Transverse Shear and Rotary Inertia Effects on the Stability Analysis of Functionally Graded Shells under Combined Static and Periodic Axial Loadings F. Ebrahimi*, H. Sepiani
The Journal of Mechanical Science and Technology, vol. 24, no. 12, pp.2359-2366, 2010
Abstract : The effect of transverse shear and rotary inertias on the dynamic stability of functionally graded cylindrical shells subjected to combined
static and periodic axial forces is investigated in this paper. Material properties of functionally graded cylindrical shells are considered
temperature-dependent and are graded in the thickness direction according to a power-law distribution in terms of the volume fractions
of the constituents. Numerical results for silicon nitride-nickel cylindrical shells are presented based on two different methods: the
first-order shear deformation theory (FSDT) which considers the transverse shear strains and the rotary inertias, and the classical shell
theory (CST). The results obtained show that the effect of transverse shear and rotary inertias on the dynamic stability of functionally
graded cylindrical shells subjected to combined static and periodic axial forces is dependent on the shell¡¯s material composition, environmental
temperature, amplitude of static load, deformation mode, and the shell¡¯s geometry parameters.
