The importance of the completeness of a set of solutions used in a direct variational method is herein discussed regarding a plate vibration application. The property is relevant to two issues: the claim of an “exact” ...

The effect of dead-time on the spectrum of pulsewidth modulated signals is analyzed in this paper. The study is valid for arbitrary, band-limited modulating signals, extending previous results in the literature. A simple ...

A variational method developed by the authors and named whole element method (WEM) is used to find the arbitrary precision frequencies of a rectangular thin plate (within the Germain}Lagrange theory) having its four borders ...

The study deals with the generalized solution of the title problem. The free vibration problem of a rectangular membrane with partial domains each of uniform density and arbitrary interface is tackled. Previous studies by ...

In the present study, a methodology to find natural frequencies with arbitrary precision of thin rectangular plates on linear intermediate supports and mixed boundary conditions is presented. This means that the edges are ...

In this paper, the plate is assumed as a regular prism of arbitrary aspect ratio and thickness with four consecutive faces clamped. By increasing the thickness from zero, one may model the thin, moderately thick and thick ...

A full computer-based methodology is proposed for electromagnetic transient simulations in power cables characterized by an arbitrary cross-section geometry. The frequency-dependent parameters of the cables are calculated ...
