(a) Axial and (b) circumferential stretch ratios as a function of axial position for vessels constrained by needles having diameters equal to 0.8, 0.9, or 1.0 times the specimen diameter. All vessels had lengths of 4.05 mm, were pressurized at 13 kPa, and were stretched axially to n-t-n ratios of 1.0 or 1.15.
