On the Role of Contact and System Stiffness in the Measurement of Principal Variables in Fretting Wear Testing
(MDPI AG, 2020)
In this work, the role of the contact stiffness in the measurement of principal variables in fretting wear tests is assessed. Several fretting wear tribometers found in the literature, including one developed by the authors, ...
Surface integrity of additive manufacturing parts: a comparison between optical topography measuring techniques
(Elsevier B.V., 2020)
Additive Manufacturing (AM) presents significant industry-specific advantages allowing the creation of complex geometries and internal features that cannot be produced using conventional manufacturing processes. However, ...
A coupled 3D wear and fatigue numerical procedure: Application to fretting problems in ultra-high strength steel wires
(Elsevier Ltd., 2021)
This work presents a coupled 3D wear and fatigue numerical procedure for fretting problems in ultra-high strength steel wires that combines Archard’s wear equation with the Smith–Watson–Topper parameter to predict crack ...
Towards the automation of the die spotting process: Contact blue pattern decryption
(Elsevier Ltd., 2020)
Automotive die spotting is one of the most complex and least standardized processes in the tool making process. A spotting expert identifies local contact areas through a blue-paste pattern and the die/sheet contact is ...
Numerical study of advanced friction modelling for sheet metal forming: influence of the die local roughness
(Elsevier Ltd., 2022)
Numerical simulation of sheet metal forming processes has become indispensable in the last decades. Although the complexity of the frictional behaviour is identified as a key factor for the prediction accuracy, the industry ...
Numerical methodology based on fluid-structure interaction to predict the residual stress distribution in glass tempering considering non-uniform cooling
(Elsevier, 2022)
In this paper a novel numerical methodology for calculating non-uniform residual stress distributions during the glass tempering process is presented. Tempering techniques lead to non-uniform heat transfer rates causing ...
Challenges and issues in continuum modelling of tribology, wear, cutting and other processes involving high-strain rate plastic deformation of metals
(Elsevier Ltd., 2022)
Contribution of finite element method (FEM) as a modelling and simulation technique to represent complex tribological processes has improved our understanding about various biomaterials. This paper presents a review of the ...
Impact of surface roughness on the coefficient of friction of polymer-on-polymer contacts for deflection pulley-rope systems in the lift industry
(Springer, 2024)
The coefficient of friction (CoF) between the deflection pulley and rope in a lift strongly affects the life span of the rope. Although surface roughness is a key factor affecting the metallic pulley–rope CoF, its effect ...
Influence of turning parameters on residual stresses and roughness of 42CrMo4 + QT
(Springer, 2024)
Residual stresses and surface roughness have been recognized to play a critical role in the fatigue strength of metal components. Machining processes can induce different roughness and residual stress conditions depending ...
Turning of 42CrMo4+QT under different scenarios: dataset of machining, roughness and residual stress
(Elsevier, 2024)
The turning process remains one of the most widely used manufacturing methods in the industry due to its high flexibility and production rates. Despite being an extensively used technique, the impact of this machining ...
