✦ Synopsis

The present paper deals with the analysis of certain dynamic aspects of the blhaviour of beams and plates which support elastically mounted masses.

Shear and rotatory inertia effects are not taken into account in the present investigation. An exact solution is presented in the case of a simply supported beam.

This solution can be easily extended to the problem of a simply supported rectangular plate.

It is also shown that use of a variational formulation leads to accurate and simple expressions for natural frequencies and dynamic displacements and stresses which are ideal from a designer's viewpoint. The case of supports elastically restrained against rotation is also considered.

The experimental phase of the investigation shon;ed good agreement with experimental results.
