MEASURING INTERFACIAL ADHESION BETWEEN A SOFT VISCOELASTIC LAYER AND A RIGID SURFACE USING A PROBE METHOD

摘要: A reliable measure of the adhesion between a very deformable material and solid surface is rather difficult, since interface boundary conditions bulk deformation layer are closely nonlinearly coupled. In this article, new methodology to assess soft viscoelastic on proposed, where we have used specific experimental geometry minimizing layer. flat-ended probe first put in contact with thin removed at constant velocity. The then stopped preset level tensile force time for complete debonding from measured. For our model system, comprised acrylic removable adhesive silicone-coated surface, higher applied faster interfacial fracture occurs, leading an curve energy as function average crack We find that relatively simple ...
