Viscous and elastic stress-strain relationships perpendicular to the collagen fibers were linear in form. Error bars are standard deviations. Mean viscous and elastic data were linearly regressed and fit with coefficients σV = 2.02 ε1 − 0.1732, R 2 = 0.97 and σE = 1.04 ε 1 − 0.097, R 2 = 0.99, respectively.
