Это напряжение состоит из двух слагаемых, отражающих способность оболочки сопротивляться выпучиванию за счет изгибных и мембранных деформаций. При ненулевом коэффициенте Пуассона развивается осесимметричный краевой эффект, который уменьшает критическую нагрузку и приводит к изменению начального расположения собственных форм по мере роста нагрузки (конкуренция собственных форм). Установлено, что в условиях краевого эффекта оболочка всегда теряет устойчивость по только неосесимметричным формам. Показано, что если краевой эффект не развивается, то порядок собственных форм потери устойчивости при нулевой нагрузке и при нагрузке близкой к критической идентичен, то есть явление конкуренции собственных форм не возникает.</p></abstract><trans-abstract xml:lang="en"><p>The paper deals with the features of the classic solution for critical stresses in the stability problem of a longitudinally compressed circular cylindrical shell. This stress consists of two terms, reflecting the ability of the shell to resist buckling due to bending and membrane deformations. With a non-zero Poisson's ratio, an axisymmetric edge effect develops, which reduces the critical load and leads to a change in the initial order of the eigen modes as the load increases (competition of eigen modes). It is established that shell with the edge effect always loses its stability only in non-axisymmetric forms. It is shown that if the edge effect does not develop, then the order of eigen forms at zero load and at a load close to critical is identical, that is, the phenomenon of competition of eigen formes does not arise.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цилиндрическая оболочка</kwd><kwd>устойчивость</kwd><kwd>краевой эффект</kwd><kwd>напряжение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cylindrical shell</kwd><kwd>stability</kwd><kwd>edge effect</kwd><kwd>stress</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Вольмир, А.С.
