A goal of the Human Research Program at National Aeronautics and Space Administration (NASA) is to analyze and mitigate the risk of occupant injury due to dynamic loads. Experimental tests of human subjects and biofidelic anthropomorphic test devices provide valuable kinematic and kinetic data related to injury risk exposure. However, these experiments are expensive and time consuming compared to...
This paper establishes parametric model of the bioprosthetic heart valve via computer aided design. Dynamic finite element analysis is used along with a geometrically accurate model of the bioprosthetic heart valve. The stress distribution of cylindrical and paraboloidal valve leaflets under the same load is analyzed as the leaflets are closed. The finite element analysis results show that the stress...
