(a): Simulated equi-biaxial stress vs. strain curves in the fiber (solid lines) and cross-fiber (dashed lines) directions for case 2. Each set of curves represents the material properties assessed before unloading (in blue), after first unloading (in red), after second unloading (in green), and after third unloading (in cyan).

(b): Average of the five cases, showing the fiber (solid curves) and cross-fiber (dashed curved) stress vs. strain from the simulated equi-biaxial extension, before unloading (in blue), after final unloading (in green) and results of reference [12] (average of four cases) from excised unloaded porcine LVs (in black).
