Vibration of a rectangular plate with a central power-law profiled groove by the Rayleigh-Ritz method by Daniel O'Boy, Victor V. Krylov

“…The prediction of natural frequencies of rectangular plates where a profiled indentation is present is made using a Rayleigh-Ritz variational energy method. Panels with holes are often found for access cables and access gaps, and it is shown that the application of damping to the profile leads to a more efficient method of reducing vibration than covering a whole rectangular plate, which is advantageous where weight saving is necessary.…”

Water-wave propagation through very large floating structures by Benjamin Carter

“…We then solve the same infinite array problem using a numerical approach, namely the Rayleigh-Ritz method, for fixed cylinders in water of finite depth and deep water. …”

Spectral analysis: theory and numerical results by Robert Marlow

“…This paper explains how spectral theory characterises an operator, acting on a Banach or Hilbert space, and so helps to solve an equation of that operator, or characterise its solution. Sobolev spaces are discussed, and then Spectral theory is applied to a Laplace operator with Dirichlet boundary conditions, and the eigenvalues characterised. …”

Self-twisting blades for passive regulation of a small wind-turbine by Julian Feuchtwang

“…There is a need to optimise the blade design to exploit this effect to the full. The equations describing the blade twist are developed and expresseds imply and explicitly in terms of blade shaped esignp arameters. …”
