Abstract


This paper deals with the thermo elastic analysis of a FG cylinder with different boundary conditions under internal pressure using the first order shear deformation theory. This proposed solution has the ability to solve the cylinder structure with arbitrary boundary conditions. The previous studies have been proposed for the problem with simple boundary conditions (simply supported cylinder). This paper investigates the axial distribution of the displacement and stress for different values of non-homogenous index. This investigation indicates that a support has important influence on the distribution of mechanical components rather than a cylinder with ignoring the effect of support.  Simultaneously effect of the temperature and pressure are studied on the deformation and stress of cylinder. Calculation of the stress concentration factor due to end effects is another result of the present paper. The presented results are validated by comparison with previous results that have been evaluated using the plane elasticity theory.
