Description
  • The terminating part of aorta - its branching into common iliac arteries is a part where atherosclerotic lesions occur very often. This may cause ischemic disease of lower limb and without treating may lead to amputation. The paper deals with this %22Y-shaped%22 part of aorta and describes it´s behaviour during physiological pressure loading. Both FEM model and physical (real) model were designed. The unique technological process for physical model casting and testing is described. Silicon elastomer Sylgard 184 was used for fabrication of the model. Pressure - location-specific deformation relationship was evaluated using FEM. One of results is that the stress concentration coefficient in the most dangerous place (%22crotch%22 of the bifurcation) may be more than 4.5 compared to nominal wall stress in the straight non-branched blood vessel. The second result is that the stress falls to the nominal value (the value in straight tube) approximately in the dista
