A framework for the analysis of damage and recovery characteristics of asphalt mixtures
(
Taylor & Francis
, 2020 , Article)
This study presents two approaches for evaluating damage and recovery characteristics of asphalt mixtures. The first approach focuses on determining damage by extracting recoverable viscoelastic strain that has no damage ...
Forced vibration characteristics of embedded graphene oxide powder reinforced metal foam nanocomposite plate in thermal environment
(
Elsevier
, 2021 , Article)
Dynamic behavior of a new class of nanocomposites consisted of metal foam as matrix and graphene oxide powders as reinforcement is presented in this study in the framework of forced vibration. Graphene oxide powders are ...
Combined direct oxy-combustion and concentrated solar supercritical carbon dioxide power system—Thermo, exergoeconomic, and quadruple optimization analyses
(
Hindawi
, 2022 , Article)
For the global future energy systems, concentrated solar power (CSP) and direct CO2 capture systems are of the most important key technologies, however, each of these systems has shortcomings. This study addresses the solar ...
A hybrid piezoelectric-electromagnetic energy harvester from vortex-induced vibrations in fluid-flow; the influence of boundary condition in tuning the harvester
(
Elsevier
, 2022 , Article)
In this paper, a hybrid piezoelectric-electromagnetic energy harvester is proposed to harvest energy from fluid flow around a bluff-body using vortex-induced vibration (VIV). The hybrid piezoelectric-electromagnetic harvester ...
Adaptive Electromagnetic Vibration Absorber for a Multimode Structure
(
Assoc. of Mechanical Eng. and Technicians of Slovenia
, 2022 , Article)
All structures experience vibrations due to external dynamic force excitations, such as earthquakes and wind loadings. At resonance, the impact of this natural dynamic force on structures may lead to structural failures. ...
Magnetorheological elastomer-based variable stiffness flexible coupling for vibration isolation
(
Canadian Science Publishing
, 2021 , Article)
Rotating mechanical equipment such as pumps and motors can suffer from unattenuated torsional vibration. The causes of such vibration range from imbalance within the rotating system to misalignment, or even operating at ...
