On the Degree of Irreversibility of Friction in Sheared Soft Adhesive Contacts

Submitted by Antonio Papangelo on

Adhesion and fracture; adhesion; contact mechanics; friction;

A number of authors have experimentally assessed the influence of friction on adhesive contacts, and generally the contact area has been found to decrease due to tangential shear stresses at the interface. The decrease is however generally much smaller than that predicted already by the Savkoor and Briggs 1977 classical theory using “brittle” fracture mechanics mixed mode model extending the JKR (Griffith like) solution to the contact problem.

Superior biomimetic nacreous bulk nanocomposites by a multiscale soft-rigid dual-network interfacial design strategy, Chen, Gao, et al., Yu, Matter, 2019

 

Novelty/impact/significance:

 

A multiscale soft-rigid dual-network interfacial design strategy produces nacre-like bulk composites with superior mechanical properties, improved stabilities in high humidity and temperature, and the process is a facile, efficient, and scalable fabrication.

Does the loading apparatus stiffness affect the equilibrium of soft adhesive contacts under shear?

Adhesion and fracture; adhesion; contact mechanics; friction;

The interaction between contact area and frictional forces in adhesive soft contacts is receiving much attention in the scientific community due to its implications in many areas of engineering such as surface haptics and bioin-spired adhesives. In this work, we consider a soft adhesive sphere that is pressed against a rigid substrate and is sheared by a tangential force where the loads are transferred to the sphere through a normal and a tangential spring, representing the loading apparatus stiffness.
