Ефект обтиску в задачах про коливання попередньо навантажених оболонок

Abstract

The paper presents a technique for studying the natural frequencies of nonthin inhomogeneous shells of revolution acted by static axisymmetrical loads. The technique is based on a nonclassic shell model that takes all the kinds of transverse deformation (transverse shears and reduction across a wall thickness) into account. The efficiency of allowing for the reduction across the wall thickness is illustrated by the example of a substantially inhomogeneous nonthin cylindrical shell with complicated structure.
