Table 3.

Material parameters for the Rachev and Hayashi (1999) model determined via a nonlinear least squares regression with mechanical testing data collected from wild-type, mdx, and scgd−/− mouse carotid arteries under basal tone. Note that the best-fit parameters for the four-fiber family model (Table 2) were used to model the passive mechanical behavior. No significant differences were observed for Tact, λM, and λo across any groups.
