Arteries are under significant mechanical loads from blood pressure, flow, tissue tethering, and body movement. It is critical that arteries remain patent and stable under these loads. This review summarizes the common forms of buckling that occur in blood vessels including cross-sectional collapse, longitudinal twist buckling, and bent buckling. The phenomena, model analyses, experimental measurements,...
According to deformation features of pre-twisted bar, its elastic bending and torsion buckling equation is deduced. The equation indicates that the bending buckling deformations in two main bending directions are coupled with each other, and bending and twist buckling deformations are also coupled with each other because the cross-section shear center does not coincide with the shape center. However,...
