Rayleigh quotient method python

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. WebThe Rayleigh–Ritz method is a direct numerical method of approximating eigenvalues, originated in the context of solving physical boundary value problems and named after …
