a–h Predicted shape changes with the applied strain ε in the samples of spheroidal (a–d) and saddle shapes (e–h). a, e Front-view profile. b, f Top-view profile. c, g Side-view profile. d, h Overlapping of FEM simulation results (contours of the maximum principal strain εmax) with the experimental image at ε = 0.30 (d) and 1.47 (h). Scale bars = 10 mm.
