Equilibrium of an elastically confined liquid drop
[Under construction -- Nick Schade]
The authors examine the behavior of a liquid drop confined between a rigid substrate from below and an elastic plate from above. The drop will spread and thin between the plates, while also pulling the flexible sheet down. The authors work out theoretical predictions for the shape of the elastic sheet subject to physical and geometric boundary conditions. A few interesting cases are noted, which correspond to different boundary conditions. Experimental data is provided which corroborates the theoretical predictions, and the authors discuss the application of the analysis to subjects as varied as Chinese calligraphy and the stiction of microcantilevers.
