In typical metallic contacts, stresses are very high and result in yielding of the material.
Therefore, the study of contacts which include simultaneous elastic and plastic deformation …

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 …

We carry out a statistically meaningful study on self-affine rough surfaces in elastic
frictionless non-adhesive contact. We study the evolution of the true contact area under …

Contact problems are central to Solid Mechanics, because contact is the principal method of
applying loads to a deformable body and the resulting stress concentration is often the most …

Cracks in brittle solids induced by pyramidal indenters are ideal for toughness evaluation
since the indentation stress fields decay rapidly from the contact center and any cracks will …

The current work considers the multi-scale nature of surface roughness in a new model that
predicts the real area of contact and surface separation as functions of load. This work is …

The goal of this paper is to provide the foundation for an analysis of contact between elastic–
plastic solids, whose surface roughness is idealized with a Weierstrass profile. To this end …

Due to the existence of multiple scales of features on surfaces, during the past two decades
models have been developed that employ a fractal description of the rough surface profile …

Contact area plays a central role in continuum theories of friction and adhesion, and there is
growing interest in calculating it with atomic resolution. Molecular dynamics simulations are …

The particle collision on a wall with roughness is common in nature and industries, but not
well understood yet. The presence of surface roughness greatly increases the complexity of …
