FREE VIBRATIONS OF THE SPHERICAL SHELL CONTAINING AN ELASTIC FILLER

Blog Article

We study the free vibrations of a spherical shell filled with an elastic medium.The equa- tions of motion of a thin elastic spherical shell caruso milk thistle of exposure to internal pressure are given.Me- dium, filling the shell with a significantly has the lower modulus of elasticity.Solution for the free vibration of the system shell filler is presented.

We construct an ana- lytical solution of the problem, dependence of the oscillation frequency of the shell without the filler as a function of the frequency of the shell - filler.A plot of the frequency spectra for the footjoy weste herren two branches is given.
