Figure 6:

Multigenerational growth of fibers with damage, as described in Example 6. (a) Cauchy stress versus strain during loading and unloading, and (b) damage $D$ versus time. All fibers exhibit the same damage response, however individual fiber damage have different reference configurations due to multigenerational growth, implying that the maximum normal stress in each bundle is different. The hyesteresis loop in the stress-strain response reflects the energy dissipated due to damage.
