Abstract:
Objective To study the material attribute of articular cartilage.Methods An improved 4 parameters inhomogeneous triphasic model based on 3 parameters model was developed to estimate the uniaxial modulus Ha of cartilage and to predict the swelling pattern of cartilage.Results The results showed that more accurate uniaxial modulus can be extracted using 4 parameters inhomogeneous triphasic model,and the predicted results appeared to match the experimental strain data better than other models.Conclusion Inhomogeneous 4 parameters triphasic model can describe the depth-dependent material attribute of articular cartilage more exactly.
