Fibril-reinforced poroviscoelastic model is employed to replicate experimental strain results from biomechanical testing. Model concordance to the experimental strain is achieved by optimizing model parameters that mirror real constituents of articular cartilage: initial and strain-dependent fibril network modulus (E_f⁰, E_f^ε, respectively), nonfibrillar matrix modulus (E_nf), initial permeability (k₀) and strain-dependency of permeability (M).
