TL;DR: In this paper, the authors extend perturbation theory to arbitrary order and compute finite speed corrections to existing results, and investigate the impact of different contact line models on the large-scale shape of the interface.
Abstract: The surface of a liquid near a moving contact line is highly curved owing to diverging viscous forces. Thus, microscopic physics must be invoked at the contact line and matched to the hydrodynamic solution farther away. This matching has already been done for a variety of models, but always assuming the limit of vanishing speed. This excludes phenomena of the greatest current interest, in particular the stability of contact lines. Here we extend perturbation theory to arbitrary order and compute finite speed corrections to existing results. We also investigate the impact of different contact line models on the large-scale shape of the interface.

TL;DR: In this article, the axisymmetric contact between a rigid sphere and an elastic half space was investigated and it was found that when the contact radius is comparable with the ratio of surface tension to elastic modulus, surface tension significantly affects the pressure distribution on the contact region.
