Fig. A.1.

Prescribed pressure (a) and predicted evolving responses: luminal radius (b), thickness (c and d), circumferential and axial stress in the vessel (e and g) and degradable external support (f and h) for a 1.5-fold increase in pressure. Results for different initial values of the thickness (percent of vessel thickness) of the external polymeric support. Adaptation without an external support (‘none’) is shown for reference. Compare to Fig. 3 (change in material stiffness) and Fig. 4 (change in structural stiffness).
