from vibratory to thermal, takes place.

Effect of Damping on the Natural Frequencies of Linear Dynamic Systems [PDF]

open access: yes, 1961
An analysis is presented of the effect of weak damping on the natural frequencies of linear dynamic systems. It is shown that the highest natural frequency is always decreased by damping, but the lower natural frequencies may either increase or decrease,

BUS BAR DAMPING IS A WAY OF INCREASING THE VIBRATION RELIABILITY OF TURBOGENERATOR STATORS

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2019
: The work is devoted to the consideration of the bus bar ring damping of turbogenerator stators. The urgency of the problem of ensuring the vibrational reliability of high-power turbogenerator stators is shown.
