Use of triple beam resonant gauges in torque measurement transfer standard [PDF]

open access: yes, 2010
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A new torque transfer standard using metallic TBTF resonant sensor was developed to overcome the overload capability problem which occurs with conventional ...

Resonance Oscillations in a Hot Nonuniform Plasma Column [PDF]

open access: yesPhysical Review Letters, 1963
This Letter reports new observations of resonances in a low-density plasma column and a quantitative theory of the frequency spectrum which is in excellent agreement with these measurements. Other measurements have recently been reported by Dattner. (1)

A study of the low-cycle fatigue failure of a galvanised steel lighting column [PDF]

open access: yes, 2009
This paper presents the results of a low-cycle fatigue test on a galvanised steel lighting column. The aim of the test was to simulate the behaviour of the column undergoing large amplitude resonant vibration caused by wind.

Cyclotron resonance in a pure electron plasma column [PDF]

open access: yesPhysical Review Letters, 1991
We demonstrate experimentally the effects of plasma rotation and particle thermal velocities on cyclotron resonance in a long cylindrical pure electron plasma column of low density (ωp2≪ωc2). A single m=1 mode (eimθ-iωt) is found whose frequency ω is down-shifted from ωc=eB/me by an amount equal to the low-frequency diocotron mode frequency (〈ωp2〉/2ωc).

Shape, Resonant Frequency and Thermoelastic Dissipation Analysis of Free-Formed Microhemispherical Shells Based on Forming Process Modeling

open access: yesMicromachines, 2022
Free-form microhemispherical shell resonators have the advantages of high quality factor and mass production. The shape of microhemispherical shells created via this process is based on a single mold and is difficult to adjust, which affects the resonant

Macroscale signatures of crushing from resonant column tests [PDF]

open access: yesEPJ Web of Conferences
The resonant column apparatus has been widely used to measure the dynamic properties of particulate geomaterials, and to describe their variation as a function of confining stress and strain.

Laboratory Characterization of a Compacted–Unsaturated Silty Sand with Special Attention to Dynamic Behavior

open access: yesApplied Sciences, 2020
The dynamic properties of compacted non-cohesive soils are desired not only because of the risk of natural sources of dynamic excitations such as earthquakes, but mostly because of the anthropogenic impact of machines that are working on such soils ...

Low-amplitude dynamic tests of fine gravel in a resonant column [PDF]

open access: yesE3S Web of Conferences, 2019
Construction of industrial and civil buildings, taking into account the dynamic effects on the foundations, requires special experiments on the mechanical properties of soils. This article presents the results of studying the dynamic properties of coarse

The New Empirical Equation Describing Damping Phenomenon in Dynamically Loaded Subgrade Cohesive Soils

open access: yesApplied Sciences, 2019
The damping ratio (D) is one of the key soil parameters in geotechnical issues where the soil is subjected to dynamic loads, like machines foundation, city tram and subway traffic, and driving of sheet pile or precast pile.
