A micro-continuum-mechanical material model for failure of rubber-like materials: Application to ageing-induced fracturing
Dal, Hüsnü (2009-08-01)
Rubbery polymers are subjected to severe environmental conditions under service. As a consequence of various ageing mechanisms, the outer surface of rubber components hardens in time and cracking occurs as a result of combined mechanical and chemical processes. Conventional phenomenological hyperelastic constitutive models do not account for material softening. Consequently, the stored energy and stresses tend to infinity as stretch increases. In this contribution, a network alteration for the ageing mechan...
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...
A deep learning methodology for the flow field prediction around airfoils
Duru, Cihat; Baran, Özgür Uğraş; Alemdar, Hande; Department of Mechanical Engineering (2021-9-07)
This study aims to predict flow fields around airfoils using a deep learning methodology based on an encoder-decoder convolutional neural network. Neural network training and evaluation are performed from a set of computational fluid dynamics (CFD) solutions of the 2-D flow field around a group of known airfoils at a wide range of angles of attack. Reynolds averaged Navier-Stokes (RANS)-based CFD simulations are performed at a selected Mach number on the transonic regime on high-quality structured computati...
A deep learning approach for the transonic flow field predictions around airfoils
Duru, Cihat; Alemdar, Hande; Baran, Özgür Uğraş (2022-01-01)
Learning from data offers new opportunities for developing computational methods in research fields, such as fluid dynamics, which constantly accumulate a large amount of data. This study presents a deep learning approach for the transonic flow field predictions around airfoils. The physics of transonic flow is integrated into the neural network model by utilizing Reynolds-averaged Navier–Stokes (RANS) simulations. A detailed investigation on the performance of the model is made both qualitatively and quant...
A Usability Study of WebMaps with Eye Tracking Tool: The Effects of Iconic Representation of Information
Alacam, Özge; Dalci, Mustafa (2009-07-24)
In this study, we aim to conduct usability tests on different WebMap sites with eye movement analysis. Overall task performance, the effects of iconic representation of information, and the efficiency of pop-up usage were evaluated. The eye tracking technology is used for this Study in order to follow the position of the users' eye-gaze. The results show that there are remarkable differences in task performance between WebMaps. Addition, they also differ in the use of iconic representations according to res...
