By allowing for frequency variation in the virtual displacement/co-ordinates, a generalized Galerkin's procedure is developed. This leads to a compact form of Galerkin's conditions, which in turn yield as many algebraic equations as the number of unknown parameters and frequency(ies). The independen

The generalized equal width (GEW) equation is solved numerically by the Petrov-Galerkin method using a linear hat function as the test function and a quadratic B-spline function as the trial function. Product approximation has been used in this method. A linear stability analysis of the scheme shows
The objective of this paper is to consider the dynamic motions of second order, weakly non-linear, discrete systems. The main attention is focused on a comparison, for such systems, of the method of Krylov-Bogoliubov (KB) and an enhanced Galerkin (EG) method which produce seemingly different solutio
