Adaptive Remodeling of Achilles Tendon: A Multi-scale Computational Model
Fig 3
Normalized fatigue curve for whole tendon.
The fatigue curve is constructed by rescaling the empirical data from [38] so the ultimate tensile strength equals the in vivo failure stress reported for young adults, 100 MPa [64–66]. Cumulative damage to collagen fibers is based on fitting a commonly adopted exponential failure function to typical fatigue test data on human Achilles tendon.
