Stress vs. stretch for each of our three constitutive models alongside the experimental data of [41], showing that the fibrous model best captures the material behavior, followed by the Blatz model. Material parameters are as follows for each model: Fiber-based, λ = 3.79KPa, μ = 2.53KPa, κ = 3.61KPa, γ = 9.23; Blatz, λ = 21.97KPa, μ = 5.49KPa, γ = 11.92; Neo-Hookean, λ = 79.83KPa, μ = 19.96KPa.
