Development of a regression model for the fatigue life assessment of open-hole specimens with double through the thickness cracks Heidari Shabestari, Seyed Sohrab; Kayran, Altan; Department of Aerospace Engineering (2019) This thesis mainly deals with the investigation of the fatigue crack growth characteristics of open rivet holes in aluminum 2024-T3 material. In this respect, most commonly observed type of cracks emanating from rivet holes, namely, double through the thickness edge cracks with centered configurations has been considered. Stress intensity factors and the fatigue lifes are calculated analytically and also with the Extended Finite Element Method (XFEM).Analytical calculations have been carried out using the c...
Development of a computer program for the analysis of fatigue crack growth Dalgıç, Ali Murtaza; Bilir, Ömer Gündüz; Kadıoğlu, Suat; Department of Mechanical Engineering (2002) In this study, a computer program is developed for fatigue crack propagation analysis of metal alloys and random fiber composites. The developed program takes the fatigue crack propagation experiment data in the form of crack length vs. number of cycles from the user. The user also, selects the crack geometry and defines loading conditions of the test specimen. Developed program analyze the experimental data and evaluates crack growth rate and stress intensity range. For the calculated or ready crack growth...
Development of a Parametric Equation to Predict the Joint Shear Strength Burak Bakır, Burcu (American Society of Civil Engineers (ASCE), 2013-05-01) This paper presents an analytical study that focuses on the development ofa parametric equation to predict the joint shear strength. In this analytical study, adatabase containing geometric properties, material strengths, configuration detailsand test results of reinforced concrete beam-to-column connection subassembliestested under cyclic loading is established. Then, based on the experimental results,parameters affecting joint shear capacity are determined. The most influentialparameters are selected and ...
A simulation study on the comparison of methods for the analysis of longitudinal count data İnan, Gül; İlk Dağ, Özlem; Department of Statistics (2009) The longitudinal feature of measurements and counting process of responses motivate the regression models for longitudinal count data (LCD) to take into account the phenomenons such as within-subject association and overdispersion. One common problem in longitudinal studies is the missing data problem, which adds additional difficulties into the analysis. The missingness can be handled with missing data techniques. However, the amount of missingness in the data and the missingness mechanism that the data ha...
DEVELOPMENT OF AN INTERFEROMETRIC TECHNIQUE TO BE USED IN MEASURING MICRON LEVEL CLEARANCES FILLED WITH A LUBRICANT Yildirim, Murat; Dursunkaya, Zafer; Okutucu Özyurt, Hanife Tuba (2009-10-21) The aim of this study is to develop an interferometric technique to measure micron level clearances occurring in small piston-cylinder arrangements; such as hermetically sealed compressors. A Cartesian model of the piston cylinder arrangement is manufactured and lateral and vertical motions are generated via a step motor, and micrometers, respectively, to simulate the piston motion and the change of clearance during the motion. Experiments are conducted in air and a lubricant. Measurements show the importan...
