Abstract: An efficient analytical method is proposed so as to study the long-term performance of laminated tubes with neighboring layers glued by viscoelastic interlayers bearing inhomogeneous long-duration loads. In the analysis, the formulations for describing the mechanical performance of each tube layer are based on the elasticity theory, while the viscoelastic behavior of the glue interlayer is modeled by the generalized Maxwell model. Making use of the quasielastic approximation and the recursive matrix method, the analytical solution for the long-term performance of the laminated tube is solved efficiently. The present analytical solution is verified by comparing it with other solutions. The influences of the interlayer thickness, the material property, as well as the load distribution on the long-term performance of the laminated tube are discussed.
