Abstract In this paper, elastic-plastic stress analysis is done for a pressurized thick-walled functionally graded cylinder rotating along its axis with angular velocity so that the collapse of the cylinder under loading can be avoided. The problem is formulated for functionally graded transversely isotropic material by using Seth’s transition theory. Results are analysed theoretically and discussed numerically. From this analysis, it has been concluded that the cylinder made up of functionally graded transversely isotropic material (beryl) has less circumferential stresses than cylinder of transversely isotropic material (magnesium) and isotropic material (steel). Thus, transversely isotropic material (beryl) is safe as compared to the cylinder made up of transversely isotropic material (magnesium) and isotropic material (steel).
