Comparison of local displacements. Verhoeff's stain placed at discrete points on the cruciform surface was tracked (circle) during the mechanical test and compared to the equivalent location in the finite element domain (X). The absolute difference in x and y position between the model and experiment for each step is depicted in the plots. The finite element domain along the free surface (solid line) did not contract as much as the experiment once displacements greater than 1.4 mm occurred.
