The objective of this study is to obtain the transient solution of the thermoelastic-plastic deformation of internal heat-generating tubes by considering the thermomechanical coupling effect and the temperature-dependent physical properties of the material. The previously developed steady-state model describing the elastic-plastic behavior of the tubes is modified to obtain the transient solution. The propagation of the elastic-plastic interface for a given heat load is obtained; and the corresponding stress, displacement, and plastic strain components are computed. The effect of the coupling is investigated using three different engineering materials, namely, steel, aluminum, and magnesium; and it has been found to be negligible. On the other hand, the temperature dependence of the mechanical and thermal properties affects the computed profiles significantly.

Quantum chemical investigation of thalidomide molecule Erkoç, Şakir; Erkoc, F (Elsevier BV, 2005-04-14) The structural and electronic properties of the thalidomide molecule have been investigated theoretically by performing semi-empirical molecular orbital (AM1) and density functional theory calculations. The geometry of the molecule has been optimized by AM1 method and the electronic properties of the molecule have been calculated by density functional theory in its ground state.
Analytical Solution of Nonlinear Strain Hardening Preheated Pressure Tube Eraslan, Ahmet Nedim (2008-01-01) The analytical solution of a nonlinear strain hardening preheated tube subjected to internal pressure is presented. A state of generalized plane strain, small deformations, and temperature gradients are assumed. The analytical plastic model is based on the incremental theory of plasticity, Tresca´s yield criterion, its associated flow rule, and a Swift-type nonlinear hardening law. Solutions for linearly hardening and perfectly plastic materials are also presented.
Theoretical investigation of melatonin and its hydroxy isomers Erkoc, A; Erkoc, F; Keskin, N (Elsevier BV, 2002-07-05) The structural and electronic properties of melatonin and its six hydroxy isomers have been investigated theoretically by performing semi-empirical and ab initio molecular orbital theory calculations. The geometry of the systems has been optimized considering the semi-empirical molecular orbital theory at the level of AM I, and the electronic properties of the systems have been calculated by ab initio RHF including full MP2 correlation correction in their ground state. Conclusions were drawn by comparing wi...
THEORY OF POLARIZED FLUORESCENCE FROM MOLECULAR PAIRS - FORSTER TRANSFER AT LARGE ELECTRONIC COUPLING KNOX, RS; GULEN, D (Wiley, 1993-01-01) Polarization properties of the fluorescence from a pair of identical molecules coupled electronically are examined on the basis of a stochastic Liouville equation formalism developed in 1979 by Rahman, Knox and Kenkre. The time development of polarization is calculated for random ensembles of rigid molecule pairs under initial conditions that represent either selective excitation or broad-band coherent excitation. We hold that the applicability of the Forster mechanism is not limited to cases of weak coupli...
Associative behaviour and effect of functional groups on the fluorescence of graphene oxide Ozcan, Sefika; Vempati, Sesha; Çırpan, Ali; Uyar, Tamer (Royal Society of Chemistry (RSC), 2018-01-01) We have juxtaposed the structural, vibrational and emission properties of graphene oxide (GO) with various degrees of reduction with and without a model dispersant, unveiling a strong associative behavior between GO sheets and the influence of H-bonds. The interlayer spacings are similar to 0.84 and 0.78 nm for the as prepared and reduced samples. -OH groups are predominantly effected by the photo-thermal reduction. Also we note some regeneration of > C=O and -COOH groups in reduced samples. Clear changes t...
