To tackle this challenge, on the one hand, modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight design offers various possibilities. Multi-Material Design (MMD) involves designing car\r\nbodies that combine different materials that require joining. Given the variety of materials, mechanical joining\r\nprocesses are preferred. Especially the current development of the Giga/Mega-casting process concerning\r\naluminium casting and the subsequent mechanical joining illustrates the challenges of this material group. In car\r\nproduction, aluminium castings are mainly made from aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient ductility leads to crack initiation during mechanical joining. Cast parts are therefore often\r\nused in areas of the car body that are exposed to high-pressure loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure through tailored solidification rates and a developed heat-treatment chain strategy adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical, and joining properties are used to develop a\r\nsolidification-joining correlation for the SPR process across a range of Si contents and solidification rates. The\r\npurpose is to develop the ability to produce suitable aluminium castings with sufficient joinability, thereby\r\nimproving versatility.","lang":"eng"}],"publisher":"Elsevier","date_created":"2026-02-26T11:21:24Z","title":"Solidification-joinability correlation of hypoeutectic aluminium casting alloys for self-piercing riveting (SPR)","quality_controlled":"1","year":"2026"},{"page":"293-300","intvolume":"        52","citation":{"mla":"Reschke, Gregor, and Alexander Brosius. “Transient Dynamic Analysis: Performance Evaluation of Tactile Measurement.” <i>Materials Research Proceedings</i>, vol. 52, Materials Research Forum LLC, 2025, pp. 293–300, doi:<a href=\"https://doi.org/10.21741/9781644903551-36\">10.21741/9781644903551-36</a>.","short":"G.

The assessment of mechanically joined connections, such as clinched connections, is usually conducted destructively. Applicable non-destructive testing methods like computed tomography are time-consuming and costly, or, like electrical resistance measurement, provide only a limited amount of information. A fast, non-destructive evaluation of the joints condition shall be made possible by using transient dynamic analysis (TDA). It is based on the introduction of sound waves and the evaluation of the response behavior after passing through the structure. This study focuses the application of TDA to clinched shear connections to evaluate the performance of the tactile measuring setup. Twenty-one series were investigated, covering variations in joining task, manufacturing and defect. The evaluation was carried out using machine learning to determine for which series characteristic signals may be detected. It was shown that a classification of the investigated specimens is possible, whereby the classification accuracy depends on the examined variation. Furthermore, the accuracy was evaluated as a function of frequency and results were concluded to identify the limits of the used measuring setup.</jats:p>","lang":"eng"}],"publication":"Materials Research Proceedings","language":[{"iso":"eng"}],"keyword":["Joining","Machine Learning","Transient Dynamic Analysis"]},{"keyword":["Joining","Casting","Self-pierce riveting","Aluminium casting alloy"],"language":[{"iso":"eng"}],"abstract":[{"text":"Lightweight design is a driving concept in modern automotive engineering to minimize resource consumption over a vehicle's lifecycle through multi-material design, which relies on the use of joining techniques in car body fabrication. Multi-material design and the increasing trend towards producing large structural components using