THE EFFECT OF THERMAL LOAND ON THE NATURAL FREQUENCIES OF DOUBLE-CLAMPED BEAMS
The natural frequencies of double-clamped beams are influenced by environmental conditions and operational loads. For instance the temperature induces axial loads due to restraint displacements, which lead after a critical temperature increase to buckling. This paper clarifies the effect of external loads on the natural frequencies of beams.
