A Review of the Combination of Experimental Measurements and Fibril-Reinforced Modeling for Investigation of Articular Cartilage and Chondrocyte Response to Loading
Figure 2
Fibril orientation in the vector-based fibril reinforced models can be implemented with any given structure. The principle is that the fibril vector is given a direction at each point in the model (a). Two examples of the implemented structure are presented [16]. On the left, (b) an articular cartilage sample is modeled in unconfined compression geometry with a typical Benninghoff-type arcade structure including the superficial, middle, and deep layer. On the right, (c) a submodel of the global model presented on the left is implemented with pericellular matrix fibrils tangential to the cell surface. The extracellular matrix fibril vectors are not presented in (c) for clarity. The axis of symmetry has been indicated.
