THE INVESTIGATION OF STABILITY OF ELASTIC PLATES AND SHELLS WITH THE HELP OF FE MODELING

Abstract

The features of the finite element modeling and solution of problems of stability of elastic plates, closed spherical and spheroidal shells, shallow and nonshallow spherical shell segments in linear and geometrically nonlinear formulations, with the influence of small imperfections of the loading
