Quasicomparison Functions and Substructure Synthesis for Framed Structures Stability Analysis
The Rayleigh-Ritz-Meirovitch substructure synthesis method (RRMSSM) is extended to buckling analysis in framed structures. The objective is a computational procedure capable of yielding very accurate critical loads through solution of very-low-order ...

On Rayleigh-Ritz Method in Three-Parameter Eigenvalue Problems
This paper deals with the computation of the eigenvalues of a three-parameter Sturm-Liouville problem in the form of ordinary differential equation using Rayleigh-Ritz Method, a method which is based on the principle of variational methods.

Optimal a priori error bounds for the Rayleigh-Ritz method [PDF]
We derive error bounds for the Rayleigh-Ritz method for the approximation to extremal eigenpairs of a symmetric matrix. The bounds are expressed in terms of the eigenvalues of the matrix and the angle between the subspace and the eigenvector.

On the application of the Rayleigh-Ritz method to a projected Hamiltonian [PDF]
We apply the well known Rayleigh-Ritz method (RRM) to the projection of a Hamiltonian operator chosen recently for the extension of the Rayleigh-Ritz variational principle to ensemble states.
