Thermoelastic stress response of a periodic heat generating solid cylinder is investigated by analytical means. The cylinder is initially at zero temperature. For times greater than zero, heat is generated internally and slowly at a time dependent rate. Two periodic heat generation rates are used. The temperature distribution in the solid cylinder corresponding to each generation rate is obtained by making use of Duhamel’s theorem. An uncoupled thermoelastic solution of the solid cylinder is then obtained under generalized plane strain condition. The effects of various parameters on the stress and deformation behavior of the cylinder are studied and presented in graphical forms.

Analysis of stress in the elastic state in a solid cylinder subjected to periodic boundary condition
Yedekçi, Buşra; Eraslan, Ahmet Nedim; Department of Engineering Sciences (2015)
An analytical model is developed to investigate the thermoelastic response of a solid cylinder subjected to periodic boundary condition. Time dependent periodic boundary condition for the solid cylinder is treated by the help of Duhamel's theorem. The corresponding thermoelastic equation is obtained in terms of radial displacement by using basic equations of elasticity under generalized plane strain presupposition. Analytical solution of the thermoelastic equation is obtained to determine the distributions ...
Analyses of elastic limit heat loads in thick walled tubes subjected to periodic surface temperatures: analytical treatment
APATAY, TUNÇ; Eraslan, Ahmet Nedim (2018-01-01)
ANALYTICAL SOLUTIONS ARE DERIVED TO ANALYZE elastic limit heat loads in tubes subjected to periodic surface temperatures. The tube is initially at zero temperature and for the times greater than zero one of the surfaces of the cylinder is subject to a periodic boundary condition while the other surface is insulated. For the transient temperature distribution, the heat conduction equation is solved by using Duhamel's theorem. The uncoupled theory of thermoelasticity is used as the cylinder is heated or coole...
Calculation of the Dielectric Constant of a Ferroelectric Liquid Crystal From a Mean Field Model
YURTSEVEN, HASAN HAMİT; Yurtseven, Hasan Hamit (2011-01-01)
The static dielectric constant epsilon(perpendicular to) of the ferroelectric liquid crystal 4-(3-methyl-2-chlorobutanoyloxy)-4'--heptyloxybiphenyl (A7) with high spontaneous polarization is calculated as a function of temperature using a mean field model. This calculation is performed close to the smectic A-isotropic liquid (SmA-I) transition for pure optically active compound (T-c = 81.6 degrees C). For this calculation of epsilon(perpendicular to), the free energy of the SmA phase is expanded in terms of...
Analysis of Local Thermal Equilibrium Assumption in Transient Forced Convection in a Graphite Foam Channel
Gürüf, Gürşah; Solmaz, İsmail; Bayer, Özgür (2020-12-01)
In this study, the validity of Local Thermal Equilibrium (LTE) assumption in the transient forced convection of a rectangular channel filled with a block of graphite foam is examined numerically. The governing macroscopic energy conservation equations for solid and gas phases are derived by taking the average of the microscopic one over the averaging volume. Initially, LTE is in existence between the phases and then, the fluid temperature at the channel inlet is suddenly raised. Besides, an appropriate insu...
EVALUATION OF SECOND VIRIAL COEFFICIENTS FROM SATURATION DATA
Orbey, H.; Orbey, N. (Informa UK Limited, 1989-3)
A data reduction technique is introduced for the evaluation of second virial coefficients of gases at subcritical temperatures. The method makes use of the vapor-liquid equilibrium data, i.e., temperature, saturation pressure, liquid and vapor molar volumes and can be used to obtain second virial coefficients of a wide variety of fluids including polar, associating and quantum gases. The calculated second virial coefficients are in good agreement with their counterparts from literature, which are obtained f...
