Simple model for drops on elastic substrates — •Christopher Henkel1, Johannes Kemper1, Jacco Snoeijer2, and Uwe Thiele1 — 1Institut für Theoretische Physik, Münster, Germany — 2Fac. of Science and Technology, Twente, Netherlands
The investigation of the wetting behaviour on viscoelastic or elastic substrates is of great interest. We present a simple model for steady liquid drops on fully compressible elastic substrates, and show that a double transition appears under variation of the substrate softness, similar to the one described in [1]. We further investigate how the transition depends on wettability and how it is amended by the Shuttleworth effect, i.e., the dependency of the interfacial tensions on local strain. Finally, we employ a gradient dynamics model in the long-wave limit and show first results of direct time simulations.
