Contact lines on stretched soft solids: modelling anisotropic surface stresses

We present fully analytical solutions for the deformation of a stretched soft substrate due to static wetting large liquid droplet, and compare our recently published experiments (Xu et al, Soft Matter 2018). Following Green's function approach, we extend surface-stress regularized Flamant-Cerruti problem account uniaxial pre-strains substrate. Surface profiles, including heights opening angles ridges, are provided linearized finite kinematics. fit experimental ridge shapes as applied strain using two free parameters, surface Lame coefficients. In comparison with experiments, find that observed more accurately captured kinematics, especially increasing levels pre-strain. These fits qualitatively agree results Xu but revise values elastic constants.
