THERMO-ELASTIC ANALYSIS OF A ROTATING HOLLOW CYLINDER MADE OF ARBITRARY FUNCTIONALLY GRADED MATERIALS

چکیده مقاله

Thermo-mechanical analysis of the functionally graded or- thotropic rotating hollow structures, subjected to thermo-mechanical load- ings is studied in this paper. The relations were derived for both plane strain and plane stress conditions as a cylinder and disk, respectively. Non homogeneity was considered arbitrary through thickness direction for all mechanical and thermal properties. The responses of the system including temperature distribution, radial displacement and radial and circumferential stresses were derived in the general state. As case study, power law gradation was assumed for functionally graded cylinder and the mentioned results were evaluated in terms of parameters of the system such as non-homogeneous index and angular velocity.
