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