An Analysis of the Rayleigh--Ritz Method for Approximating Eigenspaces

, 1999
This paper concerns the Rayleigh--Ritz method for computing an approximation to an eigenspace X of a general matrix A from a subspace W that contains an approximation to X .

A study of the Numerical Convergence of Rayleigh-Ritz Method for the Free Vibrations of Cantilever Beam of Variable Cross-Section with Tip Mass

Engineering Transactions, 1996
A numerical study on the convergence properties of the Rayleigh-Ritz method is presented, for the dynamic analysis of beams with continuously varying cross-section. The beam is assumed to be slender, the Euler-Bernoulli hypotheses are accepted, and some

The Post-Buckling Behaviour of Thin-Walled Columns in the Elasto-Plastic Range

Engineering Transactions, 1986
The post-buckling behaviour in the elasto-plastic range of thin-walled, steel columns subject to uniform compression is analysed. The problem is solved using the Rayleigh-Ritz variational method involving plasticity.

The Rayleigh-Ritz method still competitive [PDF]

Journal of Computational and Applied Mathematics, 1994
An extended Rayleigh-Ritz method for computing two-sided eigenvalue bounds of the one-dimensional Schrödinger equation is presented. The method is based on the B-spline approximation over the truncated domain.
