Oblique surface cracking and crack closure in an orthotropic medium under contact loading
Toktaş, Selim Ercihan; Dağ, Serkan; Department of Mechanical Engineering (2018)
In this study, inclined surface cracks in an elastic orthotropic half-plane exposed to contact loading at the material surface are examined for both open and closed crack assumptions. At first, mixed mode stress intensity factors are computed for fully open crack assumption depending on the solution of singular integral equations, obtained by Full Fourier Transform techniques. Unless fully open crack assumption is valid, the suitable crack closure mode is determined. Both crack tip and full length closure m...
Performance of rectangular fins on a vertical base in free convection heat transfer
Yazıcıoğlu, Burak; Yüncü, Hafit; Department of Mechanical Engineering (2005)
The steady-state natural convection heat transfer from vertical rectangular fins extending perpendicularly from vertical rectangular base was investigated experimentally. The effects of geometric parameters and base-to-ambient temperature difference on the heat transfer performance of fin arrays were observed and the optimum fin separation values were determined. Two similar experimental set-ups were employed during experiments in order to take measurements from 30 different fin configurations having fin le...

Elastic analysis of a circumferential crack in an isotropic curved beam using modified mapping-collocation method
Amireghbali, Aydın; Çöker, Demirkan; Department of Aerospace Engineering (2013)
The modified mapping-collocation (MMC) method is applied to analyze a circumferential crack in an isotropic curved beam. Based on the method a MATLAB code was developed to obtain the stress field. Incorporating the stress correlation technique, the opening and sliding fracture mode stress intensity factors (SIF)s of the crack for the beam under pure bending moment load case are calculated. The MMC method aims to solve two-dimensional problems of linear elastic fracture mechanics (LEFM) by combining the powe...
