### Thermoelastic stresses in functionally graded rotating annular disks with variable thickness

functionally graded rotating annular disks with arbitrary thickness variations. The disk is

under pressure on its boundary surfaces and exposed to temperature distribution varying

linearly across thickness. Material properties are supposed to be graded in the radial di-

rection of the disk and obeying to two different forms of distribution of volume fraction of

constituents. Different conditions at boundaries for stresses and displacement are discus-

sed. Accurate and efficient solutions for displacement and stresses in rotating annular disks

are determined using infinitesimal theory. Numerical results are carried out and discussed

for different cases. It can be deduced that the gradient of material properties and thick-

ness variation as well as the change of temperature sources have a specific effect in modern

applications.
