Theories and Analysis of Functionally Graded Beams

This is a review paper containing the governing equations and analytical solutions of classical shear deformation theories functionally graded straight beams. The classical, first-order, third-order account for through-thickness variation two-constituent material, modified couple stress (i.e., strain gradient), von Kármán nonlinearity. Analytical bending linear theories, some which are not readily available in literature, included to show influence material variation, boundary conditions, loads.
