Abstract:
In this article, a biomechanical model is presented for dynamic instability behavior of aorta arteries with atherosclerosis conveying pulsating blood including pharmaceutical nanoparticles. Utilizing Mindlin theory of cylindrical shell, the aorta artery is simulated mathematically. The atherosclerosis is assumed symmetric with lipid tissue. The pharmaceutical nanoparticles are subjected to magnetic field for attract to the lipid tissue in artery. Applying energy method and numerical method of differential quadrature (DQ), the final equations are solved for obtaining the dynamic instability region (DIR). The DIR is curve of dynamic blood velocity with respect to artery frequency. The influences of various variables of magnetic field, magnetic nanoparticle’s volume percent, tissue, lipid’s height and length upon dynamic behavior of aorta artery are investigated. Based on the results, the existence of magnetic nanoparticle in the blood enhances the artery frequency and consequently can lead to better heart performance and reduce the risk of heart attack.
