Stress comparison in the directions , and for the HO model and its modified version that includes the isochoric part of the strain energy. These curves display the evolution of the stress in terms of the elongation in the direction of the fibers (a), collagen sheet direction (b), normal direction (c), and fiber-collagen sheet direction (d).
