Stretch-stress curves in 3-protocol numerical stretch-controlled tensile experiments for (1) strip biaxial tension in the circumferential direction (a), (d), (g) and (j); (2) equi-biaxial tension (b), (e), (h) and (k); (3) strip biaxial tension in the longitudinal direction (c) (f) (i) and (l). The comparison of “true” and estimated curves for one patient is in the same row, i.e., (a)(b)(c) for AsAA1, (d)(e)(f) for AsAA2, (g)(h)(i) for AsAA3, (j), (k)(l) for AsAA4.
