Rayleigh-ritz method for natural frequency
WebExploiting a special code written on MATLAB®, the flexural natural frequencies of the plate are found by sweeping the frequency domain in search of specific frequencies that yield a zero determinant. ... The Rayleigh-Ritz method is another very popular exact method that has been exploited by many researchers in the past. WebThe arbitrary parameters are determined by minimizing the natural frequency by the rules of differential calculus or by a number of trial calculations, in difficult problems. Although the …
