“…Çallıoğlu et al (2011) analytically handled the thermoelastic analysis of power-law graded stress-free annular discs subjected to both pressure and assumed temperature distributions. Kurşun et al (2011) worked on the elastic stress analysis of power-law graded annular discs subjected to both uniform pressure on the inner surface and a linearly decreasing temperature distribution. Gönczi and Ecsedi (2015) studied analytically and numerically the thermo-mechanical behavior of a hollow power-law graded stress-free uniform circular disc under axisymmetric pressure and thermal loads.…”

In the present paper, thermomechanical attributes of a power-law graded uniform mounted disc with or without rigid casing are investigated analytically under centrifugal and steady-state thermal loads within the framework of axisymmetric infinitesimal plane-stress elasticity theory. Young's modulus, material density, thermal expansion coefficient and thermal conductivity are all assumed to be constantly changed in the radial direction with different inhomogeneity indexes while Poisson's ratio is kept constant. Two parametric studies are conducted by both hypothetically and physically chosen metal-ceramic pairs namely nickel-silicon nitride (Ni-Si3N4), aluminum-aluminum oxide (Al-Al2O3), and stainless steel-zirconium oxide (SUS304-ZrO2).

“…Thermal-related analyses of uniform disks made of anisotropic materials [11][12][13][14][15][16][17][18][19] and functionally graded materials [20][21][22][23][24][25][26][27][28] are other investigation themes. Unfortunately, the number of studies on the thermal/thermal related analysis of variable thickness disks made of either functionally graded (FG) materials [29][30][31][32][33][34][35][36][37][38][39][40][41][42] or traditional materials [43][44][45][46] are not enough.…”

Using the true temperature distribution along the radial coordinate, closed-form formulas are offered for readers to study the thermo-mechanical behavior of variable thickness disks having both convergent and divergent hyperbolic thickness profiles made of conventional materials. Internal and external pressures, centrifugal forces and thermal loads due to the differences in prescribed surface temperatures are all considered with three boundary conditions: free-free (a circular annulus), fixed-free (a disk mounted on a rotating shaft at the inner surface), and fixed-fixed (a disk mounted on a rotating shaft at the inner surface and cased at the outer surface) boundary conditions. A parametric study is also conducted in almost real working environment in which the outer surface of the disk has considerably higher temperature rather than the inner surface. The thermomechanical linear elastic response of a hyperbolic mounted rotating disk subjected to the external pressure induced by blades is originally handled by those proposed formulas.

“…Thermo-mechanical properties of functionally graded material (FGM) are assumed to be temperature independent and vary continuously in the radial direction of cylinder and the solution for the time-dependent temperature and thermomechanical stresses is obtained by employing Laplace transform techniques and series solving method for ordinary differential equation [3]. The elastic stress analysis of annular discs made of functionally graded materials subjected to both uniform pressures on the inner surface and a linearly decreasing temperature distribution was studied [4].…”
