Normalized area dilatation ΔA/Av as a function of Ri/Rad. The theoretically calculated relationship of the normalized area dilatation (ΔA/Av) as a function of Ri/Rad according to Equations 1 and 2 is shown as a solid black line. The lateral tension resulting from the area dilatation was calculated using Equation 3 and 4 with KA = 265 mN/m, κ = 21 kBT and σ0 = 10−5 N/m (green line).
