【Abstract】 Based on Reddy’s higher-order shear deformation plate theory, this paper investigates the bending of FGM rectangular plates subjected to uniform temperature change, initial inplane stresses and lateral loads. Material properties are assumed to be both temperature and position dependent. A semi-analytical approach is then developed for FGM plates with two opposite sides clamped and the others being either free, simply supported or clamped. Numerical results are presented for Si 3N 4/SUS304 plates, showing that the bending behavior of FGM plates are significantly influenced by material composition, temperature change, initial inplane loads, transverse shear deformation, and boundary conditions.$$$$更多还原
