Static analysis of transversely or axially functionally graded tapered beams

Abstract

This paper presents the analytical solutions for the static analysis of the transversely or axially functionally graded beams with tapered cross-section. The elastic modulus of the beam varies continuously in the thickness or axial direction according to the power form. The closed form solution for the transversely functionally graded tapered beams is accomplished from the governing equation based on the Euler-Bernoulli beam theory and the principle of virtual work. The power series methodology is introduced to solve the governing equation for the axially functionally graded beam by transforming the governing equation into the series form. For comparison, the finite element model is utilised..
