Pełzanie cienkich obrotowo-symetrycznych powłok na podstawie teorii ustalonego płynięcia

The paper presents an exact solution of the stability problem of the creep in the range of large deformations of thin axially-symmetric shells based on the theory of steady-stale plastic flow. On the basis of eqs. (2.3) and (2.4), the analysis of stress distribution and deformations along the meridian of the shell are given and also the so-called ,,critical times'' of the creep for the shells considered are obtained.
