Notes

Abstract: This work focuses on the experimental characterization of suture material samples of MonoPlus, Monosyn, polyglycolic acid,
polydioxanone 2–0, polydioxanone 4–0, poly(glycolide-co-epsilon-caprolactone), nylon, and polypropylene when subjected to
cyclic loading and unloading conditions. It is found that all tested suture materials exhibit stress-softening and residual strain effects
related to the microstructural material damage upon deformation from the natural, undistorted state of the virgin suture material.
To predict experimental observations, a new constitutive material model that takes into account stress-softening and residual strain
effects is developed.Thebasis of thismodel is the inclusion of a phenomenological nonmonotonous softening function that depends
on the strain intensity between loading and unloading cycles. The theory is illustrated by modifying the non-Gaussian averagestretch,
full-network model to capture stress-softening and residual strains by using pseudoelasticity concepts. It is shown that
results obtained from theoretical simulations compare well with suture material experimental data.
