Simulation of discontinuous damage incorporating residual stresses in circumferentially overstretched atherosclerotic arteries

D Balzani, J Schröder, D Gross - Acta biomaterialia, 2006 - Elsevier
When a balloon-angioplasty is performed, the arterial wall is overstretched and thereby
damaged, which leads to a stiffness reduction in the arterial layers. An anisotropic damage …
