Abstract

A new approach, called "Variational Theory of Complex Rays", is applied to the calculation of slightly-damped, elastic structural vibrations of plates in the medium-frequency range. For each frequency of the studied frequency range, a small system of linear equations leads to the effective quantities (kinetic energy, vibrational intensity); in no way does this procedure require a detailed finite element discretization of the structure.
