Mechanics of Arterial Walls
Mechanics of Arterial WallsTo understand the mechanics of arterial walls, begin by imagining a long tube of constant cross section and constant wall thickness. This imaginary tube is homogeneous and isotropic (the material properties are identical in all directions). The typical blood vessel is branched and tapered. It is also nonhomogeneous and nonisotropic. Although our assumptions do not fit the blood vessel strictly speaking, it makes a practical first estimate of a model to help understand vessel mechanics. We need to continually remember our assumptions and the limitations they bring to the model as we progress in our knowledge of blood vessel mechanics.Consider a cross section of an artery as shown in
