Adhesive (eg van der Waals) forces were not generally taken into account in contact
mechanics until 1971, when Johnson, Kendall and Roberts (JKR) generalized Hertz'solution …

This review article focuses on the modeling of complex granular flows employing the
discrete element method (DEM) approach. The specific topic discussed is the application of …

The frictional properties of a rough contact interface are controlled by its area of real contact,
the dynamical variations of which underlie our modern understanding of the ubiquitous rate …

The contacts between cohesive, frictional particles with sizes in the range 0.1–10 μm are the
subject of this study. Discrete element model (DEM) simulations rely on realistic contact …

The strain energy release rate G and its derivative delta G/delta A are used to provide a
general picture of the adherence of viscoelastic bodies. Two bodies in contact on an area A …

Directional arrays of branched microscopic setae constitute a dry adhesive on the toes of
pad-bearing geckos, nature's supreme climbers. Geckos are easily and rapidly able to …

This paper describes a fluidised bed model developed from the DEM-based Aston granular
dynamics code in which the solid–solid interaction rules are based on theoretical contact …

Additive manufacturing (AM) or 3D printing is beginning to mature from a rapid prototy** to
an industrial production technology. However, there are still a lot of fundamental questions …

The paper considers the load—displacement behaviour at the contact of two adhered elastic
spheres under combined normal and tangential loading. The first part of the paper deals …

ABSTRACT The AlCoCrFeNi2. 1 eutectic high-entropy alloys (EHEAs) were prepared using
selective laser melting (SLM) to study the tribological properties at high temperatures …
