Bending and Deformation of Sandwich Panels Due to Localized Pressure
ITB Journal of Engineering Science, 2005 Bending and deformation of sandwich panels due to localized pressure were analyzed using both Rayleigh-Ritz and finite element methods. The faces were made of laminated composite plates, while the core was a honeycomb material.

Quasicomparison Functions and Substructure Synthesis for Framed Structures Stability Analysis
Latin American Journal of Solids and StructuresThe 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 ...

Stabilizing the Rayleigh--Ritz procedure by randomization
CoRRExtracting approximate eigenpairs from a prescribed subspace is of fundamental importance in eigenvalue computation. While projecting the target eigenvector onto the subspace yields satisfactory accuracy, extracting an approximate eigenpair that attains a comparable convergence rate has remained a long-standing open problem.

A generalization of Saad's theorem on Rayleigh–Ritz approximations
Linear Algebra and its Applications, 2001 If \(A\) is a Hermitian matrix with eigenpair \((\lambda,x)\) and Ritz pair \((\mu,u)\) from the subspace \({\mathcal K}\), then \textit{Y. Saad} [Numerical methods for large eigenvalue problems: Theory and algorithm, Wiley, NY (1992; Zbl 0991.65039)] gives an estimate of the form \(\sin \angle (x,u)\leq C \sin\angle(x,{\mathcal K})\), with \(C ...

Eigenfunction Convergence of the Rayleigh-Ritz-Meirovitch Method and the FEM
Shock and Vibration, 2007 Eigenfunction convergence characteristics of the finite element method and the Rayleigh-Ritz method with quasicomparison functions (RRMM) are compared. The RRMM has previously proved to be superior in comparing eigenvalue convergence characteristics. The
