Abstract
The present paper develops application of third-order shear deformation theory (TSDT) and modified couple stress
theory (MCST) to size-dependent bending analysis of a functionally graded cylindrical micro-shell. The radial and axial
displacement components are described based on TSDT for more accurate analysis. The effect of small scales is accounted
based on MCST. The principle of virtual work is used for derivation of bending governing equations. The solution is presented
for a simply-supported boundary condition to account the influence of various important parameters such as micro length scale
parameter, in-homogeneous index and some dimensionless geometric parameters such as length to radius and length to thickness
ratios on the bending results. A comparative analysis is presented to examine the effect of order of employed shear deformation
theory on the axial and radial displacements.
