The weekly Wednesday seminar on 12 November 2014, 10.00 a.m., will feature Professor Jafar Gasanaga ogly Agalarov (Head of Department of Wave dynamics, IMM) who will talk about “Free oscillation of spherical shell filled with elastic fluid”.

Consider a thin elastic spherical shell. The shell is filled with an elastic medium with a lower elasticity. The equations of motion are made in spherical coordinates and, using the contact conditions of the dynamic equations are written. The equations of motion are written without filler. The equations of the elements considered for hesitation. For the existence of solutions are written conditions. Comparing these conditions for shell and the shell of the oscillation frequency with the frequency of oscillation of the system. Results are graphically illustrated in the example and illustrated in the form of two branches of the frequency spectrum.