the megacasting process pose considerable challenges, particularly in the mechanical joining of aluminium-silicon (AlSi) castings. These castings typically exhibit low ductility and are prone to cracking when mechanically joined. Based on the excellent castability of hypoeutectic AlSi alloys, these are applied in sand casting and die casting as well as in megacasting. With a silicon content between 7 wt% and 12 wt%, these AlSi-alloys have a plate-like silicon phase that initiates cracks during mechanical joining. To enhance the joinability of castings, the research hypothesis is that improved solidification conditions enable a significant modification in the microstructure and therefore, increase the mechanical properties. During the manufacture of the castings using the sand casting process, the solidification conditions within the structural elements are varied to modify the microstructure to obtain castings with graded microstructure. The castings are evaluated using mechanical, microstructural and joining testing methods and finally, a microstructure-joinability correlation is established.","lang":"eng"}],"publication":"44th Conference of the International Deep Drawing Research Group (IDDRG 2025)","title":"Mechanical joinability of microstructurally graded structural components manufactured from hypoeutectic aluminium casting alloys","date_created":"2025-05-12T15:21:06Z","year":"2025","quality_controlled":"1","article_number":"01081","article_type":"original","project":[{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"_id":"136","name":"TRR 285 – A02: TRR 285 - Subproject A02"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"_id":"59872","user_id":"7850","department":[{"_id":"43"},{"_id":"158"},{"_id":"157"},{"_id":"9"},{"_id":"321"}],"status":"public","type":"journal_article","main_file_link":[{"url":"\thttps://doi.org/10.1051/matecconf/202540801081","open_access":"1"}],"doi":"10.1051/matecconf/202540801081","conference":{"end_date":"2025-06-05","location":"Lissabon (Portugal)","name":"44th Conference of the International Deep Drawing Research Group (IDDRG 2025)","start_date":"2025-06-02"},"oa":"1","date_updated":"2026-02-24T13:41:58Z","author":[{"first_name":"Moritz","last_name":"Neuser","id":"32340","full_name":"Neuser, Moritz"},{"last_name":"Schlichter","id":"61977","full_name":"Schlichter, Malte Christian","first_name":"Malte Christian"},{"last_name":"Hoyer","full_name":"Hoyer, Kay-Peter","id":"48411","first_name":"Kay-Peter"},{"first_name":"Mathias","last_name":"Bobbert","id":"7850","full_name":"Bobbert, Mathias"},{"id":"32056","full_name":"Meschut, Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","first_name":"Gerson"},{"first_name":"Mirko","last_name":"Schaper","id":"43720","full_name":"Schaper, Mirko"}],"volume":408,"citation":{"bibtex":"@article{Neuser_Schlichter_Hoyer_Bobbert_Meschut_Schaper_2025, title={Mechanical joinability of microstructurally graded structural components manufactured from hypoeutectic aluminium casting alloys}, volume={408}, DOI={<a href=\"https://doi.org/10.1051/matecconf/202540801081\">10.1051/matecconf/202540801081</a>}, number={01081}, journal={44th Conference of the International Deep Drawing Research Group (IDDRG 2025)}, author={Neuser, Moritz and Schlichter, Malte Christian and Hoyer, Kay-Peter and Bobbert, Mathias and Meschut, Gerson and Schaper, Mirko}, year={2025} }","mla":"Neuser, Moritz, et al. “Mechanical Joinability of Microstructurally Graded Structural Components Manufactured from Hypoeutectic Aluminium Casting Alloys.” <i>44th Conference of the International Deep Drawing Research Group (IDDRG 2025)</i>, vol. 408, 01081, 2025, doi:<a href=\"https://doi.org/10.1051/matecconf/202540801081\">10.1051/matecconf/202540801081</a>.","short":"M.

