摘要：
In this paper, the displacement and stress fields in a functionally graded material (FGM) hollow circular disk, rotating with an angular acceleration under a changing temperature field, are achieved by using a semi-analytical approach. The material properties are assumed to vary along the radial coordinate and related to the volume fraction of each material. The modulus of elasticity and the coefficient of thermal expansion are supposed to be temperature-dependent, while the Poisson's ratio is assumed to be constant. In numerical examples, effects of the functionally graded index, the geometric shape, the angular speed and the temperature boundary conditions to the displacement and stresses are considered. The results of this study may be useful for other investigations of rotating FGM circular disks with variable thickness. (C) 2016 Elsevier Inc. All rights reserved.
