Deformation of an elastic substrate by a three-phase contact line.
Young's classic analysis of the equilibrium of a three-phase contact line ignores the out-of-plane component of the liquid-vapor surface tension. While it is expected that this unresolved force is balanced by the elastic response of the solid, a definitive analysis has remained elusive because of an apparent divergence of stress at the contact line. While a number of theories have been presente...
متن کاملAdhesive contact of a compliant sphere to an elastic coated substrate: the thin film limit
Experimental results for adhesive contacts on substrates coated with elastomeric thin films have recently been obtained by C. Tardivat and L. Léger (J. Adhesion Sci. Technol. 15 10551078 (2001)) by the so-called JKR test, which provides both adhesion energy and elastic modulus. These data show that on substrates coated with thin films the adhesion and effective elastic modulus of the sphere dep...
متن کاملContact-line instabilities of driven liquid films
Liquid-film contact lines driven over a surface (substrate) by gravity, centrifugal force, Marangoni force, or wind, exhibit a wealth of instabilities that control many coating and cleaning processes. Starting from a sheet with an approximately straight contact line advancing over the substrate, these instabilities lead to fingering of the sheet to form rivulets, meandering and oscillation of t...
متن کاملContact line instabilities of thin liquid films.
We present results of fully nonlinear time-dependent simulations of a thin liquid film flowing down an inclined plane. Within the lubrication approximation, and assuming complete wetting, we find that varying the inclination angle considerably modifies the shape of the emerging patterns (fingers versus sawtooth). Our results strongly suggest that the shape of the patterns is not necessarily rel...
