Table 1.

Best-fit values of the material parameters used to fit the biaxial mechanical data and thus to compute biaxial stress, material stiffness, and stored energy for the Ltbp3^−/− and Fbn1^mgR/mgR:Ltbp3^−/− vessels. Values of the parameters for WT, Fbn1^mgR/mgR, and aneurysmal Fbn1^mgR/mgR (TAA) aortas are reproduced from (Bellini et al. 2016) for convenience.
