FIG. 2.

Rate-independent (solid line) and rate-dependent (non-solid lines) evolutions computed, respectively, with the pseudoelastic and the full constrained mixture models, the latter with different characteristic G&R times s_G&R = {0.1, 1, 10} days, for an isolated increase in pressure with s_ext ∼ 10 days. Shown are (a) prescribed load P/P_o from 1 to 1.15, (b) mechano-stimulus function ϒ^c, (c) referential mass densities of collagen ${\rho }_{MR}^c/{\rho }_{Mo}^c={\rho }_{AR}^c/{\rho }_{Ao}^c$, (d) relative inner radius a/a_o, (e) relative medial thickness h_M/h_Mo, and (f) relative adventitial thickness h_A/h_Ao. The final total wall thickness is h = 0.0494 mm (with 67% due to medial thickening and 33% due to adventitial thickening). Finally, shown too is the long-term mechanobiologically equilibrated solution (solid square), which reveals perfect correspondence of all three methods at the final adapted state. The scales are the same in Figs. 2, 3, and 4 to facilitate comparisons.
