Figure 8.

Engineering stress-stretch data for samples of brain tissue harvested from the occipital lobe in the frontal direction compared with the theoretical predictions. The material parameter values used to obtain the theoretical predictions from Equation (19) are summarized in Table 3, while the values of c = −0.0205 J/m³, m₁ = 0.006, r₁ = 2.5, r₂ = 1.8 and γ = 0.1 were used in Equation (26). The experimental data were adapted from [23].
