[{"abstract":[{"lang":"eng","text":"<jats:p>Abstract. This study presents intrinsic lubrication as a novel approach to deep drawing processes, using additively manufactured, lubricant-permeable tools to minimize lubricant consumption and improve efficiency. Two systems were evaluated: a passive system based on capillary action and gravity, and an active system using pumped delivery for precise, on-demand application. Experimental tests were conducted on micro-bores (0.2-0.5 mm) to demonstrate their suitability for lubricant transport. Smaller bores have excellent capillary action but are prone to clogging, while larger bores offer higher permeability. The passive system is resource-efficient but requires adjustments to counteract gravitational asymmetry. The active system provides consistent lubricant distribution but is more complex. These findings provide a basis for optimizing intrinsic lubrication systems.</jats:p>"}],"publication":"Materials Research Proceedings","type":"conference","department":[{"_id":"156"},{"_id":"321"}],"date_created":"2025-05-14T08:53:41Z","publication_status":"published","date_updated":"2026-04-16T08:33:32Z","intvolume":"        54","title":"Intrinsic lubrication: A new approach in the context of the deep drawing process","year":"2025","publication_identifier":{"issn":["2474-395X"]},"author":[{"id":"79551","last_name":"Cakici","first_name":"Ermir","full_name":"Cakici, Ermir"},{"full_name":"Homberg, Werner","first_name":"Werner","last_name":"Homberg","id":"233"}],"doi":"10.21741/9781644903599-122","main_file_link":[{"url":"https://mrforum.com/product/9781644903599-122/"}],"language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"short":"E.

In particular, the car body offers several opportunities for weight reduction. Multi-material designs are increasingly being applied to select the most suitable material for the respective load and ultimately achieve synergy effects. For example, aluminium castings are used at the nodes of a spaceframe body. Subsequently, these are joined with profiles to form the bodyshell. To join different materials mechanical joining techniques, such as semi-tubular self-piercing riveting, are deployed. According to the current state of the art, cracks occur in the aluminium castings during the mechanical joining process as a result of the high degree of deformation. Although the aluminium casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent castability. In particular, the ability to cast thin structural parts is enabled by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis study addresses the mechanical joining properties of the near eutectic aluminium casting alloy AlSi12, depending on different microstructures. These are achieved by annealing processes and modifying agents. Through an adapted heat treatment, the previously lamellar morphology can be transformed into a globular morphology, which leads to increased ductility and prevents the formation of cracks during the self-piercing riveting (SPR). The joinability is investigated using different die geometries, whereas the joint formation is analysed regarding crack initiation. To evaluate the increased ductility, microstructural and mechanical tests are performed and finally, a microstructure-joinability correlation is established.","lang":"eng"}],"publication":"The Journal of Materials: Design and Applications, Part L","user_id":"7850","publisher":"Sage Publications","_id":"58807","has_accepted_license":"1","status":"public","conference":{"end_date":"2024-07-05","name":"5th International Conference on Materials Design and Applications 2024","start_date":"2024-07-04","location":"Porto, Portugal"},"quality_controlled":"1","project":[{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"name":"TRR 285 – A02: TRR 285 - Subproject A02","_id":"136"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"_id":"146","name":"TRR 285 – C02: TRR 285 - Subproject C02"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"apa":"Neuser, M., Holtkamp, P.

To overcome the limitations of existing finite element tools, a modular Python framework has been developed to automate three-dimensional crack growth simulations. The program combines geometric reconstruction, adaptive remeshing, and the numerical evaluation of fracture mechanics parameters within a single, fully automated workflow. The framework builds on open-source components and remains solver-independent, enabling straightforward integration with commercial or research finite element codes. A dedicated sequence of modules performs all required steps, from mesh separation and crack insertion to local submodeling, stress and displacement mapping, and iterative crack-front update, without manual interaction. The methodology was verified using a mini-compact tension (Mini-CT) specimen as a benchmark case. The numerical results demonstrate the accurate reproduction of stress intensity factors and energy release rates while achieving high computational efficiency through localized refinement. The developed approach provides a robust basis for crack growth simulations of geometrically complex or residual stress-affected structures. Its high degree of automation and flexibility makes it particularly suited for analyzing cracks in clinched and riveted joints, supporting the predictive design and durability assessment of joined lightweight structures."}]},{"abstract":[{"lang":"eng","text":"<jats:p>Abstract. In the development of advanced lightweight automotive solutions, self-piercing riveting (SPR) offers the possibility of joining multi-material structures to fulfil a wide variety of requirements. With regard to the entire process chain, production-related pre-deformations of the parts to be joined can influence the geometric shape and load capacity of SPR joints. Various studies have investigated the influence of pre-stretched sheet materials, in the sense of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching sheet metals on the formation of their geometrical characteristics and the shear-tensile strength of SPR processes was observed [1]. Pre-rolled semi-finished products are also joined together in mixed material automotive structures, e.g. tailor rolled blanks. This work aims to investigate the influence of pre-rolled joining parts on the geometric formation and load-carrying capacity of SPR joints. For this purpose, sheets of metal are cold-formed using a rolling process to induce a defined strain-hardening state in the material and then joined in various combinations. As the degree of deformation increases, the rolling of samples can lead to minimal accumulation of damage in the sheet materials, which can influence the joint behaviour. The rolling process, as well as the subsequent joining process, are also investigated by FEM. The influence of pre-rolled semi-finished products on the strength of the SPR joints is investigated.</jats:p>"}],"publication":"Materials Research Proceedings","department":[{"_id":"157"}],"type":"conference","date_created":"2025-05-13T06:54:20Z","intvolume":"        54","date_updated":"2026-05-13T13:50:44Z","publication_status":"published","publication_identifier":{"issn":["2474-395X"]},"author":[{"full_name":"Schlichter, Malte Christian","first_name":"Malte Christian","last_name":"Schlichter","id":"61977"},{"last_name":"Harabati","first_name":"Özcan","full_name":"Harabati, Özcan"},{"id":"76631","last_name":"Ludwig","first_name":"Jean-Patrick","full_name":"Ludwig, Jean-Patrick"},{"id":"45779","first_name":"Max","last_name":"Böhnke","full_name":"Böhnke, Max"},{"id":"34782","last_name":"Bielak","first_name":"Christian Roman","full_name":"Bielak, Christian Roman"},{"id":"7850","full_name":"Bobbert, Mathias","last_name":"Bobbert","first_name":"Mathias"},{"last_name":"Meschut","first_name":"Gerson","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","id":"32056"}],"year":"2025","title":"Experimental and numerical investigation of the influence of rolling-induced sheet metal deformation on SPR joints","doi":"10.21741/9781644903599-148","language":[{"iso":"eng"}],"project":[{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"quality_controlled":"1","citation":{"apa":"Schlichter, M.

