Abstract

This study is concerned with theoretical development for thermal induced vibration problem of beam. We suppose that thermal and mechanical material properties in beam are given as power function in term of transverse coordinate z. Firstly, we have developed two-dimensional transient heat conduction problem of homogeneous beam due to cyclic heat supply. Then, we have developed thermal induced vibration problem of beam clamped at one edge and free at opposite edge. Next, we have carried out numerical calculations and have discussed about effect of cyclic temperature fluctuation on thermal displacements, thermal stresses and resonance characteristics in beam.
