THE VARIENT OF RAYLEIGH'S METHOD APPLIED TO TIMOSHENKO BEAMS ON WINKLER-PASTERNAK FOUNDATIONS. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3
The determination of the fundamental frequencies of timoshenko beams in a Winkler-Pasternak medium is presented. It is proposed the use of the variant of Rayleigh's method which allows an optimization of the approximate modal functions through a non-integer exponential parameter. The case under study gives rise to a two-variable problem. Numerical results are given for hinged-hinged and clamped-clamped beams of uniform and variable cross section. Comparisons with available exact values yield very good agreement. (Author/TRRL)
