Relation between interfacial separation and load: a general theory of contact mechanics.
I study the contact between a rigid solid with a randomly rough surface and an elastic block with a flat surface. I derive a relation between the (average) interfacial separation u and the applied normal squeezing pressure p. I show that, for nonadhesive interaction and small applied pressure, p approximately exp(-u/u(0)), in good agreement with recent experimental observations.
متن کاملContact mechanics
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 critical point in the body. Contact is characterized by unilateral inequalities, describing the physical impossibility of tensile contact tractions (except under special circumstances) and of material interpenetr...
متن کاملElastic contact mechanics: percolation of the contact area and fluid squeeze-out.
The dynamics of fluid flow at the interface between elastic solids with rough surfaces depends sensitively on the area of real contact, in particular close to the percolation threshold, where an irregular network of narrow flow channels prevails. In this paper, numerical simulation and experimental results for the contact between elastic solids with isotropic and anisotropic surface roughness a...
متن کاملQuasistatic Elastic Contact with Adhesion
The aim of this paper is the variational study of the contact with adhesion between an elastic material and a rigid foundation in the quasistatic process where the deformations are supposed to be small. The behavior of this material is modelled by a nonlinear elastic law and the contact is modelled with Signorini’s conditions and adhesion. The evolution of bonding field is described by a nonlin...
متن کاملSolving Contact Mechanics Problems with PERMON
PERMON makes use of theoretical results in quadratic programming algorithms and domain decomposition methods. It is built on top of the PETSc framework for numerical computations. This paper describes its fundamental packages and shows their applications. We focus here on contact problems of mechanics decomposed by means of a FETI-type nonoverlapping domain decomposition method. These problems ...
