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.

Variational description of the positive column with two-stem ionization [PDF]
The ionization balance in diffusion dominated discharges which depends on both one and two step ionization processes is considered. The Spenke diffusion equation (D sq delta n + neutrino n + sq kn =0) describing such conditions is solved by the Rayleigh ...

Buckling of a sublaminate in a quasi-isotropic composite laminate [PDF]
The buckling of an elliptic delamination embedded near the surface of a thick quasi-isotropic laminate was predicted. The thickness of the delaminated ply group (the sublaminate) was assumed to be small compared to the total laminate thickness.

Development of a reduced basis technique for transient thermal analysis [PDF]
A technique to reduce the degrees of freedom in static and dynamic problems, the reduced basis method, is described. The method combines the classical Rayleigh-Ritz approximation with contemporary finite element methods to retain modeling versatility as ...

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

Similarities of discrete and continuous Sturm-Liouville problems
Electronic Journal of Differential Equations, 2007 In this paper we present a study on the analogous properties of discrete and continuous Sturm-Liouville problems arising in matrix analysis and differential equations, respectively.
