Illustration of the methodology used to determine model parameters. Top row, left to right: specimen of carotid artery between the clamps of the UA-MPM device, illustration of collagen recruitment analysis, depiction of collagen orientation analysis. Middle row, left to right: raw stress-stretch results from testing, tortuosity data and the Gamma cumulative distribution function plotted against stretch, orientation distribution histogram. Bottom: final results from UA-MPM testing of a rabbit carotid artery. Raw stress-stretch data (blue dots) and structural model fit (blue line) from uniaxial tension tests in the circumferential direction with overlaid recruitment probability distribution function (green line).
