  • Title: Wall stress and deformation analysis in a numerical model of pulse wave propagation.
    Author: He F, Hua L, Gao L.
    Journal: Biomed Mater Eng; 2015; 26 Suppl 1():S527-32. PubMed ID: 26406044.
    Abstract:
    To simulate pulse wave propagation, we set up a wave propagation model using blood-wall interaction in previous work. In this paper, our purpose is to investigate wall stress and deformation of the wave propagation model. The finite element method is employed for solving the governing equations of blood and wall. Our results suggest that there are two peaks in the circumferential stress and strain distributions of the normal model. The stress and strain values change with the varieties of different factors, such as wall thickness and vessel diameter. The results indicate that different parameters of fluid and tube wall have remarked impact on wall stress and deformation.
