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 ...
Ball-on-flat linear reciprocating tests: Critical assessment of wear volume determination methods and suggested improvements for ASTM D7755 standard
(Elsevier B.V., 2021)
This work presents a critical assessment of wear volume determination methods for ball-on-flat linear reciprocating sliding tribological tests. It revealed that the ASTM D7755-11 standard leads to the highest relative ...
The Interaction between the Sheet/Tool Surface Texture and the Friction/Galling Behaviour on Aluminium Deep Drawing Operations
(MDPI, 2021)
The increasing demands for lightweight design in the transport industry have led to an extensive use of lightweight materials such as aluminium alloys. The forming of aluminium sheets however presents significant challenges ...
Bactericidal Surfaces: An Emerging 21st Century Ultra-Precision Manufacturing and Materials Puzzle
(AIP Publishing, 2021)
Progress made by materials scientists in recent years has greatly helped the field of ultra-precision manufacturing. Ranging from healthcare to electronics components, phenomena such as twinning, dislocation nucleation, ...
Chondroitin and Dermatan Sulfate Bioinks for 3D Bioprinting and Cartilage Regeneration
(Wiley, 2022)
Cartilage is a connective tissue which a limited capacity for healing and repairing. In this context, osteoarthritis (OA) disease may be developed with high prevalence in which the use of scaffolds may be a promising ...
Contact pressure and sliding velocity ranges in sheet metal forming simulations
(2021)
In the last few years many efforts have been carried out in order to better understand what the real contact between material and tools is. Based on the better understanding new friction models have been developed which ...
Faktore klimatikoen degradazioaren efektua igogailuetako kable-polea trakzio sistemaren adherentzian
(Tecnalia, 2021)
Igogailuak trakzionatzeko existitzen diren hainbat metodoen artean kable eta polea bidezko trakzio-sistema oso arrunta da. Trakzio-sistema honetan kablearen eta polearen arteko itsaspenak berebiziko garrantzia du, eta ...
Towards tailored surface topography on electrospun wound dressings for exudate absorption
(Emerald, 2024)
Since electrospinning can generate micro- to nanometre-scale fibres, it is widely used for fabricating wound dressings. Electrospun scaffolds with defined three-dimensional patterns at the mat surface can be efficiently ...
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 ...
