Figure 5: Constitutive model parameter affecting mechanical behavior at high-stretch is increased in response to irradiation.

Average constitutive model parameters, c (kPa) and k (−), estimated for tissue from irradiated animals (filled bars) and for untreated animals (empty bars) collected 3-months (A) and 6-months (B) post-treatment. Error bars represent standard error mean. Two-way ANOVA was performed followed by Bonferroni’s post-hoc test correcting for multiple comparisons. **P < 0.01 when comparing untreated and irradiated animals at each time point.
