Failure analysis of trapezium shaped carbon-epoxy plate pinned-joint
(2000)
Bu çalışmanın amacı, içinde pim bulunan yamuk şekilli, karbon-epoksi kompozitinin yırtılma mukavemetini ve modunu araştırmaktır. Yırtılma yükü ve modu nümerik olarak analiz edildi. Nümerik metod iki adım içerir: İlk olarak ...
İki tarafında dairesel boşluk bulunan levhada gerilme şiddeti faktörlerinin ve çatlak ilerleme yönünün bulunması
(2001)
Bu çalışmada iki tarafında dairesel boşluğa sahip, bir dairesel boşluk üzerinde 2 mm uzunluğunda çatlak bulunan alüminyum levhanın gerilme şiddeti faktörleri (GŞF) ve çatlak ilerleme yönü sonlu elemanlar metodu (SEM) ...
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 ...
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, ...
Modeling of the vibrations caused by ball bearing defects
(2003)
In this study a shaft-ball bearing system is modeled in order to investigate the vibrations of ball bearings with running surfaces defects. Shaft and bearing was modeled as mass-spring system and balls were assumed have ...
Determination of rolling element bearing defects through vibration analysis
(2003)
Determination of rolling element bearing defects through the available vibration analysis method is studied in this paper. Rolling element bearing defect vibrations, vibration measurement and their analysis is briefly ...
Determination of physical faults in gearbox through vibration analysis
(2003)
Gears are important machine elements that provide motion or power transmission. Accuracy and quality of work done is directly related to the continuous motion transmission in a machine. Therefore, the determination of ...
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 ...
Analysis of free and forced vibration of a cracked cantilever beam
(Elsevier Sci Ltd, 2007)
Structures are weakened by cracks. When the crack size increases in course of time, the structure becomes weaker than its previous condition. Finally, the structure may breakdown due to a minute crack. Therefore, crack ...
