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.

STRUCTURAL TOPOLOGY REANALYSIS FOR TWICE CONTINUOUS MODIFICATIONS BASED ON COUPLED CONDENSATION

Jixie qiangdu, 2016
According to the problem of structural dynamical topological reanalysis for continuous two modifications,a new method for dynamic reanalysis of topological modified structure with added degrees and two continuous modifications was proposed in this paper ...
