Does stretching affect adhesion?

The adhesion between a solid and a stretched elastic material is known to be reduced as compared to the unstretched situation. We show that computing the elastic deformation by use of the Lagrangian coordinates explains existing experimental results on stretched rubbers for solids with simple geometries, without any need for altering the surface energy. In other words, we show that for such materials, adhesion at a molecular scale (surface energy) is not a!ected by stretching, although adhesion at a macroscopic scale is changed due to the elastic response of the material.
