This paper discusses the influence of surface energy on the contact between elastic solids. Equations are derived for its effect upon the contact size and the force of adhesion between two lightly loaded spherical solid surfaces. The theory is supported by experiments carried out on the contact of rubber and gelatine spheres.

Surface energy and the theory of the friction of solids

An analysis shows that surface energy may be the dominant parameter in the theory of solid friction through its influence on the real area of contact. This view is compatible with current adhesion

The force of adhesion between solid surfaces in contact

When two elastic solids of known interfacial and surface energies are placed in contact, various types of force are involved. It is shown that both the adhesive force and the peripheral attractive

Adhesion of viscoelastic bodies

The influence of surface energy on the contact between viscoelastic bodies is investigated. An equation is derived for its effect upon the contact zone after reaching the equilibrium position. As an

Elastic contact between nominally plane surfaces in the presence of roughness and adhesion

The solution of the problem of interaction with regard to the forces of adhesive (molecular) attraction of two nominally plane half-spaces one of which is elastic and the surface of the other has a

Elastic Flattening and Particle Adhesion

The effect of elastic flattening on particle adhesion to solid surfaces has been investigated. The attracting and repulsing molecular potential energies and forces are obtained for a flattened

Surface charge and the contact of elastic solids

Contact between a metal sphere and plane specimens of a synthetic polymer has been investigated experimentally. The area of contact has been determined, for a range of contact loads, by measurement

The effect of surface topography on the adhesion of elastic solids

A study of the influence of surface roughness on the net work of adhesion when a smooth, high viscoelastic solid is first brought into contact with and then pulled away from a roughened Perspex

The adhesion of particles undergoing an elastic-plastic impact with a surface

A new model is presented which describes the adhesion of a particle to a surface following an elastic-plastic impact. The experimental testing of the model is described and it is shown that use of



LXXIX. The cohesive force between solid surfaces and the surface energy of solids

Summary An expression is obtained for the cohesive force between two unequal spheres in geometrical contact. From the constant in this expression the surface energy of the solid may be computed.

The Friction and Lubrication of Solids

Originally published in 1950, this classic book was a landmark in the development of the subject of tribology. For this edition, David Tabor has written a new preface, reviewing the many advances

Surface energy of solids

At least five conclusions may be formulated after perusing this review. 1. No method so far suggested for measuring the surface energy or surface tension of solids is satisfactory. 2.
