As a consequence of the resulting need for multi-material design, mechanical joining technologies become increasingly important. Mechanical joining allows for the combination of dissimilar materials, while thermic joining techniques reach their limits. Self-piercing riveting enables the joining of dissimilar materials by using semi-tubular rivets as mechanical fasteners. The rivet production, however, is costly and time-consuming, as the rivets generally have to be hardened, tempered and coated after forming, in order to achieve an adequate strength and corrosion resistance. A promising approach to improve the efficiency of the rivet manufacturing is the use of high-strength high nitrogen steel as rivet material because these additional process steps would not be necessary anymore. As a result of the comparatively high nitrogen content, such steels have various beneficial properties like higher strength, good ductility and improved corrosion resistance. By cold bulk forming of high nitrogen steels high-strength parts can be manufactured due to the strengthening which is caused by the high strain hardening. However, high tool loads thereby have to be expected and are a major challenge during the production process. Consequently, there is a need for appropriate forming strategies. This paper presents key aspects concerning the process design for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel. The aim is to produce the rivets in several forming stages without intermediate heat treatment between the single stages. Due to the high strain hardening of the material, a two stage forming concept will be investigated. Cup-backward extrusion is chosen as the first process step in order to form the rivet shank without forming the rivet foot. Thus, the strain hardening effects in the area of the rivet foot are minimized and the tool loads during the following process step can be reduced. During the second and final forming stage the detailed geometry of the rivet foot and the rivet head is formed. In this context, the effect of different variations, for example concerning the final geometry of the rivet foot, on the tool load is investigated using multistage numerical analysis. Furthermore, the influence of the process temperature on occurring stresses is analysed. Based on the results of the investigations, an adequate forming strategy and a tool concept for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel are presented."}]},{"status":"public","volume":14,"user_id":"53912","_id":"19973","page":"417-423","quality_controlled":"1","citation":{"bibtex":"@article{Uhe_Kuball_Merklein_Meschut_2020, title={Improvement of a rivet geometry for the self-piercing riveting of high-strength steel and multi-material joints}, volume={14}, DOI={<a href=\"https://doi.org/10.1007/s11740-020-00973-w\">10.1007/s11740-020-00973-w</a>}, journal={Production Engineering}, author={Uhe, Benedikt and Kuball, Clara-Maria and Merklein, Marion and Meschut, Gerson}, year={2020}, pages={417–423} }","ama":"Uhe B, Kuball C-M, Merklein M, Meschut G.

These techniques allow for the joining of dissimilar materials and thus enable multi-material design, while thermic joining methods reach their limits. Semi-tubular self-piercing riveting is an important mechanical joining technology. The rivet production, however, is costly and time-consuming, as the process consists of several process steps including the heat treatment and coating of the rivets in order to achieve an adequate strength and corrosion resistance. The use of high nitrogen steel as rivet material leads to the possibility of reducing process steps and hence increasing the efficiency of the process. However, the high tool loads being expected due to the high strain hardening of the material are a major challenge during the rivet production. Thus, there is a need for appropriate forming strategies, such as the manufacturing of the rivets at elevated temperatures. Prior investigations led to the conclusion that forming already at 200 °C results in a distinct reduction of the yield strength. To create a deeper understanding of the forming behaviour of high nitrogen steel at elevated temperatures, compression tests were conducted in a temperature range between room temperature and 200 °C. The determined true stress – true strain curves are the basis for the further process and tool design of the rivet production. Another key factor for the rivet manufacturing at elevated temperatures is the influence of the process temperature on the tribological conditions. For this reason, ring compression tests at room temperature and 200 °C are carried out. The friction factors are determined on the basis of calibration curves resulting from the numerical analysis of the ring compression process. The investigations indicate that the friction factor at 200 °C is significantly higher compared to room temperature. This essential fact has to be taken into account for the process and tool design for the rivet production using high nitrogen steel.","lang":"eng"}],"doi":"10.1016/j.jajp.2020.100023","series_title":"Journal of Advanced Joining Processes","language":[{"iso":"eng"}],"article_number":"100023","intvolume":"         1","date_updated":"2026-02-27T10:45:08Z","publication_status":"published","year":"2020","title":"Influence of the process temperature on the forming behaviour and the friction during bulk forming of high nitrogen steel","quality_controlled":"1","citation":{"apa":"Kuball, C.-M., Jung, R., Uhe, B., Meschut, G., &#38; Merklein, M.

