Abstract:

The propagation of fractures in a solid undergoing cyclic loadings is known as the {\it fatigue phenomenon}. In this paper, we present a time continuous model for fatigue, in the special situation of the debonding of thin layers, coming from a time discretized version recently proposed by A. Jaubert and J.-J. Marigo \cite{M}. Under very general assumptions on the surface energy density and on the applied displacement, we discuss the well-posedness of our problem and we give the main properties of the evolution process.
