A question regarding applying the boundary conditions in thin film peeling

Choose a channel featured in the header of iMechanica: 

Hello all,

As is my understanding that, in analytical models such as "Kendall Peeling Model", when they talk about peeling angle it is the angle at which the peeling force is applied (or am I wrong?). But when it comes to FE analysis, if we displace one end of the film at an angle by applying displacement boundary conditions on that end, the resulting forces are not along the same direction of the displacements. So, I am confused as to how to compare the FE results with that of the analytical models.

Thank you.

Adhesion between a power-law indenter and a thin layer coated on a rigid substrate

Abstract: In the present paper we investigate indentation of a power-law axisymmetric rigid probe in adhesive contact with a "thin layer" laying on a rigid foundation for both frictionless unbounded and bounded compressible cases. The investigation relies on the "thin layer" assumption proposed by Johnson, i.e. the layer thickness being much smaller than the radius of the contact area, and it makes use of the previous solutions proposed by Jaffar and Barber for the adhesiveless case.
