Mech. 2017;84(7):071005-071005-5. doi:10.1115/1.4036776 Figure Legend: Contact radius as a function of applied pressure for w0 = 1 and a range of adhesion energy. The lowest curve indicates loading with θ = 0 or unloading with γ = 0. The forbidden area requires θ < 0 and is nonphysical. Curve DHP with γ = 5 corresponds to that shown in Figs. 2 and 3. The thick black curve is a special case with γ† = 9.98 and pull-off occurs when the “pull-off” pressure reduces to zero. “Pull-off” for γ = 14 occurs at P′ with a suction. All curves terminates at “pull-off” where (∂c/∂p) → ∞, and the locus is shown as gray dashed curve APP†P′.
