Effect of material inhomogeneity on the rotating functionally of a graded orthotropic hollow cylinder

Abstract

The effect of the material inhomogeneity on the stress field of a rotating orthotropic infinite hollow cylinder made of functionally graded materials is investigated. The original functionally graded hollow cylinder is approximated by the laminate model, of which the solution will gradually approach the exact one with the increase in number of fictitious layers. The analysis is performed by means of the state space method. The validity of the solution is verified by utilizing the exact solution of a special non-homogeneous rotating hollow cylinder and earlier results. The distributions of the radial and tangential stresses of the internally pressurized rotating functionally graded hollow cylinder for various material inhomogeneity parameters are depicted graphically. The degree of the orthotropy on the stress fields is also discussed.

“…Rotating disks and cylinders have important applications in rotating machinery and structures, such as flywheels, steam and gas turbines, high-speed cameras, planetary landings, aviation, rocketry, missiles, chemical, aerospace, mechanical, and nuclear industries (Malekzadeh et al, 2012;Wang, 2010). The stress analysis of the rotating homogeneous isotropic, orthotropic, and anisotropic disks and cylinders is an important topic in the engineering design and applications (Galic and Horgan, 2003).…”