Um diesem Problem in groß angelegten\r\nernährungsepidemiologischen Studien zu begegnen und LER zu identifizieren, wurden verschiedene statistische\r\n(Schätz-)Methoden entwickelt. Ziel der vorliegenden Studie war es, Misreporting zu identifizieren und LER hinsicht-\r\nlich ihrer soziodemografischen Merkmale zu beschreiben. Weiterhin sollte untersucht werden, ob bestimmte Le-\r\nbensmittelgruppen besonders von Low-energy-reporting betroffen sind und welchen Einfluss dies auf die Nähr-\r\nstoffzufuhr der Bevölkerung hat.\r\nMethoden: Datengrundlage bilden 943 Wiegeprotokolle der NVS II. Anhand verschiedener Schätzgleichungen\r\nwurden LER identifiziert. Unterschiede im Lebensmittelverzehr wurden absolut und adjustiert für die Energiezufuhr\r\nuntersucht. Die Nährstoffversorgung wurde mit den D-A-CH-Referenzwerten verglichen.\r\nErgebnisse: Die Prävalenz für Misreporting war abhängig von der angewandten Vorgehensweise zur Identifika-\r\ntion von Misreporting. Unter Verwendung des Goldberg-Cut-offs mit der Müller-Gleichung stieg die Wahrschein-\r\nlichkeit für Low-energy-reporting durch Übergewicht. Ebenso neigten eher Frauen und jüngere Personen aus der\r\nMittelschicht bzw. unteren Mittelschicht dazu, ihr Essverhalten nicht plausibel zu protokollierten. LER protokollierten\r\nim Verhältnis zur Energiezufuhr weniger Backwaren, Nüsse und Samen, Süßigkeiten, tierische Fette sowie Bier,\r\nWein und Sekt. LER hatten eine höhere Energiezufuhr aus Proteinen und absolut betrachtet war die Makro- und\r\nMikronährstoffzufuhr sowie die Ballaststoffzufuhr von LER signifikant kleiner. Nach Adjustierung für die protokol-\r\nlierte Energizufuhr war die Ernährung der LER (für die meisten Mikronährstoffe) allerdings nährstoffdichter. Der\r\nAnteil derer, die die D-A-CH-Referenzwerte für die verschiedenen Mikronährstoffe nicht erreichen, war unter den\r\nLER signifikant höher.\r\nFazit: Da in Studien zu Misreporting unterschiedliche Methoden zur Identifikation sowie zum Umgang mit LER\r\nangewandt werden, sind die Ergebnisse sind z. T. nicht konsistent. Dass Misreporting mit einem höheren Körper-\r\ngewicht assoziiert ist und, dass überproportional fett- und zuckerreiche Lebensmittel betroffen sind, wird durch viele\r\nStudien bestätigt. Ebenso zeigen mehrere Studien, dass es durch Low-energy-reporting zu einer Überschätzung\r\neiner nichtadäquaten Mikronährstoffzufuhr kommt. Für künftige Studien ist es sinnvoll einheitliche Standards zur\r\nIdentifikation von Misreporting, wie sie durch die EFSA formuliert werden, anzuwenden, die körperliche Aktivität\r\nobjektiv zu erfassen und vor allem Misreporting zu minimieren. Hierzu kann das Potential der Informations- und\r\nKommunikationstechnologie genutzt werden."}]},{"volume":8,"user_id":"64668","language":[{"iso":"eng"}],"_id":"64650","page":"146 - 154","main_file_link":[{"url":"https://www.ernaehrungs-umschau.de/print-artikel/13-08-2020-ernaehrungsbildung-in-allgemeinbildenden-schulen"}],"intvolume":"         8","article_type":"original","date_updated":"2026-03-03T12:36:22Z","author":[{"id":"64668","first_name":"Rhea","last_name":"Dankers","full_name":"Dankers, Rhea"},{"full_name":"Hirsch, Julia","last_name":"Hirsch","first_name":"Julia"},{"last_name":"Heseker","first_name":"Helmut","full_name":"Heseker, Helmut"}],"title":"Ernährungsbildung in allgemeinbildenden Schulen - eine Analyse der Rahmenvorgaben der Bundesländer für den fachbezogenen Unterricht","status":"public","year":"2020","type":"journal_article","date_created":"2026-02-26T08:04:55Z","abstract":[{"lang":"ger","text":"In der Studie „Ernährungsbezogene Bildungsarbeit in Kitas und Schulen“ wurde im Rahmen einer Dokumentenanalyse u. a. untersucht, inwiefern Ernährungsbildung in den Lehr- und Bildungsplänen der Bundesländer verankert und welcher Stundenumfang für die identifizierten Fächer mit Ernährungsbezug vorgesehen ist.
