Similar to Figs. 3 and 4 except for different sheath opening angles $Φo$ (i)–(iv) for a fixed core shear modulus. Each subpanel again varies core thickness $Hc$ (represented by progressively darker shading on the curves and local arrows) and sheath thickness $Hs$ (abscissa) and shows (a) average core stress $tcavg$⁠, (b) radial compliance $Δri*/ΔP$⁠, and (c) diastolic radius $ri*$⁠. Note the absences of swelling of the core.
