چکیده مقاله:

an abnormal narrowing of a blood vessel stenosis is investigated in this study the present work provides a simulation of blood in a vessel with 50%stenosis in addition the effects of tissue surrounding the blood vessel on displacements and stresses in stenotic vessel wall are considered the analysis consists of two distinct but coupled procedures: first,a fluid-dynamics analysis including a calculation of the velocity field and pressure distribution in the blood variable in time and in space: second ,a mechanical analysis of the deformation of the tissue and vessel to do so COMSOL multiphysics as a powerful software was used to simulate the wall-blood interaction the diameter of vessel is 8millimeters and the blood assumed to be a newtonian and incompressible fluid in addition to the walls of vessel and surrounding biological tissue were assumed to be a hyper -elastic material .
