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.

The inverse Sturm-Liouville problem and the Rayleigh-Ritz method
, 1978 In this paper we present an algorithm for solving the inverse Sturm-Liouville problem with symmetric potential and Dirichlet boundary conditions. The algorithm is based on the Rayleigh-Ritz method for calculating the eigenvalues of a two point boundary ...

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.

Rayleigh-Ritz variational method with suitable asymptotic behaviour [PDF]
, 2019 This paper considers the Rayleigh-Ritz variational calculations with non-orthogonal basis sets that exhibit the correct asymptotic behaviour. This approach is illustrated by constructing suitable basis sets for one-dimensional models such as the two ...

, 1978 Estimates of flexural frequencies of clamped square plates are initially obtained by the modified Bolotin's method. The mode shapes in “each direction” are then determined and the product functions of these mode shapes are used as admissible functions in
