Time-dependent thermo-creep analysis of rotating FGM thick-walled cylindrical pressure vessels under heat flux

Stress Analysis for Cylinder Made of FGM and Subjected to Thermo-Mechanical Loadings

“…The authors in [20] had assumed that the pressure vessel was subjected only to the internal pressure, thus T i = T o and, consequently, T(r) = 0, to obtain the mechanical solution. By combining Equations (1), (4)- (6), besides applying the boundary conditions from Equation (7), the mechanical radial, hoop, and axial stresses and the axial strain could be obtained [20].…”

“…They have obtained results in a good agreement with the quasi-3D solution obtained considering mathematical layers with constant properties in the FGM layer and using high orders of expansion. Moreover, Nejad et al [6] investigated the time-dependent thermoelastic creep response for isotropic rotating thick-walled cylindrical pressure vessels made of functionally-graded material. They assumed that material properties were a function of the radius of the cylinder and that the Poisson s ratio was constant, and the creep stresses, creep strains, and radial displacement were plotted against dimensionless radius and time for different values of the powers of the material properties.…”

Micromechanical Simulation of Thermal Cyclic Behavior of ZrO2/Ti Functionally Graded Thermal Barrier Coatings

“…From the viewpoints of what kinds of inelastic deformations for each phase to be taken into account, some studies [17] considered plastic deformation of metal phase, which is the time-independent deformation, and some studies [18] took into consideration time-dependent deformation such as creep in FG TBC plates, for which the constitutive relations derived from experimental results were used. Recently, micromechanical approach considering plastic deformation of metal phase and creep of metal and ceramic phase as well as diffusional mass flow at the interface between metal and ceramic phases is proposed by the author [5].…”

Thermo-elastic analysis of axially functionally graded rotating thick cylindrical pressure vessels with variable thickness under mechanical loading

“…On other hand, thick shells involving cylindrical pressure vessels, in recent years, are widely used in space vehicles, aircrafts, nuclear power plants and many other engineering application (Nejad, Jabbari, & Ghannad, 2015a, 2015b, 2015c. A number of papers considering various aspects of cylindrical vessels have been investigated under various assumptions and conditions (Nejad & Kashkoli, 2014;Wu & Wang, 2015;Tokovyy & Ma, 2015).…”

“…They observed that FSDT method has acceptable results, but the radial and von Mises stresses resulted from FSDT show a significant difference by the results calculated from HSDT and FEM solution. Nejad and Kashkoli (2014) investigated time-dependent thermo-elastic creep response for isotropic rotating thick-walled cylindrical pressure vessels made of FGM, taking into account the creep behavior of the pressure vessels, as described in Norton's model. Zenkour and Abbas (2014) discussed the problem of generalized thermoelasticity with one relaxation time for an infinite annular cylinder of temperature dependent physical properties.…”
