✦ Synopsis

A new approach, called the ''variational theory of complex rays'' has been developed in order to calculate the vibrations of slightly damped elastic plates in the medium-frequency range. The resolution of a small system of equations which does not result from a fine spatial discretization of the structure leads to the evaluation of effective quantities (deformation energy, vibration amplitude,. . .). Here, we extend this approach, which was already validated for assemblies of homogeneous substructures, to the case of heterogeneous substructures.

Modelling of the far-field energy distribution and power flow in point-loaded finite plates is considered. First, the two-dimensional conductivity equation governing the energy distribution in a plate is derived from fundamental energy and intensity considerations. The derivation, previously unrepor

Today, the main numerical modeling techniques for the analysis of medium-frequency vibrations are all based on finite element or boundary element approaches. In order to represent small-wavelength phenomena in complex structures such as car chassis, satellites or ships, these techniques require a hu
