The importance of mesh modeling in the calculation of stress intensity factor
(2001)
In this paper, stress intensity factor (SIF) of an infinite plate with a center notched hole is calculated by means of finite element method (FEM) using both triangular quadratic element (TQE) and triangular quarter point ...
Investigation of ball vibrations in angular contact ball bearings
(2004)
In this study, a shaft-bearing model is developed in order to investigate ball vibrations in case of defected and undefected ball bearings. In this model, shaft-bearing couple is considered as a mass-spring system and balls ...
Heat transfer to a power-law fluid in arbitrary cross-sectional ducts
(2002)
Numerical solutions for laminar heat transfer of a non-Newtonian fluid in the thermal entrance region for triangular, square, sinusoidal, etc. ducts are presented for constant wall temperature. The continuity equation and ...
Statistical analysis of fracture strength of composite materials using Weibull distribution
(2002)
In this study, the fracture strength of a carbon-epoxy composite plate has been statistically analysed by Weibull distribution. Nineteen tension tests were carried out. The results obtained vary between 439 MPa and 552 ...
A new method for extracting 3D solid models of objects using 2D technical drawings
(2007)
In this study, a new method called "3D-Space" have been developed to obtain 3D models of prismatic machine parts using 2D technical drawings. The algorithm basicaly works in the following manner: 3 basic views (i.e. top, ...
Data extraction from CAD model for rotational parts to be machined at turning centres
(Scientific and Technical Research Council of Turkey, Ankara, Turkey, 1999)
Among the most important data produced and stored is product data. CAD data forms one of many contributors to product data. Although in most circumstances CAD data can be processed within the CIM environment by integrated ...
Investigatıon Of Mechanical Properties Of Carbon Fibre/Epoxy Composites Incorporating Nanoclay And Multi Walled Carbon Nanotube
(Serban Solacolu Foundation, 2017)
This study was conducted for the purpose of examining the mechanical relations of the multi-walled carbon nanotube (MWCNT) and the nanoclay (NC) with each other on the carbon fiber composite materials. Samples were prepared ...
The effect of ethanol-gasoline blends on performance and exhaust emissions of a spark ignition engine through exergy analysis
(Pergamon-Elsevier Science Ltd, 2017)
Ethanol which is considered as an environmentally cleaner alternative to fossil fuels is used on its own or blended with other fuels in different ratios. In this study, ethanol which has high octane rating, low exhaust ...
Investigation of the effects of gasoline and CNG fuels on a dual sequential ignition engine at low and high load conditions
(Elsevier Sci Ltd, 2018)
In this study, a dual sequential spark ignition engine is separately tested either with gasoline or CNG at low and high loads. In addition, numerical engine analyses are performed by constructing a 1-D engine model in ...
Investigation of Thermal Conductivity of Ceramic Cuttin Edge Based Sialon- Si3N4
(Gazi Univ, 2018)
High speed processing of ferrous or non-ferrous metal products used cutting edge can be produced from high-tech ceramics. Used as a cutting tool in the study Sialon(KY 2000) and silicon nitride(KY3500) (Si3N4) based thermal ...
