METHOD OF DIMENSIONALITY REDUCTION IN CONTACT MECHANICS AND FRICTION: A USER'S HANDBOOK. II. POWER-LAW GRADED MATERIALS

open access: yesFacta Universitatis. Series: Mechanical Engineering, 2016
Until recently, the only way of solving contact problems was to applythree-dimensional contact theories. However, this presupposes higher mathematical and numerical knowledge, which usually only research groups possess.

Investigations on interface microstructure and strength properties of dissimilar tin bronze/superalloy diffusion bonded joints

open access: yesScience and Engineering of Composite Materials, 2015
Diffusion bonding of dissimilar metals QSn4-3 and GH34 by using a QSn6.5-0.1 interlayer has been conducted in this study. The purpose of the study is to investigate the interface microstructure and strength of the joints, and to demonstrate the ...

Structural friction anisotropy on the nanometer scale [PDF]

open access: yes, 2013
The ability to understand and control friction on an atomic scale is becoming increasingly important, not only considering the increasingly small scale of mechanical systems that are being developed, but also in respect of furthering the fundamental ...

Experimental Verification of the Boundary Element Method for Adhesive Contacts of a Coated Elastic Half-Space

open access: yesLubricants, 2023
We consider analytical, numerical, and experimental approaches developed to describe the mechanical contact between a rigid indenter and an elastic half-space coated with an elastic layer.

Non-contact friction studied with pendulum AFM [PDF]

open access: yes, 2014
Understanding nanoscale friction and dissipation is central to nanotechnology. The recent detection of the electronic friction drop caused by the onset of superconductivity in Nb by means of an ultrasensitive non-contact pendulum atomic force microscope (

Microstructure and mechanical properties of refill friction stir spot welded joints: Effects of tool size and welding parameters

open access: yesJournal of Materials Research and Technology, 2022
A novel refill friction stir spot welding (RFSSW) technique employing large-sized tools is proposed. The microstructure and mechanical properties of joints produced with a large-sized welding tool and a conventional tool are compared.

Voltage-Induced Friction with Application to Electrovibration

open access: yesLubricants, 2019
Due to the growing interest in robotic and haptic applications, voltage-induced friction has rapidly gained in importance in recent years. However, despite extensive experimental investigations, the underlying principles are still not sufficiently ...

Contact mechanics and friction: Role of adhesion

open access: yesFriction
This paper presents an overview of the role of adhesion in various tribological phenomena. We discuss (1) adhesion and adhesive hysteresis in rough contacts, (2) adhesive contribution to dry friction, (3) properties of adhesive contacts under tangential ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Environmental effects on the wear characteristics of phenolic resin composite (Confirmation of water vapor effects and proposal of tribo-degraded gas effects)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
For the purpose of clarifying the water vapor effect on brake pad wear, two experiments were performed. In the first set of experiments, wear tests were conducted using four pads under three relative humidity conditions (0.8%RH, 35%RH and 65%RH).
