| 英文摘要 | The temporal response of collagen fiber can be characterized by the shortand long-term behaviors. The short-term behavior can be described by the strain rate sensitivities, whereas the long-term behavior can be demonstrated by the creep and stress relaxation. The relative performance of a number of alternative methods to model the viscoelastic behavior of collagen fibers during constant strain rate loading is investigated, the results show that in order to simulate the toe region of the nonlinear stress-strain curve of soft tissues, the Quasi-linear viscoelasic (QLV) theory, nonlinear Bailey Norton law, and the Zener model can be used. However, the successful simulation for both the toe and yielding region can only be achieved by utilizing the nonlinear Bailey Norton law and Zener model. The result of least squared fit between experimental and numerical simulations indicated that the Zener model provides the best simulations of viscoelastic behavior of soft tissues such as collagen fibers. The incorporation of Zener model in multi-body biomechanical models can contribute to the realistic simulation of complex joint mechanics. |
