In the present article, theoretical analyses on heat conduction and thermally induced vibration problems are dealt with for homogeneous or nonhomogeneous elastic beams subjected to cyclic heat supply. Nonhomogeneous elastic solid model supposed in the present study has material properties given by the form of power function in term of transverse coordinate variable. We suppose the beam with simply supported edges is subjected to sinusoidal temperature fluctuation on one boundary surface and is insulted thermally on the other one. The effects of frequency in sinusoidal temperature fluctuation and nonhomogeneity in material properties on time evolutions and amplitudes in temperature change, vibration displacement and repeated thermal stress in beams are examined numerically.
