摘要：
In this paper, we use the semi-inverse method to find the solutions to the dynamic equation of inhomogeneous, functionally graded simply supported beams. For the anti-symmetric mode and the material density (or the Young's modulus) that are both polynomial functions and and have been prespecified, we find the Young's modulus (or the density) in polynomial functions and determine the closed from expression for the natural frequency.
