I recently encountered the research of Phil Attard and others, in which the contact problem is solved, relaxing the restrictions of the traditional contact models (Hertz, JKR, DMT) and solving based on a formulation where the governing equations are derived using finite-range surface forces and calculated numerically, self-consistently.
Max penetration error in ABAQUS
Forums
I am doing contact simulation of soft material. I want to change the default criterion for max penetration error, but can't seem to find how to do it. I tried contact controls relative and absolute penetration tolerances, hcrit but that did not affect the error criterion. Can someone help me please?
a couple of recently published papers in contact mechanics -- roughness and dynamic rolling
For those interested in a classical subject like contact mechanics, here are a couple of recent papers published in August. One is an extension of the Greenwood Williamson theory of rough contact, and the other is a linear perturbation solution of the classical Carter rolling contact problem for a rolling cylinder, when the surface is corrugated and hence there are oscillations in both normal and tangential loads.

Rail corrugation: ”one hundred years of solitude”? or a true enigma?
You may remember that I promised some time ago to discuss each of the topics mentioned by Ken Johnson in his Timoshenko Medal speach. Here I take rail corrugation. Rail corrugation has been noticed at least for 100 years, but (particularly short pitch one in the range 20÷80 mm) has been considered an enigma because measured corrugation wavelength did not relate well with wear instabilitymodels.
Predictive modeling schemes for wear in tribometers

Study of wear in complex micro-mechanical components is often accomplished experimentally using a pin-
on-disc and twin-disc tribometer. The present paper proposes an approach that involves a computationally
efficient incremental implementation of Archard’s wear model on the global scale for modeling sliding and
slipping wear in such experiments. It will be shown that this fast simplistic numerical tool can be used to
identify the wear coefficient from pin-on-disc experimental data and also predict the wear depths within a
Adhesion in viscoelastic contacts
Yesterday I had the distinct pleasure of seeing a mechanics seminar delivered "tag-team" by Ken Johnson and Jim Greenwood. (I know several people have thought I was a bit mad for jumping "across the pond" but there are really some amazing benefits of being part of the Cambridge Engineering faculty!)

A normalising loading parameter useful in summarising the mechanical response of plane, pin in plate-like contacts is extended to axisymmetric, ball in socket-like contacts. Various diagrams reporting
