The deformations and the internal forces at a cross section of a beam are taken as state variables to formulate a general equation for computing the natural frequencies of non-uniform beams.

The results show that there exists the tension-bend coupling deformation in the uniformly heated beam because of the non-uniform characteristic of materials.
