Results from Cardamone et al. (2009), illustrating the effects of elastin prestretch distribution on the inverse axial retraction ratio λ = l/L, panel (a), and opening angle Φ0, panel (b), for the inner and outer sectors of a basilar artery; see figure 2 for more information. Here, parameter K represents different hypothesized prestretch distributions corresponding to varied sequences of elastin secretion and cross-linking during arterial development. These results demonstrate the potentially strong influence of constituent prestretches on measurable geometric quantities (reproduced from Cardamone et al., 2009).
