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...
In order to improve long-term durability of bioprosthetic heart valve, stress distribution of bioprosthetic heart valve leaflets with different shapes under the same load is analyzed and compared based on finite element method. Combining traditional design theories and modern design methods, we create the cylindrical, spherical, paraboloidal and ellipsoidal curved surfaces in accordance with the geometrical...
