Stress Analysis on Bioprosthetic Heart Valve Leaflets with Non-linear Material
The finite element software is often applied to stress analysis, which is also crucial to the design of anti-fatigue and anti-calcification of artificial heart valve. The material properties and the boundary conditions of bioprosthetic valve leaflets are defined and geometrical models are established. The linear material and the non-linear material of leaflets with different shapes are analyzed. After valve leaflets with the finite element models have been loaded, the finite element analysis results can be got.It is showed that the maximal primary stress of the valve leaflets with elliptic sphere is lower than that of the other valve leaflets and the stress distribution of the valve leaflet with elliptic sphere is comparatively reasonable. The work is helpful to make optimization design for the bioprosthetic heart valve and prolongs the lifetime of the synthetic heart valve.
