Abstrakt
The aim of this contribution is to propose a new averaged model for stability
analysis of thin linear-elastic cylindrical shells having the periodic structure along
one direction tangent to the shell midsurface. In contrast with the known
homogenized models the proposed one makes it possible to describe the effect of
the periodicity cell size on the overall shell behavior ( a length-scale effect ). In
order to derive the goveming equations with constant or slowly varying
coefficients the known tolerance averaging procedurc is applied. The comparison
between the proposed model and the model without the length-scale effect is
presented.
