A schematic of the final fully connected NN model for planar mechanical behavior of native and replacement heart valve leaflet soft tissues. The input nodes consist of the strain tensor components and the Γ standard deviation. The output is the three stress tensor components. Note that the shear stress term is post-multiplied with the shear strain, resulting in that zero shear strain gives zero shear stress as fitting constraint (see text for details).
