О влиянии жесткости ребер на колебания и устойчивость незамкнутых цилиндрических оболочек
On numerical examples of analyzing the cylindrical shell, the effect of rib stiffness on the minimal natural frequencies and critical stresses are studied. The shell is assumed to be longitudinally compressed, non-closed and stiffened by the «quasi-regular» systems of longitudinal ribs. It is shown...

The shell is assumed to be longitudinally compressed, non-closed and stiffened by the «quasi-regular» systems of longitudinal ribs. It is shown that existence of the revealed before effect of sharp decreasing of minimal natural frequencies of vibrations don’t depend on the ribs stiffness in the case of fixed modes and small number of ribs. |
