Abstract(in English) | An exact solution of a partial differential equation including elastic compliance constant S'_<56>, with respect to stress function Ψ has been found for torsional modes of vibration of an arbitrary (singly doubly triply) rotated beam with a pair of parallel, free edges. The solution is obtained by relaxing the condition that the edge planes are perpendicular to the main faces of the beam. That is, the edges are off perpendicular by the angle Θ=arctan((-S'_<56>)/(S'_<55>)). The exact solution can reduce the difference of the calculated and measured values for a thickness-to-width ratio where gives the first order temperature coefficient α=0. Also, a comparatively large-inclination of the edge cuts is required tb reduce the unwanted, complicated mode shapes to simple ones. |
