Dynamic response of functionally graded graphene nanoplatelet reinforced shells with porosity distributions under transverse dynamic loads
(
Institute of Physics Publishing
, 2019 , Article)
This article investigates forced vibrational characteristics of a porous nanocomposite shell reinforced by graphene platelets (GPLs) under radial dynamic loads. Material properties of the shell dependents on uniform and ...
Compact UWB band-notched antenna with integrated bluetooth for personal wireless communication and UWB applications
(
MDPI AG
, 2019 , Article)
A compact band-notched UWB (Ultra-Wide Band) antenna with integrated Bluetooth is developed for personal wireless communication and UWB applications. The antenna operates at the UWB frequency band (3.1-10.6 GHz) as well ...
Vibration of rotating functionally graded Timoshenko nano-beams with nonlinear thermal distribution
(
Taylor and Francis Inc.
, 2018 , Article)
The vibration analysis of rotating, functionally graded Timoshenko nano-beams under an in-plane nonlinear thermal loading is studied for the first time. The formulation is based on Eringen's nonlocal elasticity theory. ...
A combined method to model dynamic recrystallization based on cellular automaton and a phenomenological (CAP) approach
(
MDPI AG
, 2018 , Article)
Titanium alloys with high stacking-fault energy show continuous dynamic recrystallization (CDRX) instead of discontinuous dynamic recrystallization (DDRX) during high-temperature deformation. During the CDRX mechanism, new ...
Nonlinear free and forced vibrations of graphene nanoplatelet reinforced microbeams with geometrical imperfection
(
Springer Verlag
, 2019 , Article)
Nonlinear free/forced vibration of a functionally graded graphene nanoplatelet (GNP) reinforced microbeam having geometrical imperfection which is rested on a non-linear elastic substrate have been studied in the present ...
Investigation of the Effect of Larestan's Pipeline Water on the Mechanical Properties of Concretes Containing Granite Aggregates
(
Hindawi Limited
, 2019 , Article)
In this study, the compressive strength of the concretes made by the pipeline water of Larestan has been investigated. Although the used water for the concretes must be clean, standard, and generally drinkable water, in ...
Strain gradient based dynamic response analysis of heterogeneous cylindrical microshells with porosities under a moving load
(
Institute of Physics Publishing
, 2019 , Article)
Forced vibration of a porous functionally graded (FG) cylindrical microshell due to a moving point load with constant velocity is studied for the first time. Through the thickness of microshell, there are even-type or ...
Resonator based switching technique between ultra wide band (Uwb) and single/dual continuously tunable-notch behaviors in uwb radar for wireless vital signs monitoring
(
MDPI AG
, 2018 , Article)
This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna ...
Post-buckling analysis of piezo-magnetic nanobeams with geometrical imperfection and different piezoelectric contents
(
Springer Verlag
, 2019 , Article)
Thermal post-buckling behavior of a geometrically imperfect/perfect piezo-magnetic nano-scale beams made of two-phase composites is analyzed in the present paper based on nonlocal elasticity theory. For the first time, the ...
