| Abstract: | Based on an inextensional two-parameter analytical model for laminated cylindrical shells,the relationships between the bistable properties of laminated shells with graded fibers and the distribution patterns and Young's moduli of the fibers are studied in this paper.The fibers are distributed through-thickness in power law from the middle surface to top and bottom surfaces.The distribution regulation of the constituent volume fraction has been obtained for the availability of the second stable equilibrium ... |
