Webis called a Rayleigh quotient. Remark If x is an eigenvector of A, then Ax = λx and r(x) = λxTx xTx = λ. In general one can show that λ min ≤r(x) ≤λ max. Another fact about the Rayleigh … WebRayleigh's method requires an assumed displacement function. The method thus reduces the dynamic system to a single-degree-of-freedom system. Furthermore, the assumed displacement function introduces additional constraints which increase the stiffness of the system. Thus, Rayleigh's method yields an upper limit of the true fundamental frequency.
