The influence of the indenter tip-radius on indentation testing of brittle materials [PDF]

, 1999
Indentation testing of a brittle material using a notionally ‘sharp’ indenter may reveal several important physical properties, including fracture toughness, surface finish information and the residual stress state. In the case of shallow cone indenters,

Tribological Behavior of Anodized Aluminum Oxide (AAO) Under the Addition of PAO6 Lubrication with Nano-Alumina

Lubricants
Anodizing can generate porous wear-resistant layers, which can act as reservoirs for gradually releasing lubricants. Studies on the formation of zinc dialkyl dithiophosphate (ZDDP) tribofilms in non-ferrous metals are relatively rare. Furthermore, adding

Comparison of medial tibiofemoral joint mechanics between all-suture anchors and transtibial pullout technique for posterior medial meniscal root tears

Journal of Orthopaedic Surgery and Research, 2023
Background The posterior medial meniscal root tear (PMMRT) seriously impacts the tibiofemoral joint biomechanics. Two available techniques for PMMRT repair include the transtibial pullout (TPO) repair and all-suture anchor (ASA) repair techniques.

Contact mechanics perspective of tribology [PDF]

, 2021
A time to throw stones and a time to gather stones (Ecclesiastes 3:5) It is a time to gather stones... The main idea behind this Research Topic is to show to what extent one can understand tribology with macroscopic contact mechanics.

Finite element based surface roughness study for ohmic contact of microswitches [PDF]

, 2012
Finite element method (FEM) is used to model ohmic contact in microswitches. A determinist approach is adopted, including atomic force microscope (AFM) scanning real contact surfaces and generating rough surfaces with three-dimensional mesh.

Curvilinear virtual elements for contact mechanics [PDF]

, 2020
The virtual element method (VEM) for curved edges with applications to contact mechanics is outlined within this work. VEM allows the use of non-matching meshes at interfaces with the advantage that these can be mapped to a simple node-to-node contact ...

Sliding Wear Behavior of WP7V Tool Steel with Different Hardnesses Under Reciprocating Test Rig

Lubricants
This study involved the investigation of the mechanical and tribological behaviors of DIN 1.2344 and WP7V tool steels, quenched in a salt bath after austenitization at 1050 °C, followed by triple tempering for 2 h. The selection of tempering temperatures

A 3D study of the contact surface developed by the contact between the tires and the structural pavements

Exacta, 2009
The basic aim in this work is to present a new technique to analyze the contact surfaces developed by the contact between the tires and the structural pavements by numerical simulations, using 3D finite element formulations with contact mechanics.

On Applications of Semi-Analytical Methods of Contact Mechanics

Frontiers in Mechanical Engineering, 2020
This paper is concerned with possible applications of semi-analytical methods of frictional contact mechanics. The semi-analytical solutions, such as the Method of Memory Diagrams, enable the load-displacement relationship for contact of two axisymmetric

Defining True Tribological Contact Through Application of the Morphological Method to Surface Topography [PDF]

, 2013
In tribological functions high peaks (summits) in the surface topography play a dominant role in that they determine the position of first contact and how the contact will occur.
