Schematic of opening angle experiments. Growth and remodeling in the loaded state (b) produce residual stress in the unloaded state (bu). When a transmural cut is made in the unloaded artery, relief of residual stress results in the opening angle (φ). When a circumferential cut (dashed line) is followed by a radial cut, the inner and outer rings open to different opening angles.
