Özet

This paper presents a finite element model based on the first-order shear deformation theory for free vibration and budding of functionally graded beams. The present element has five nodes and ten degrees of -freedom. Material properties vary continuously through the beam thickness according to the power-law form. Governing equations are derived with the aid of Lagrange's equations. Natural frequencies and buckling loads are calculated numerically for different end conditions, power-law indices, and span-to depth ratios. Accuracy of the present element is demonstrated by comparisons with the available results. (C) 2016 Elsevier Ltd. All rights reserved.
