Description
Summary:By means of the finite element technique a study is carried out into the possibilities of thermal detuning of the modes of free transverse vibration associated with annular discs whilst subjected to heating at the outside peripheral radius. The detuning (or increasing the fundamental mode of vibration) is induced by the addition of heat at some intermediate radius of the disc. The changes in the natural frequencies are noted for varying degrees of intermediate heating at various intermediate radii.
