Abstract

In the present study the free
vibration of Rayleigh beam composed of functionally graded materials (FGMs) is
investigated. For this purpose, the equation of the motion of functionally
graded (FG) beam derived according to Rayleigh beam theory. The material properties
are assumed to vary continuously through the thickness of the beam according to
the power-law form. Resulting equations are solved for simply supported
boundary conditions. In order to validate the results, a comparisons is carried
out with available results for homogeneous beam. The effects of varying
material properties on the dimensionless free vibration frequency parameters
are examined.
