Rayleigh's power method

WebAs I understand The Rayleigh method is used for natural Frequency calculations (first mode only) in the command CALCULATE NATURAL FREQUENCY & also in the command DEFINE UBC LOAD or 1893 load. ... If the structure were free to vibrate, the modes of vibration will follow the ascending order of strain energy. Web10.1 Power Iteration In order to take advantage of the Rayleigh quotient approximation of the eigenvalue we need a good approximation of an eigenvector. We begin with the basic form of the power iteration algorithm. Algorithm (Power Iteration, simple form) Initialize v(0) with an arbitrary nonzero vector for k = 1,2,... v(k) = Av(k−1) end
