INFLUENCE OF VARIOUS FACTORS ON THE VALUE OF CRITICAL FORCE
AND THE FREQUENCY OF FREE OSCILLATIONS OF POLYHEDRAL SHELLS

L.N. Kondrat'eva, I.B. Povarova

Abstract

In this paper, we present the results of analytical researches on the influence of various factors on the value of critical force and the frequency of free oscillations of thin shallow polyhedral shells made of flat plates. Here we show the dependency graphs of the free oscillation frequency on the shell aspect ratio and the number of fractures and give practical recommendations to the design engineers.

Keywords: thin shallow polyhedral shell; frequency of free oscillations; critical force.
