Contact mechanics and friction: Role of adhesion
FrictionThis paper presents an overview of the role of adhesion in various tribological phenomena. We discuss (1) adhesion and adhesive hysteresis in rough contacts, (2) adhesive contribution to dry friction, (3) properties of adhesive contacts under tangential ...

Influence of Chemical Heterogeneity and Third Body on Adhesive Strength: Experiment and Simulation
Frontiers in Mechanical Engineering, 2021 We investigate experimentally and numerically the influence of chemical heterogeneity and of third-body particles on adhesive contact. Chemical heterogeneity is generated by chemical treatment of the contacting bodies changing locally the surface energy.

Superhydrophobic frictions [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance The matchless mobility of water on superhydrophobic materials is often considered as the hallmark of water repellency. The friction of drops is indeed found to be unusual: instead of observing classical friction such as due to contact line and liquid viscosity, we show that the main source of resistance to the water motion arises

INDENTATION OF FLAT-ENDED AND TAPERED INDENTERS WITH POLYGONAL CROSS-SECTIONS
Facta Universitatis. Series: Mechanical Engineering, 2016 Using the Boundary Element Method, we numerically study the indentation of prismatic and tapered indenters with polygonal cross-sections. The contact stiffness of punches with flat bases in the form of a triangle and a square as well as a number of ...

Friction in Adhesive Contact Between a Rough Hard Indenter and Smooth Soft Elastomer Layer
MachinesThe friction between a hard steel indenter and a soft elastomer is studied experimentally. To investigate the influence of roughness, a series of experiments was conducted utilizing an indenter with varying degrees of surface roughness. There is a strong
