Fig. 6.

von Mises stress and green strain distributions of the area-preserved valves at the end of diastole in different deformation configurations (top and 45 deg tilted views). To help visualize regions of highest stresses and strains, both top and 45 deg tilted views are illustrated. To facilitate comparisons, the fringe levels were set to the same range for all the stress and strain distributions. All regions having stress values above the maximum value of the fringe are shown in black. Sagging and stretching of leaflets are also observed in the elliptical and D-Shape configurations.
