| Abstract: | The analytical study deals with stress analysis
of functionally graded rotating annular discs subjected to internal pressure
and various temperature distributions, such as uniform T0 (reference temperature), linearly increasing Tb (outer surface temperature)
and decreasing Ta (inner
surface temperature) in radial direction. Infinitesimal deformation theory of
elasticity and for graded parameters power law functions are used in the
solution procedure. The results show that the tangential stresses increase at
the inner surface and decrease at the outer surface with increasing T0 and Tb temperatures. If Ta
is increased, they decrease at the inner surface and rise at the outer surface.
The radial stresses reduce gradually along the radial section with increasing T0 and Ta temperatures, whereas they rise along the radial
section when Tb is
increased. The radial displacement values in the discs subjected to uniform
temperature T0 are higher
compared to the discs subjected to other kind of temperature distributions. The
radial displacement has higher value at the outer surface than that of the
inner surface for all the temperature distributions, except for radial
displacement in the reference temperature case. The stresses and displacement
values in a disc under uniform temperature are compared with the values given
in the literature and they are found to be consistent with each other. |
