On dynamics and stability of thin periodic cylindrical shells

International Journal of Differential Equations, 2006, vol. 2006, 1-23

Abstract:

The object of considerations is a thin linear-elastic cylindrical shell having a periodic structure along one direction tangent to the shell midsurface. The aim of this paper is to propose a new averaged nonasymptotic model of such shells, which makes it possible to investigate free and forced vibrations, parametric vibrations, and dynamical stability of the shells under consideration. As a tool of modeling we will apply the tolerance averaging technique . The resulting equations have constant coefficients in the periodicity direction. Moreover, in contrast with models obtained by the known asymptotic homogenization technique , the proposed one makes it possible to describe the effect of the period length on the overall shell behavior, called a length-scale effect .
