Figure 3. Functional adaptation in arteries: change of the unloaded geometry with the internal pressure P (left); resulting distribution of residual (right, top) and optimal Cauchy stresses (right, bottom).

We set r_o = 2.34 mm, r_i = 1.87 mm, P/μ = 2.38 from the experimental data in³⁸, giving R_o = 1.92 mm and R_i = 1.3 mm.
