A piezoelectric beam model with geometric, material and damping nonlinearities for energy harvesting
(IOP Publishing, 2020-09-10)
To predict electrical generation in piezoelectric small-scale beam energy harvesting devices, it is important to have a complete mathematical model that captures the different associated phenomena. In the literature, some ...
Civil Engineering Applications: Specific Properties of NiTi Thick Wires and Their Damping Capabilities, A Review
(Springer, 2017-12-04)
This study describes two investigations: first, the applicability of NiTi wires in the damping of oscillations induced by wind,rain, or traffic in cable-stayed bridges; and second, the characteristic properties of NiTi,i.e., ...
Viscoelastic properties and efficient acoustic damping in confined polymer nano-layers at GHz frequencie
(Nature Publishing Group, 2016-09-16)
We investigate the viscoelastic properties of confined molecular nano-layers by time resolved optical pump-probe measurements. Access to the elastic properties is provided by the damping time of acoustic eigenmodes of thin ...
Damping of vortex waves in a superfluid
(IOP Publishing, 2005-08)
The damping of vortex cyclotron modes is investigated within a generalized quantum theory of vortex waves. Similarly to the case of Kelvin modes, the friction coefficient turns out to be essentially unchanged under such ...
Damping off on soybean (Glycine max) caused by Pythium aphanidermatum in Buenos Aires Province (Argentina)Damping off en soja (Glycine max) causado por Pythium aphanidermatum en la provincia de Buenos Aires (Argentina)
(Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias, 2020-12-01)
Pythium aphanidermatum presenta una distribución cosmopolita, principalmente en las regiones cálidas del mundo. El objetivo de este trabajo fue identificar el agente causal del damping off en plántulas de soja en fechas ...
Superelastic damping at nanoscale in ternary and quaternary Cu-based shape memory alloys

Polymeric networks based on tung oil: reaction and modification with green oil monomers
(Elsevier, 2015-01-19)
A highly unsaturated vegetable oil (tung oil) was cationically copolymerized with a vegetable oil derived monomer, that replaces the more frequently used styrene. The synthesized comonomer was methyl ester of tung oil, ...
Exceptional point in a simple textbook example
(IOP Publishing, 2018-05)
We propose to introduce the concept of exceptional points in intermediate courses on mathematics and classical mechanics by means of simple textbook examples. The first one is an ordinary second-order differential equation ...
A semiempirical approach to a viscously damped oscillating sphere
(IOP Publishing, 2005-12)
A simple model of damped harmonic motion is usually presented in undergraduate physics textbooks and straightforwardly applied for a variety of well-known experiments in student laboratories. Results for the decaying ...
Damping micromechanisms for bones above room temperature
(Trans Tech Publications, 2014-03)
The wide damping maximum which is reported to appear in bones, involving bothcortical and cancellous parts, between around 280 K and 420 K; has been determined to be acomposition of different processes taking place at ...
