Abstract

This article is placed in the context of research on the propagation of a crack in a three-dimensional elastic medium loaded by a viscous fluid. We propose here a simplified version of the problem: the spreading of a drop of viscous fluid placed at the interface between an elastic film and the rigid substrate on which it rests initially, leading to a subsequent local detachment of the film. The main goal is to write a set of equations modeling the spreading of the drop, taking into account different aspects of the phenomenon, as the coupling between the solid and the fluid and the definition of the contact area, to describe the evolution of the fluid drop shape as a function of time.
