Rayleigh Ritz Method Fem. The rayleigh ritz method uses global functions that are formulated over the entire domain of the structure. It is regarded as an ancestor of the widely used finite element method fem.
The rayleigh ritz method uses global functions that are formulated over the entire domain of the structure. It is used in mechanical engineering to approximate the eigenmodes of a physical system such as finding the resonant frequencies of a structure to guide appropriate damping. The name rayleigh ritz is a common misnomer used.
