RISClosure to “Discussion of ‘Experimental Investigation of Fully Plastic Contact of a Sphere Against a Hard Flat’ ” (2007, ASME J. Tribol., 129, p. 700)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The authors thank the reviewers' (Dr. Jackson and Dr. Green) interest in the paper arising several issues for discussion. We agree with the reviewers that even in the fully plastic regime ...
Experimental Investigation of Fully Plastic Contact of a Sphere Against a Hard Flat
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we report the experimental investigation to evaluate the published models for the contact of a deformable sphere against a hard flat in the fully plastic contact regime. A new ...
Stribeck Curve for Starved Line Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses a mixed lubrication model in order to predict the Stribeck curve for starved lubricated line contacts. This model is based on a combination of the contact model of Greenwood ...
On the Frictional Heating in Single Summit Contacts: Towards Failure at Asperity Level in Lubricated Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of surface roughness and thermal conductivity on seizure in lubricated contacts is described in this work by quantifying the action of individual asperities in relation to local ...
Deformation of Rough Line Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of surface roughness on the bulk deformation of line contacts is studied. The model of Greenwood and Tripp (1967) will be extended to line contacts. It is found that the central ...
Application of a Deterministic Contact Model to Analyze the Contact of a Rough Surface Against a Flat Layered Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a rough surface is modeled as an array of asperities represented by spheres with different radii and heights to be able to calculate the deformation (elastic, elastic-plastic, ...
Analysis of Material Transfer From a Soft Workpiece to a Hard Tool: Part I—Lump Growth Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important mechanism reducing the lifetime of the deepdrawing tools is material transfer from the workpiece to the tool, resulting in the buildup of lumps on the tool surface. In this study, ...
Analysis of Material Transfer From a Soft Workpiece to a Hard Tool: Part II—Experimental Verification of the Proposed Lump Growth Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the lump growth model, described in an accompanying paper (de Rooij and Schipper, 2000) is validated by means of experiments performed on a deepdrawing simulator. In the ...
Plastic Deterministic Contact of Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a theoretical and experimental investigation is presented to study the contact behavior of the plastic contact of deterministic rough surfaces. Analyses exclude bulk deformation ...
On the Transitions in the Lubrication of Concentrated Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Friction experiments on lubricated concentrated contracts were performed to study; (a) the transitions between the different lubrication modes when operating in the lubricants liquid-state regime ...
