| 中文摘要 | The nonlinear stress-strain relationship of synthetic fiber ropes under cyclic loading is a property of vital importance which directly influences the dynamic tension response of mooring lines. How to capture the load-elongation relationship of the synthetic fiber mooring lines under cyclic loading and obtain the quantitative description is a key problem which would be of interest to mooring system designers, platform operators and researchers. The former studies were insufficient to take into account the true loading history, creep behavior and the evolution of the dynamic stiffness. A viscoelastic and viscoplastic model is developed herein to describe the stress-strain properties of synthetic fiber mooring lines. The total strain is decomposed into a recoverable viscoelastic strain and an irrecoverable plastic strain. The time-dependent property and the evolution of the dynamic stiffness can be fully incorporated in the developed model. The model is examined by comparing with the experimental results of polyester ropes under both creep-recovery and sinusoidal loadings. Through a detailed parametric analysis, further knowledge of the hysteresis loop and the dynamic stiffness evolution is clearly obtained. The present work is beneficial to improving the understanding of the performance of synthetic fiber ropes, and also provides a better basis for the further research on the mechanical problems of synthetic fiber mooring lines under complicated loading conditions.
