From: Multiscale, Structure-Based Modeling for the Elastic Mechanical Behavior of Arterial Walls J Biomech Eng. 2007;129(4): doi: / Figure Legend: Schematic of the model. A multiscale model for the collagen network is combined with a single-scale (macroscopic) model of the noncollagenous material. The initial state of the artery is described by radius Ri, wall thickness H, and open angle Θ.
