RISDiscussion of “Ghaednia, H., Wang, X., Saha, S., Xu, Y., Sharma, A., & Jackson, R. L. (2017). A Review of Elastic–Plastic Contact Mechanics. Applied Mechanics Reviews, 69(6).”
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been 5 years since this review of elastic-plastic contact mechanics was published. The area still remains very active, and many advancements have been made since then. This discussion summarizes these advances and ...
A Solution of Rigid Perfectly Plastic Cylindrical Indentation in Plane Strain and Comparison to Elastic-Plastic Finite Element Predictions With Hardening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The indentation of flat surfaces deforming in the plastic regime by various geometries has been well studied. However, there is relatively little work investigating cylinders indenting plastically deforming surfaces. This ...
Electrical Contact During a Rolling Vibratory Motion Considering Mixed Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many devices and applications, electrical contacts are exposed to vibrations, sliding, or rolling conditions and are prone to fretting-based degradation. Thus, lubricants are often employed in such contacts to reduce ...
Simplified Formulation for Bush, Gibson, and Thomas Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The random process model, also known as the multi-asperity contact model or statistical model, is one of the dominant methodologies for analyzing the contact between nominally flat rough surfaces. In 1975, Bush, Gibson, ...
The Effect of Nanoparticles on the Real Area of Contact, Friction, and Wear
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although nanoparticle additives have been the topic of multiple studies recently, very little work has attempted to explicitly model the third body contact of nanoparticles. This work presents and uses a novel methodology ...
Periodic Contact Problems in Plane Elasticity: The Fracture Mechanics Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the concept of the fracture mechanics is used to solve the: (i) frictionless purely normal contact and (ii) the similar material contact under the mutual actions of the normal and tangential load. Considering ...
Elastic Contact Between a Geometrically Anisotropic Bisinusoidal Surface and a Rigid Base
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the current study, a semianalytical model for contact between a homogeneous, isotropic, linear elastic halfspace with a geometrically anisotropic (wavelengths are different in the two principal directions) bisinusoidal ...
An Assessment of the Impact of Antishattering Tips and Artifact Removal Techniques on Bulk Cloud Ice Microphysical and Optical Properties Measured by the 2D Cloud Probe
Publisher: American Meteorological Society
Abstract: recent study showed that the ratio of the number of distribution functions derived from 2D cloud probes (2DCs) with standard tips to those with antishatter tips used during the 2008 Indirect and Semidirect Aerosol Campaign ...
Vegetation–Climate Feedbacks in the Conversion of Tropical Savanna to Grassland
Publisher: American Meteorological Society
Abstract: Tropical savannas have been heavily impacted by human activity, with large expanses transformed from a mixture of trees and grasses to open grassland and agriculture. The National Center for Atmospheric Research (NCAR) ...
Some Closed-Form Results for Adhesive Rough Contacts Near Complete Contact on Loading and Unloading in the Johnson, Kendall, and Roberts Regime
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, generalizing the solution of the adhesiveless random rough contact proposed by Xu, Jackson, and Marghitu (XJM model), the first author has obtained a model for adhesive contact near full contact, under the Johnson, ...
