DYNAMIC LOSS OF STABILITY CLOSED CYLINDRICAL SHELLS AT ACTION OF BAND ALTERNATING LOADING

Abstract

In the given operation the question of dynamic loss of stability of closed cylindrical shells is researched. At influence on closed cylindrical shells of the cross alternating loading operating on a band, there are non-linear oscillations which result system in qualitatively new state. Researches were led on the basis of the analysis of change of sag of a shells in time, veyvlet-spectrum, change of the form of wave formation, and research of a sign on a high index of Lyapunov.
