CLAMPED CLAMPED NATURAL FREQUENCIES OF A BENDING TORSION COUPLED BEAM

An elegant and accurate method for determining the number of clamped-c lamped natural frequencies of a bending-torsion coupled beam which lie below a specified frequency is presented. The method facilitates an e asy and straightforward application of the Wittrick-Williams algorithm when finding natural frequencies of bending-torsion coupled beams, or structures which contain them. Numerical results are given for an ill ustrative example.;
