Abstract

An analytical transition relation between the natural frequencies of functionally graded material (FGM) beam based on the Levinson beam theory and that of the reference homogenous Euler-Bernoulli (E-B) beam is presented under simply supported boundary conditions. Material properties of the FGM beam are assumed to be varied continuously in the beam depth. By examining the mathematical similarity between the governing equations with boundary conditions of the two types of the beams for free vibrations, natural frequency of the FGM Levinson beam is expressed analytically in terms of that of the reference homogenous E-B beam. Consequently, solving the complex coupling differential equations with boundary conditions, or searching for the natural frequency of the FGM Levinson beam is simplified as the calculation of a serious of coefficients which can be easily determined by a specified gradient of the material properties and the geometry of the FGM beam. As a result, homogenized and classical expression for the response of free vibration of simply supported FGM Levinson beams is realized, which can provide a good convenience for engineering applications.
