Responses of Cross-Ply Laminates with Viscous Interfaces in Cylindrical Bending

The responses of a simply supported cross-ply laminate in cylindrical bending with viscous interfaces are studied in this paper. Because of the introduction of viscous interfaces, the elastic fields in the laminate will depend on the time variable. The problem is solved exactly in the space domain, but approximately in the time domain. State-space method, which is very powerful for analyzing laminated structures, is employed. The variations of state variables with time are simulated using power series expansions. Numerical examples are considered and comparison with existent results validates the efficiency of the present method.
