Adhesive contact of a compliant sphere to an elastic coated substrate: the thin film limit
Experimental results for adhesive contacts on substrates coated with elastomeric thin films have recently been obtained by C. Tardivat and L. Léger (J. Adhesion Sci. Technol. 15 10551078 (2001)) by the so-called JKR test, which provides both adhesion energy and elastic modulus. These data show that on substrates coated with thin films the adhesion and effective elastic modulus of the sphere dep...
متن کاملAdhesive Contact During the Oblique Impact of Elastic Spheres
An integral representation is developed for the distribution of tangential traction duringadhesive contact between obliquely loaded elastic spheres of similar materials. It is shown thatadhesive conditions arise at the beginning of an impact between two spheres at low angles ofincidence or after an initial period of gross slip for larger angles.A differential equation is dev...
متن کاملRole of Surface Roughness in Hysteresis during Adhesive Elastic Contact.
In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) vs. indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelas...
متن کاملUsing the Dugdale approximation to match a specific interaction in the adhesive contact of elastic objects.
In the Maugis-Dugdale model of the adhesive contact of elastic spheres, the step cohesive stress sigma(0) is arbitrarily chosen to be the theoretical stress sigma(th) to match that of the Lennard-Jones potential. An alternative and more reasonable model is proposed in this paper. The Maugis model is first extended to that of arbitrary axisymmetric elastic objects with an arbitrary surface adhes...
متن کاملStrength statistics of adhesive contact between a fibrillar structure and a rough substrate.
Equal distribution of load among fibrils in contact with a substrate is an important characteristic of fibrillar structures used by many small animals and insects for contact and adhesion. This is in contrast with continuum systems where stress concentration dominates interfacial failure. In this work, we study how adhesion strength of a fibrillar system depends on substrate roughness and varia...
