Webdeveloping a higher order finite element. Zhou and Cheung [17] used Rayleigh-Ritz method by choosing a set of admissible functions and provided results for the natural frequencies of tapered beams with various boundary conditions. Later, they extended their work to cover tapered Timoshenko beams [18]. Webtechnique for accomplishing this is called the Rayleigh{Ritz procedure (it is also an example of the more general Galerkin technique). In its simplest form the technique retrieves an approximation to a simple eigenpair ( ;x)asfollows(herewedropthe iteration subscript). 1: Compute an orthonormal basis Wfor W. 2: Compute B= WHAW.
