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