Failure analysis of graphene sheets with multiple Stone-Thrower-Wales defects using molecular mechanics based nonlinear finite element models
(Hitit Üniversitesi Fen Bilimleri Enstitüsü, 2018-06-09)
Experimental studies show that Stone-Thrower-Wales (STW) defects generally exist in graphene sheets (GSs) and these defects considerably affect the fracture strength of GSs. Thus, prediction of failure modes of GSs with ...
Exergy destruction analysis of a gas turbine power plant
(Hitit Üniversitesi Fen Bilimleri Enstitüsü, 2018)
According to the data released by “Republic of Turkey-the Ministry of Energy and Nat ural Resources”, by the end of July 2017, 34% of the electricity of Turkey was produced from natural gas. As it is compared to ...
Predicting microstructure evolution during directed energy deposition additive manufacturing of Ti-6Al-4V
(American Society of Mechanical Engineers (ASME), 2018)
Laser engineering net shaping (LENS) is one of the representative processes of directed energy deposition (DED) in which a moving heat source having high-intensity melts and fuses metal powders together to print parts. The ...
Theoretical and experimental analysis for the impact response of glass fibre reinforced aluminium honeycomb sandwiches
(SAGE Publications Ltd, 2018)
Honeycomb sandwich structures are increasingly used in the automotive, aerospace and shipbuilding industries where fuel savings, increase in load carrying capacity, vehicle safety and decrease in gas emissions are very ...
Properties and tribologic behavior of titanium carbide coatings on AISI D2 steel deposited by thermoreactive diffusion
(Minerals, Metals and Materials Society, 2018)
In the present study, the metallographic, mechanical and tribologic behaviors of AISI D2 steel specimens coated with TiC through the titanizing process were investigated. The titanizing treatment was performed at the ...
A comparative study on the effects of different thermochemical coating techniques on corrosion resistance of STKM-13A steel
(Springer Boston, 2018)
The corrosion resistances of three different thermochemical coatings (grown using titanizing, boriding, and borotitanizing treatments) applied to STKM-13A steel surfaces were investigated. The coatings were characterized ...
Investigation of the component exergy efficiencies of a two stage vapour compression cycle
(Inderscience Enterprises Ltd., 2018)
The exergy efficiencies of the components (compressor I and II, condenser, evaporator and flash tank) of a two stage vapour compression refrigeration cycle were analysed with respect to evaporator and condenser temperatures ...
Design and implementation of real time monitoring and control system for distributed robotic systems supported with IOS/android application
(Strojarski Facultet, 2018)
In this study, a real time monitoring and control of the working parameters of distributed robotic systems used in manufacturing processes is presented. Additionally, a fault diagnosis and protection system is developed ...
High temperature wear behavior of the surface-modified externally cooled rolls
(Elsevier B.V., 2018)
Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ...
Experimental investigation of heat transfer from different pin fin in a rectangular channel
(Taylor and Francis Ltd., 2018)
In this study, the effect of both hexagonal pin fins (HPFs) and cylindrical pin fins (CPFs) into the rectangular channel on heat transfer augmentation, Nusselt number and friction factor were experimentally investigated. ...
