Abstract

The main purpose of this paper is to validate the spring-based fibiril-reinforced porous elastic model of articular cartilage. In this study, the ability to interpret the process of axial reaction and lateral displacement in unconfined compression experiments was used as a criterion to prove the correctness of the model. The parameters of mechanical properties are obtained by means of parameter inversion, and the model is tested based on these parameters. The simulation results and experimental data were compared and obtained: The fibiril-reinforced porous elastic model based on spring can't reflect the stress distribution in the unconfined compression experiment and can't explain the relaxation process of the axial reaction force. This is because the fiber distribution of this model does not match the actual situation, not taking into account the articular cartilage itself inherent viscoelasticity.
