Fig. 4.

Evolution of the nominal stress in collagen fibers and maximum principal Cauchy stress in the NCR and tissue matrix. The frames were captured at applied stretches corresponding to labels A-E in Figure 2. Top (a) and bottom (b) rows illustrate the evolving stress fields in the collagen fibers and non-collagenous matrix, respectively, during the entire uniaxial testing until just beyond the peak stress (λ=1.38), labeled E in Figure 2. Note: stress scale in first and second row are different.
