Table 2.

11 best-fit parameters for each of the 10 specimens. The subscripts are $g$ for ground matrix, $c$ for collagen, $e$ for elastin, and $s$ for SMCs; The μ’s are the moduli and * indicates that it is the scaled variant, i.e., Eq. (14); b’s are the exponents where applicable, α denotes the orientation of the collagen fiber families around the longitudinal axis and θ is the overall orientation of the specimen in radians. $R^2$ is the coefficient of determination.
