Free energy of a bubble on a cantilever sheet in large deflection.
(a) The dimensionless free energy curves of bubble on the sheet with different deflections in 2D. (b) The dimensionless free energy curves of a bubble on the sheet with different deflections in 3D. The Young’s contact is selected as θY = 88.4°. Insets are the simulated pictures of the bubble in the cantilever sheet. Both in (a) and (b), the three groups, i.e., lines 1 & 6, lines 2 & 5 and lines 3 & 4 correspond to the case that the external force P = 0.26, 0.19 and 0.12 N, respectively. Solid lines 1, 2, 3 and dashed lines 4, 5, 6 correspond to the convex and concave side, respectively.
