| dc.description.abstract | Articular cartilage and ligament are soft fibrous connective tissues with apparent viscoelastic behavior. An anisotropic visco-hyperelastic constitutive model for these tissues has been proposed in this study based on the short-term and long-term internal variables. The constitutive model was particularized for both tissues, numerically implemented into the finite element software package ABAQUS and the material parameters were identified using the available experimental data. The constitutive model was able to capture both the short-term and long-term time-dependent response of these tissues with less difficulty in material characterization process. Due to the lack of the desired tensile experimental results on articular cartilage, the mechanical behavior of this tissue was also examined experimentally. The tensile stiffness of articular cartilage was found to be rate-dependent. It has been shown by numerical simulations that the strain-rate dependent tensile stiffness of collagen fibers can also contribute to the highly rate-dependent compressive response of articular cartilage, besides the fluid-driven viscoelasticity. | en_US |
