TLDR
In this article, it was shown that despite the van der Waals' forces being capable of increasing the elastic contact area between the ball and the plane, the force that is required to overcome the molecular forces arising when the contact is broken does not increase thereby.About:

Force measurements with the atomic force microscope: Technique, interpretation and applications
TL;DR: The atomic force microscope (AFM) is not only used to image the topography of solid surfaces at high resolution but also to measure force-versus-distance curves as discussed by the authors, which provide valuable information on local material properties such as elasticity, hardness, Hamaker constant, adhesion and surface charge densities.

Adhesion of spheres : the JKR-DMT transition using a dugdale model
TL;DR: In this article, the energy release rate G is computed by the J-integral and the equilibrium is given by G = w. To avoid self consistent numerical calculations based on a specific interaction model (Lennard-Jones potential for example) we have used a Dugdale model, which allows analytical solutions.

Discrete particle simulation of particulate systems: Theoretical developments
TL;DR: This paper reviews the work in this area with special reference to the discrete element method and associated theoretical developments, and covers three important aspects: models for the calculation of the particle–particle and particle–fluid interaction forces, coupling of discrete elements method with computational fluid dynamics to describe particle-fluid flow, and the theories for linking discrete to continuum modelling.

The influence of flattening on the adhesion of particles
TL;DR: In this article, a new theory was proposed which considers molecular repulsions and thus properly predicts the minimal nature of the interaction functions and the influence of elastic flattening on the interaction force and energy.

On the role of electrostatic forces in the adhesion of polymer particles to solid surfaces
TL;DR: In this paper, simultaneous measurements of the adhesive force and double electric charge of particles after their removal from a metal surface were made, and a calculation was made of the surface density of charge for the polyvinyl chloride particle-steel system.

Direct measurements of molecular attraction of solids
B.V. Derjaguin,I.I. Abrikossova +1 more
TL;DR: In this article, a photoelectromagnetic negative feedback coupling was used to measure the force of molecular attraction between plane and spherical surfaces of two plates separated by a narrow gap, as a function of the width of this gap.
