A fluid?structure interaction study on the biomechanical behaviour of a curved artery with flexible wall

Research has shown that thrombus, stenosis, aneurysm, atherosclerosis and other vascular diseases are likely to occur in curved arteries such as aortic arch, coronary artery and cerebral artery. It is found that fatigue damage and failure of arteries are closely associated with the dynamic physiological environment where the arteries are situated. Based on these considerations, the behaviour of curved arteries subjected to a physiological environment is presented in this paper. The fluid-structure interaction (FSI) effect is considered. Wall stress distribution and its variation over time are investigated. Artery deformation regularity throughout the cardiac cycle has been analysed. It is believed that this study may provide insights into clinical research in the future.
