The thermoelastic-plastic deformations of internal heat-generating tubes are investigated by considering the temperature dependence of the thermal conductivity coefficient, Young's modulus, the coefficient of thermal expansion, and the yield limit of the material. A model describing the elastic-plastic behavior of the tube is developed. The model consists of a system of two second-order ordinary differential equations and a first-order ordinary differential equation involving nonlinear temperature-dependent coefficients. The computer solution of the model is obtained, and the results are compared with the analytical solution that assumes constant thermomechanical properties. It is found that the difference between the two solutions becomes significant in the regions of high temperatures.

Thermal contact conductance of nominaly flat surfaces
Yüncü, Hafit (2006-11-01)
The variation of thermal conductance of contact has been investigated as a function of apparent contact pressure experimentally. Experimental data has been obtained for steel, brass, copper and aluminum test pieces having different surface roughness over a wide range of contact pressures. Experimental results are compared with the theoretical predictions of an existing theory. Comparison revealed good agreement of trend with the experimental data, however, numerical values vary widely. Theory can predict th...
Elastic-plastic deformation of a heat generating tube with temperature-dependent yield stress
Gulgec, M; Orcan, Y (2000-01-01)
The distribution of stress, plastic strain and displacement in an elastic-perfectly plastic tube with fixed ends in the presence of a uniform heat source is investigated analytically by taking into consideration the temperature dependence of the yield limit. The treatment is based on Tresca's yield condition and its associated flow rule. Depending on the radius ratio of the tube, in general, five different plastic regions, two of them corresponding to an edge regime of Tresca's prism, and an intermediate el...
Experimental thermal performance characterization of flat grooved heat pipes
Alijani, Hossein; Çetin, Barbaros; Akkuş, Yiğit; Dursunkaya, Zafer (TAYLOR & FRANCIS INC, 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA, 2015-06-15)
The thermal characterization of aluminum flat grooved heat pipes is performed experimentally for different groove dimensions. Three heat pipes with groove widths of 0.2 mm, 0.4 mm, and 1.5 mm are used in the experiments. The effect of the amount of the working fluid is extensively studied for each groove width. The results reveal that, although all three succeed in dissipating the heat input through the phase change of the working fluid by continuous evaporation and condensation, the effectiveness of the he...
ELECTRICAL RESISTIVITIES OF LIQUID AL-MG AND AL-CU ALLOYS
KHAJIL, TMA; Tomak, Mehmet (1989-05-01)
The electrical resistivity of liquid Al−Mg and Al−Cu alloys is calculated using both the Faber-Ziman and «2k F» scattering theories. The partial structure factors are described by the hard-sphere system. The calculated resistivity values are in qualitative agreement with available experimental data.
Thermal stress problems ın FGMS
Akdoğan, Esra Nur; Kadıoğlu, Fevzi Suat; Department of Mechanical Engineering (2019)
In this thesis transient temperature distribution, thermal stresses and thermal stress intensity factors (TSIFs) of an infinitely long functionally graded material (FGM) strip containing periodic cracks under thermal shock are studied. Thermal shock is applied by imposing a sudden change in the boundary temperatures. Solution of the present thermoelasticity problem is considered in three successive steps. First the thermal (conduction) problem is solved and the transient temperature distribution is determin...
