the effect of magnetic nanoparticles on dynamic behavior of aorta artery with atherosclerosis under the action of pulsating blood velocity

In this article, a biomechanical model is presented for dynamicinstability behavior of aorta arteries with atherosclerosis conveyingpulsating blood including pharmaceutical nanoparticles. utilizingmindlin theory of cylindrical shell, the aorta artery is simulatedmathematically. the atherosclerosis is assumed symmetric withlipid tissue. the pharmaceutical nanoparticles are subjected tomagnetic field for attract to the lipid tissue in artery. applyingenergy method and numerical method of differential quadrature(dq), the final equations are solved for obtaining the dynamicinstability region (dir). the dir is curve of dynamic bloodvelocity with respect to artery frequency. the influences of variousvariables of magnetic field, magnetic nanoparticle’s volumepercent, tissue, lipid’s height and length upon dynamic behavior ofaorta artery are investigated. based on the results, the existence ofmagnetic nanoparticle in the blood enhances the artery frequencyand consequently can lead to better heart performance and reducethe risk of heart attack.
