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.
