From: Using In Vivo Cine and 3D Multi-Contrast MRI to Determine Human Atherosclerotic Carotid Artery Material Properties and Circumferential Shrinkage Rate and Their Impact on Stress/Strain Predictions J Biomech Eng. 2012;134(1):011008-011008-9. doi:10.1115/1.4005685 Stress-stretch plot of uniaxial test of a circumferential strip sample from a human carotid artery. The red curve is from the Mooney- Rivlin model fitting experimental data. The green straight line is from the linear model fitting the experimental data. Parameter values of the Mooney-Rivlin model and linear model fitting the experimental data are: c1 = 94.6 kPa, D1 = 6.81 kPa, c2 = 0, D2 = 2.0, YM = 570 kPa. Figure Legend:
