Investigation on Physics-based Multi-scale Modeling of Contact, Friction, and Wear in Viscoelastic Materials with Application in Rubber Compounds
… in viscoelastic materials. The multiscale temperature rise of the rubber surface due to hysteresis friction is also modeled and the effect of flash temperature on the real contact area and friction coefficient is studied. Since the hysteresis friction is not the only mechanism involved in …

Nanotribology and Nanomechanics Including Nanomechanical Properties, Adhesion and Surface Roughness With Application to Magnetic Storage Hard Disk Drives
… effect of adhesion, effect of roughness and flash temperature was performed to study the impact between slider corner and disk surface. The above contact mechanics based analysis was validated by a 3-dof, dynamic, thermomechanical finite element analysis.

Infrared radiometric measurements of surface temperatures generated by friction of sliding iron-on-sapphire
Experimental measurements of surface temperatures produced during dry sliding contact were made by using an advanced infrared microscope which receives radiation from a very small target area e.g., 1.78 x 10⁻⁵m in diameter for a 36X objective, allowing temperature measurements within a general …

ROLLING CONTACT FATIGUE BEHAVIOUR OF CASE-CARBURISED STEELS
… produced due to rolling contact loading (Flash temperature) using X-ray diffraction technique. Measurements of carbon gradient using spectrographic technique suggest a carbon depletion in the surface layers. Finally, the possible correlation of these changes microstructure residual stress, …

Understanding phase transformations during flash sintering
… factors in research for materials science. Flash sintering is both a method to densify ceramics within seconds and a method to rapidly synthesize materials. With the ability to use volatile precursors, avoid complete oxidation of elements, and locally cause transformations, flash sintering …

Molecularly thin rheological and contact interfaces
… that the lubricant layer can provide depends on temperature, viscosity of the lubricant, sliding velocity and radius of gyration of the lubricant molecules. This study shows that viscosity has the greatest effect on the load bearing capacity of the molecularly thin lubricant. Thus, by controlling …

Numerical Simulation of Contacts Working Under Mixed Lubricating Conditions
… significantly influenced by contact mechanisms, flash temperature and tribo-chemistry reactions. However, in this study, the focus has been solely on numerically simulating the fluid flow around asperity contacts without considering the contact mechanics or the tribofilms forming between …

Fast GC: Applications and Theoretical Studies
… the optimum linear carrier gas velocity and the temperature. The second part of this work explores the scope and limitations of fast temperature programming in the fast GC analyses of various sample types. These samples included polycyclic aromatic hydrocarbons (PAHs), hydrocarbons and food …

Dynamic and quasi-static contact and scratch analysis of micro-nanoscale thin solid films with application to magnetic storage hard disk drives
With current demand for decreased size of micro/nanoscale systems, coupled with increased mobility, critical understanding of the ensuing contact or impact related behavior of thin solid films used in these systems is of paramount importance for improved design and reliability. In modern …
