The effects of material nonhomogeneity and nonisothermal conditions on the stress response of pressurized tubes are assessed by virtue of a computational model. The modulus of elasticity, the Poisson's ratio, the yield strength, and the coefficient of thermal expansion, are assumed to vary nonlinearly in the tube. A logarithmic temperature distribution within the tube is proposed. Under these conditions, it is shown that the stress states and the magnitudes of response variables are affected significantly by both the material nonhomogeneity and the existence of the radial temperature gradient.

Computer Solutions of Plane Strain Axisymmetric Thermomechanical Problems Eraslan, Ahmet Nedim (2005-08-01) A simple computational model is developed to estimate elastic, elastic-plastic, fully plastic, and residual stress states in generalized plane strain axisymmetric structures considering temperature dependent physical properties as well as nonlinear isotropic strain hardening. Using the von Mises yield criterion, total deformation theory and a Swift-type nonlinear hardening law, a single nonlinear differential equation governing thermoelastoplastic behavior is obtained. A shooting technique using Newton iter...
On the use of temperature-dependent physical properties in thermomechanical calculations for solid and hollow cylinders Argeso, Hakan; Eraslan, Ahmet Nedim (2008-02-01) The use of temperature-dependent physical properties in estimating the thermoelastic response of cylinders and tubes is assessed. A computational model in cylindrical polar coordinates is constructed for this purpose. The model incorporates experimental data to describe the temperature dependency of the modulus of elasticity E, the Poisson's ratio v, the yield strength sigma(0), the coefficient of thermal expansion alpha, and the thermal conductivity k of steel. Various numerical examples, including plane s...
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...
DEFORMATION ANALYSIS OF TWO LAYER COMPOSITE TUBES UNDER CYCLIC LOADING OF EXTERNAL PRESSURE Eraslan, Ahmet Nedim (2016-01-01) The stress response of axially constrained two-layer composite tubes under cyclic loading of external pressure is investigated in this study. Elastic and elastoplastic stress states for the tube assemblies are examined by developing a mathematical model based on Tresca's yield criterion, its associated ow rule, and linear strain hardening. Using this model, the composite tubes with different dimensions are analyzed under one cycle of loading, unloading, and reloading of external pressure. It is observed tha...
Yielding and Elastoplastic Deformation of Annular Disks of a Parabolic Section Subject to External Compression Akgül, Ferhat (2005-01-01) A computational model is developed to predict partially plastic stresses in variable thickness annular disks subject to radial compression. The model is based on the von Mises' yield criterion, deformation theory of plasticity and a Swift type hardening law. Considering a thickness profile in the form of a general parabolic function, the condition of occurrence of plastic deformation at the inner and outer edges of the annular disk is investigated. A critical disk profile is determined and the corresponding...
