Stress-sharing between the fluid and solid components of articular cartilage under varying rates of compression.
This paper investigates the factors affecting the mechanical behavior of the articular cartilage matrix with special emphasis on the effect of compressive strain-rate on the short and long term responses of the fluid and the solid components. The relationships expressed in the general theory of one-dimensional consolidation are generalized to account for strain-rate in the deformation process with the result that the stiffness due to the fluid and the solid components, and a parameter representing the degree of drag, can be calculated explicitly.
