Effect of linear and Mooney–Rivlin material model on carotid artery hemodynamics

Abstract Atherosclerosis is one of the most common cardiovascular diseases leading to high morbidity. The study arterial dynamics using fluid–structure interaction (FSI) technique by taking into account physiology flow, critical hemodynamic parameters can be determined which plays a crucial role in predictive medicine. Due advances computational facilities, coupled field analysis such as FSI facilitate understanding mechanics stenosis progression and its early diagnosis. In this two-way carried out modified Navier–Stokes equations governing blood flow for determining parameters. wall has been described at different linear elastic modulus compared with hyperelastic Mooney–Rivlin model evaluate effect stiffness on hemodynamics. predicts reduction severe backflow bifurcation resulting decreased shear stress oscillatory behavior. Furthermore, these findings may used advantages disadvantages artery numerical simulations better understand predict variable that causes diagnostic tool. present study, variation due change properties Mooney Rivlin influence hemodynamics are investigated.
