Abstract: Procedure of calculation of critical buckling time of shells under creep with use of Rabotnov's variation equation is presented. Comparison of critical times for the reinforced shells is calculated with use of three-layer model with experimental data and results obtained by other authors is also presented.

Keywords: critical buckling time, two-layer shell model, reinforced shells, creep.
