Analytical solutions are obtained for thermally induced axisymmetric elastic and elastic-plastic deformations in nonuniform heat-generating composite tubes with fixed ends. Thermoelastic solutions are obtained using four different boundary conditions: (i) free, (ii) radially constrained and free, (iii) free and pressurized, (iv) free and radially constrained. Elastic-plastic solutions are obtained for a composite tube having free inner and radially constrained outer boundaries using Tresca's yield condition and its associated flow rule. The first two stages of elastic-plastic deformations are studied considering nonlinearly hardening, linearly hardening, and perfectly plastic material behavior. The theory developed is illustrated in several numerical examples.

Thermal fracture analysis of orthotropic functionally graded materials using an equivalent domain integral approach Dağ, Serkan (2006-12-01) A new computational method based on the equivalent domain integral (EDI) is developed for mode I fracture analysis of orthotropic functionally graded materials (FGMs) subjected to thermal stresses. By using the constitutive relations of plane orthotropic thermoelasticity, generalized definition of the J-integral is converted to an equivalent domain integral to calculate the thermal stress intensity factor. In the formulation of the EDI approach, all the required thermomechanical properties are assumed to ha...
Stress distributions in energy generating two-layer tubes subjected to free and radially constrained boundary conditions Eraslan, Ahmet Nedim; Argeso, H (Elsevier BV, 2003-03-01) Analytical solutions are obtained for thermally induced axisymmetric elastic and elastic-plastic deformations in heat generating composite tubes having a free inner and a radially constrained outer boundaries. Tresca's yield condition and its associated flow rule are used to determine the elastic-plastic response of the assembly. Depending on the physical properties of the materials used, eight different plastic regions with different mathematical forms of the yield condition may occur in the assembly. The ...
Deformation Analysis of Elastic-Plastic Two Layer Tubes Subject to Pressure: an Analytical Approach Eraslan, Ahmet Nedim (2004-06-01) Analytical solutions are obtained for axisymmetric elastic-plastic deformations in tightly fitted concentric tubes with fixed ends subjected to either internal or external pressure. Tresca's yield criterion and its associated flow rule are used to estimate the elastic-plastic response of the assembly. The closed form solutions for all elastic-plastic deformation stages are obtained by assuming linear hardening material behavior. Some numerical examples are handled using the mechanical properties of real eng...
Electroactive macromonomers based on pyrrole and thiophene: a versatile route to conducting block and graft polymers Yagci, Y; Toppare, Levent Kamil (Wiley, 2003-10-01) The synthesis of block and graft copolymers containing insulating and conducting polypyrrole or polythiophene segments via a two-step procedure is described. Synthetic pathways to prepare pyrrole and thiophene functional macromonomers involving conventional and controlled/living polymerizations such as anionic and cationic ring opening, atom transfer radical polymerization are discussed. The use of these macromonomers in subsequent electrochemical and chemical polymerizations, leading to the formation of co...
Induced Current Magnetic Resonance Electrical Conductivity Imaging With Oscillating Gradients Eroglu, Hasan H.; Sadighi, Mehdi; Eyüboğlu, Behçet Murat (2018-07-01) In this paper, induced current magnetic resonance electrical impedance tomography (ICMREIT) by means of current induction due to time-varying gradient fields of magnetic resonance imaging (MRI) systems is proposed. Eddy current and secondary magnetic flux density distributions are calculated for a numerical model composed of a z-gradient coil and a cylindrical conductor. An MRI pulse sequence is developed for the experimental evaluation of ICMREIT on a 3T MRI scanner. A relationship between the secondary ma...
