Investigation of the elements of the printing device

Abstract

The finite element of a composite beam is constructed from the lower and upper sub-elements of the beam type and an internal sub-element of an elastic layer type. It is shown that the multiple eigenmodes exist in a circular system. They are suitable for the excitation of wave motion in it. The quantity proportional to the one obtained in the photoelastic investigations is calculated numerically and represented by the intensity mapping. The obtained results provide the basis for the investigation of devices incorporating the layer of the fluid when viscosity is important.
