Figure 2.

Mean shell radius (full line; left y axis) and asphericity (long-dashed line; right y axis) as a function of the internal pressure acting on a shell obtained from the numerical minimization of Eq. 1 with pressure (26) T = 400). The scaled units of pressure $\left(\mathit{\epsilon }/\overline{R}\right)$ are shown on the bottom x axis. The short-dashed line is the theoretical prediction of Eq. 2. The pressures recalculated in standard atmosphere (atm) units are shown on the top x axis. These were obtained by taking Y = 1 k_BT/nm², κ = 10 k_BT, and $\overline{R}=16$ nm, yielding γ = 26, which is the FvK number at which the calculations were performed. The results of a numerical minimization of energy of a shell with T = 3 and same γ are indicated by circles. To see this figure in color, go online.
