Abstract

Abstract The paper present the free vibration and the flutter of multi-layered cylindrical shells using the Rayleigh-Ritz method. The optimal design with constraints imposed on the eigenfrequencies is particularly useful in the selection of dynamic characteristics of structures. For composite cylindrical shells, the fiber orientation variations in individual layers results in an increase (decrease) the critical value of free vibrations. Optimal fibre orientations depends on the shell support and on the geometric parameters of a structure. In the case of the optimal laminate configuration finding, the optimization task cannot be solved using standard FEM software the application and genetic algorithms are required.