Friction-induced solid-state recycling of aluminum scrap to production endless semi-finished products. Scrap is fed into a continuously rotating wheel. This requires less energy compared to heat-based recycling processes. Different sizes, shapes and surfaces of chips can be used as starting material in the process. The influence of this has been shown in past publications. A native oxide layer is a fixed component of aluminum surface. This layer is broken up during the forming process, allowing the aluminum to bond. In addition to the geometry, the surface finishes and the thickness of the oxide layer are therefore also important input variables in friction-induced solid-state recycling. The oxide layers on the chips were determined for the investigation. In addition, different layer thicknesses were produced to survey their influence. The resulting semi-finished products were evaluated on the basis of their tensile strength and microstructure. The main result of the investigations is the fact that semi-finished products made from chips with thicker oxide layers tend to be more brittle.

Thus, in 2019, the so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized in numerical and experimental studies. Based on this research, a modification of the nozzle design was proposed, which has now been considered in the successor model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation on the particle formation, we operated both burners under identical operating conditions to produce maghemite. The final powder comparison showed that SS2 yielded considerable higher specific surface areas (associated with smaller primary particle sizes), lower polydispersity, and higher phase purity. To obtain further information on the size distributions of aggregates and agglomerates generated by SS2, aerosol samples were extracted by hole in a tube (HIAT) sampling and characterized by scanning mobility particle sizing (SMPS). Samples were extracted along the centerline at different heights above the burner (HAB) above the visible flame tip (>7 cm), and quenching experiments were performed to extract the aerosol samples at different dilution rates. Thereby, it was demonstrated that performing detailed quenching experiments is crucial for obtaining representative HIAT-SMPS data. In particular, agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were not sufficiently diluted. If sufficient dilution was applied, distribution widths and mean particle mobility diameters were determined with high accuracy (sample standard derivation <5 %). Our data suggested the evolution of primary particle sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates present above the visible flame were compact in structure (non- fractal). The mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7 cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52.","lang":"eng"}],"publisher":"Elsevier","_id":"51133","editor":[{"last_name":"Tischendorf","first_name":"Ricardo","full_name":"Tischendorf, Ricardo","id":"67002"},{"id":"98419","last_name":"Massopo","first_name":"Orlando","full_name":"Massopo, Orlando"},{"full_name":"Schmid, Hans-Joachim","last_name":"Schmid","orcid":"000-0001-8590-1921","first_name":"Hans-Joachim","id":"464"},{"last_name":"Pyrmak","first_name":"Olek","full_name":"Pyrmak, Olek"},{"full_name":"Dupont, Sophie","first_name":"Sophie","last_name":"Dupont"},{"full_name":"Fröde, Fabian","first_name":"Fabian","last_name":"Fröde"},{"full_name":"Pitsch, Heinz","last_name":"Pitsch","first_name":"Heinz"},{"full_name":"Kneer, Reinhold","first_name":"Reinhold","last_name":"Kneer"}],"ddc":["660"],"user_id":"98419","status":"public","has_accepted_license":"1","citation":{"apa":"Maghemite nanoparticles synthesis via spray flame synthesis and particle characterization by hole in a tube sampling and scanning mobility particle sizing (HIAT-SMPS).

Due to these advantageous properties, PC is often used in industry for example in medical devices, automotive headlamps, sporting equipment, electronics, and a variety of other products. PC is often subjected to uniaxial and biaxial loading conditions. Therefore, reliable material models have to take into account the various resulting experimental effects. For those reasons, we investigate PC specimens under uniaxial and biaxial loading by using different stretch rates and loading scenarios. In addition to that, we propose methods for optical measurement of local stretches to obtain the approximated local true stress. In future work, the displacement fields and the resulting reaction forces will be used for parameter identification of constitutive equations.</jats:p>"}],"quality_controlled":"1","date_created":"2024-02-29T13:53:13Z","type":"journal_article","keyword":["Electrical and Electronic Engineering","Atomic and Molecular Physics","and Optics"],"department":[{"_id":"9"},{"_id":"154"},{"_id":"321"}]},{"publisher":"Elsevier BV","_id":"52218","volume":290,"user_id":"335","status":"public","citation":{"short":"P.
