Simulation of Mild Wear in Helical Gears
Anders Flodin,Sören Andersson +1 more
TL;DR: In this article, a computer model for simulation of the wear behavior in helical gears has been developed, where the gear teeth are regarded as thin uncoupled slices and the pressure distribution on each slice is calculated using the well-known theories of Hertz assuming an infinitely wide line-contact.

Energy Dissipation Analysis for Elastoplastic Contact and Dynamic Dashpot Models
TL;DR: In this article , the authors analyzed the relationship between the dynamic dashpot and the static force-displacement models used in multibody systems and derived a new hysteresis damping factor based on linearized elastoplastic contact stiffness and energy conservation during impact.

Contact and Rubbing of Flat Surfaces
TL;DR: In this article, the authors compared the deduced dependence of the experimental observables on the load with the experimental evidence and concluded that the most realistic model is one in which increasing the load increases both the number and size of the contact areas.

Contact of Nominally Flat Surfaces
TL;DR: In this article, the authors proposed a new theory of elastic contact, which is more closely related to real surfaces than earlier theories, and showed how the contact deformation depends on the topography of the surface, and established the criterion for distinguishing surfaces which touch elastically from those which touch plastically.

Elastic deformation and the laws of friction
TL;DR: In this paper, the authors examined whether the hypothesis of elastic deformation of surface protuberances is consistent with Amontons's law, that the friction is proportional to the applied load.

The Elastic Contact of Rough Spheres
J. A. Greenwood,J. H. Tripp +1 more
TL;DR: In this article, the Hertzian theory of elastic contact between spheres is extended by considering one of the spheres to be rough, so that contact occurs, as in practice, at a number of discrete microcontacts.

A numerical method for solving rough contact problems based on the multi-level multi-summation and conjugate gradient techniques
I. A. Polonsky,Leon M. Keer +1 more
TL;DR: An alternative numerical method for solving contact problems for real rough surfaces using a single-loop iteration scheme based on the conjugate gradient method, which converges for arbitrary rough surfaces.
