Abstract

Thermo-mechanical behavior of rotating functionally graded graphene reinforced composite (FG-GRC) circular disks with variable thickness and fixed-free boundary have been investigated. Two types of graphene nanoplatelet (GNP) dispersion patterns, i.e. the randomly oriented pattern and aligned one, are considered and the composite mechanical properties are predicted based on the Halpin–Tsai micromechanical model. By dispersing the disk into mathematical parts with non-uniform grids, governing equations are solved utilizing differential quadrature method. In numerical examples, influences of the material types, component contents, geometric shapes and temperature environment are discussed.
