A semantic model-based systems engineering approach for assessing the operational performance of metal forming process
Metal Forming is a basic and essential industrial process to provide materials for constructing complex products. To design an efficient metal forming process, the functional requirements and operational performance are two important aspects to be consider ...
Pergamon-Elsevier Science Ltd2024Large-Scale Hollow-Core 3D Printing: Variable Cross-Section and Printing Features for Lightweight Plastic Elements
Hollow-core 3D printing (HC3DP) proposes a new method for the production of lightweight, material-efficient thermoplastic 3D printed elements. This new fabrication approach promises material savings of 50-80%, while increasing the extrusion rate significan ...
Mary Ann Liebert, Inc2024Diversity of radial spin textures in chiral materials
Oleg Yazyev, Daniel Gosalbez Martinez, Alberto Crepaldi
We introduce a classification of the radial spin textures in momentum space that emerge at the high-symmetry points in crystals characterized by nonpolar chiral point groups (D2, D3, D4, D6, T, O). Based on the symmetry constraints imposed by these point g ...
College Pk2023Simultaneous strength and ductility enhancement of wire-arc directed energy deposited Al-Cu alloy by interlayer laser shock peening
Wire-arc directed energy deposition (wire-arc DED), recognized for its ability to produce large-scale parts, has gained considerable attention. However, a critical issue with this method is the high prevalence of internal porosity defects found in the manu ...
Lausanne2023Augmented-reality-assisted timber drilling with smart retrofitted tools
Yves Weinand, Julien Gamerro, Andrea Settimi
An ordinary electric drill was integrated into a context-aware augmented reality (AR) framework to assist in timber-drilling tasks. This study is a preliminary evaluation to detail technical challenges, potential bottlenecks, and accuracy of the proposed o ...
2022Nondestructive characterization of laser powder bed fusion parts with neutron Bragg edge imaging
Roland Logé, Christian Leinenbach, Markus Strobl, Nikola Kalentics
Laser powder bed fusion is an efficient technique for additive manufacturing of metallic materials. The quality of the material produced depends on the optimization of a large range of build parameters and the complex thermo-mechanical build process is pro ...
ELSEVIER2021Stainless steel-like FeCrNi nanostructures via electrodeposition into AAO templates using a mixed-solvent Cr(III)-based electrolyte
Electrodeposition of stainless steel-like materials such as FeCrNi alloy into micro- and nanotemplates provides a sustainable framework for creating biomedical-oriented micro- and nanocomponents with outstanding characteristics. While Cr(III)-based electro ...
2020The influence of wear on the interaction between the cutting tools and the rock face
At present, the demand of long tunnels with high cover is growing. At these depths, a rock mass consists mainly on hard rocks, which are often excavated with hard rock TBMs, whose costs per meter are lower than conventional excavation methods. The excavati ...
2020Effect of dislocations, Al-3(Sc,Zr) distribution and ageing temperature on theta ' precipitation in Al-Cu-(Sc)-(Zr) alloys
The 2xxx series aluminium alloys, which contain Cu as the main addition element, are widely used in the aerospace industry for their high specific strength. The main strengthening contribution in these alloys comes from the formation of theta' precipitates ...
