Effects of the Interphase on the Mechanical Behavior of Thin Adhesive Films – a Modeling Approach

Abstract

In the present conribution, we develop a continuum-based model to describe experimentally observable interphases in thin adhesive films. The model is based on an extended contiuum theory, i.e. the mechanical behaviour in these interphases is captured by an additional field equation. The introduced scalar order parameter models the microscopical mechanical properties of the film phenomenologically.As the film properties at the boundary to the substrate are thought to be extrinsic quantities, they are prescribed as Dirichlet-type boundary conditions in the present model.
