Elastic–plastic contact model for rough surfaces based on plastic asperity concept
Jamil Abdo,Kambiz Farhang +1 more
TL;DR: In this paper, a mathematical formulation for the contact of rough surfaces is presented, which is facilitated through the definition of plastic asperities that are assumed to be embedded at a critical depth within the actual surface as perities.
Journal ArticleDOI
Closed-Form Equations for Three Dimensional Elastic-Plastic Contact of Nominally Flat Rough Surfaces
Ali Sepehri,Kambiz Farhang +1 more
TL;DR: In this article, the authors derived closed-form equations governing the shoulder-shoulder contact of asperities based on a generalization by Chang, Etsion, and Bogy.
Journal ArticleDOI
A Nonlinear Model for Structural Vibrations in Rolling Element Bearings: Part I—Derivation of Governing Equations
J. Datta,Kambiz Farhang +1 more
TL;DR: In this article, a nonlinear model for structural vibrations in rolling element bearing is presented, where the contacts between the rolling elements and races are treated as nonlinear springs whose stiffnesses are obtained by application of the equation for Hertzian elastic contact deformation.
Journal ArticleDOI
On Elastic Interaction of Nominally Flat Rough Surfaces
Ali Sepehri,Kambiz Farhang +1 more
TL;DR: In this article, a hybrid interactive/optimization technique is used to derive in approximate closed-form equations relating contact load to mean plane separation, and two sets of approximate equations are found for each of the normal and half-plane tangential force components.
Journal ArticleDOI
Design of spherical 4R mechanisms : Function generation for the entire motion cycle
Kambiz Farhang,Yasir S. Zargar +1 more
TL;DR: In this paper, the theory of small-crank mechanisms is applied to obtain approximate descriptions for the follower angular displacement in terms of the input crank angle, where the follower angle is assumed to comprise a mean and a perturbational motion.
