In this theoretical investigation, analytical solutions to thermally induced elastic and partially plastic deformations of a solid cylinder under periodic internal heat generation are derived. The analytical unsteady temperature distribution in the cylinder is formulated by the use of Duhamel’s theorem. Tresca’s yield criteria and the corresponding flow rules are utilized in the treatment of plastic deformation. Furthermore, the material of the cylinder is assumed to behave linearly during hardening. In both elastic and partially plastic deformations a state of generalized plane strain is taken into account. It is observed that the surface of the cylinder is critical and plastic deformation always commences there. It is also observed that the evolution of two adjacent plastic regions halt as soon as the temperature gradient reaches it’s maximum and just begins to draw back.

Implementation and comparison of reconstruction algorithms for magnetic resonance-electric impedance tomography (mr-eit) Martin Lorca, Dario; Eyüboğlu, Behçet Murat; Department of Biomedical Engineering (2007) In magnetic resonance electrical impedance tomography (MR-EIT), crosssectional images of a conductivity distribution are reconstructed. When current is injected to a conductor, it generates a magnetic field, which can be measured by a magnetic resonance imaging (MRI) scanner. MR-EIT reconstruction algorithms can be grouped into two: current density based reconstruction algorithms (Type-I) and magnetic flux density based reconstruction algorithms (Type-II). The aim of this study is to implement a series of r...
Computer simulation of grain boundary grooving and cathode voiding n bamboo interconnects by surface diffusion under capillary and electromigration forces Akyıldız, Öncü; Oğurtanı, Tarık Ö.; Department of Metallurgical and Materials Engineering (2004) The processes of grain boundary grooving and cathode voiding which are important in determining the life times of thin films connecting the transistors in an integrated circuit are investigated by introducing a new mathematical model, which flows from the fundamental postulates of irreversible thermodynamics, accounting for the effects of applied electric field and thermal stresses. The extensive computer studies on the triple junction displacement dynamics shows that it obeys the first order reaction kinet...
Karbon Nanotüplerle Süperkapasitörlerin Geliştirilmesi Ünalan, Hüsnü Emrah; Durucan, Caner; Çırpan, Ali(2017) Karbon nanotüplerin (KNT’ lerin) metallere yakın iletkenlikleri, yüksek yüzey alanları ve fonksiyonelleştirilebilir yüzey morfolojisine sahip olmaları süperkapasitör elektrotu olarak kullanılmalarının itici gücüdür. Ancak, KNT esaslı süperkapasitörlerin, metal oksit ve iletken polimerlere göre daha düşük enerji depolama kapasitesine sahip olduğunu belirtmiştir. Öte yandan metal oksitler ve iletken polimerler üzerine yapılan çalışmalar metal oksitlerin düşük iletkenliğini ve iletken polimerlerin mekanik daya...
Thermoelectric effects in menososcopic physics Çipiloğlu, M. Ali; Turgut, Sadi; Department of Physics (2004) The electrical and thermal conductance and the Seebeck coefficient are calculated for one-dimensional systems, and their behavior as a function of temperature and chemical potential is investigated. It is shown that the conductances are proportional to an average of the transmission probability around the Fermi level with the average taken for the thermal conductance being over a wider range. This has the effect of creating less well-defined plateaus for thermal-conductance quantization experiments. For wea...
A Numerical approach for the solutions of fluid dynamics problems in the presence of magnetic field Oğlakkaya, Fatma Sidre; Bozkaya, Canan; Department of Mathematics (2018) This thesis is conducted to investigate numerically the two-dimensional steady or unsteady, laminar flow of viscous, incompressible and electrically conducting fluids in complex geometries subject to either uniform inclined magnetic field or nodal magnetic sources. Specifically, the hydromagnetic natural/mixed convection of either conventional fluid or water-based nanofluid flow and the heat transfer are considered in irregular enclosures with wavy walls. The equations governing the steady magnetohydrodynam...