As part of the development of a method for ensuring the versatility of clinching, an additional rotational movement of the punch was introduced as a control variable to influence friction in the mechanical joining process. The effect of rotational superimposition on the force-displacement curve of the clinching processes was investigated using four test variants with different kinematics. The primary objective was to evaluate the binding mechanisms that maintain the integrity of the clinched joint. To evaluate the force closure of the resulting joint, two testing methods were employed throughout the course of the research, non-destructive resistance measurement using four-wire sensing method and destructive torsion testing. A crucial factor influencing the efficacy of the process is surface cleanliness, as contaminants between joining partners can impede the effectiveness of the clinched joint. Therefore, all specimens were meticulously cleaned prior to experimentation. This method exhibits promising potential in creating clinched joints that align with the demands of flexible manufacturing environments.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Joining","Sheet Metal","Tribology","Clinching"],"quality_controlled":"1","year":"2025","date_created":"2025-06-20T06:57:16Z","publisher":"EDP Sciences","title":"Investigation of the impact of a rotationally superimposed punch stroke on the binding mechanisms of a clinched joint","type":"conference","status":"public","user_id":"104468","department":[{"_id":"630"}],"project":[{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"name":"TRR 285 – A04: TRR 285 - Subproject A04","_id":"138"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"name":"TRR 285 – B01: TRR 285 - Subproject B01","_id":"140"}],"_id":"60285","extern":"1","article_number":"01086","publication_status":"published","publication_identifier":{"issn":["2261-236X"]},"citation":{"mla":"Lüder, Stephan, et al. “Investigation of the Impact of a Rotationally Superimposed Punch Stroke on the Binding Mechanisms of a Clinched Joint.” <i>MATEC Web of Conferences</i>, vol. 408, 01086, EDP Sciences, 2025, doi:<a href=\"https://doi.org/10.1051/matecconf/202540801086\">10.1051/matecconf/202540801086</a>.","bibtex":"@inproceedings{Lüder_Wolf_Schmale_Brosius_2025, title={Investigation of the impact of a rotationally superimposed punch stroke on the binding mechanisms of a clinched joint}, volume={408}, DOI={<a href=\"https://doi.org/10.1051/matecconf/202540801086\">10.1051/matecconf/202540801086</a>}, number={01086}, booktitle={MATEC Web of Conferences}, publisher={EDP Sciences}, author={Lüder, Stephan and Wolf, Eugen and Schmale, Hans Christian and Brosius, Alexander}, year={2025} }","short":"S.

This study presents a comparative analysis of two physically based debonding methods: the established hot-air process and a cryogenic cold process based on liquid nitrogen (LN2). The primary objective is to assess the ecological impact and process-related sustainability of both approaches.\r\nExperimental investigations were conducted on a component-representative triple-sheet structure that simulates common automotive flange joints. Thermal input was applied either by convective heating using a hot air gun or by direct cooling through a contact-based LN2 tool. The resulting temperature profiles were recorded using spatially distributed thermocouples. Subsequently, the outer panel was selectively debonded to replicate a repair scenario, and the mechanical integrity of the remaining adhesive joint was evaluated through Mode I testing of L-shaped specimens. Process data served as input for an Life Cycle Assessment (LCA) according to DIN EN ISO 14040.\r\nThe cryogenic method achieved a 40% reduction in carbon footprint compared to the hot-air process (0.337 kg vs. 0.559 kg CO2-equivalents), primarily due to its shorter process time and more efficient heat transfer. While the hot-air method’s impact is mainly driven by electrical energy use, that of the cold method stems from cryogenic media consumption. Notwithstanding certain disadvantages in specific impact categories, the LN2-based process exhibits a superior overall ecological performance and signifies a promising solution for repair- and recycling-oriented adhesive separation in structural vehicle applications.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Sustainable debonding","Structural adhesives","Sustainable joining technologies","Life Cycle Assessment (LCA)","Automotive repair process","Economically efficient debonding"],"publication_status":"published","publication_identifier":{"issn":["2666-3309"]},"citation":{"bibtex":"@article{Jordan_Hermelingmeier_Gilich_Meschut_De Santis_Schlüter_2025, title={Comparison of the economic efficiency and sustainability of two debonding processes for structurally bonded sills}, volume={12}, DOI={<a href=\"https://doi.org/10.1016/j.jajp.2025.100332\">10.1016/j.jajp.2025.100332</a>}, number={100332}, journal={Journal of Advanced Joining Processes}, publisher={Elsevier}, author={Jordan, Alex and Hermelingmeier, Lucas and Gilich, Julian and Meschut, Gerson and De Santis, Marco Sebastian and Schlüter, Alexander}, year={2025} }","mla":"Jordan, Alex, et al. “Comparison of the Economic Efficiency and Sustainability of Two Debonding Processes for Structurally Bonded Sills.” <i>Journal of Advanced Joining Processes</i>, vol. 12, 100332, Elsevier, 2025, doi:<a href=\"https://doi.org/10.1016/j.jajp.2025.100332\">10.1016/j.jajp.2025.100332</a>.","short":"A.

For this purpose, three series of tests were performed. In the first series of tests, the influence of heat treatment up to 340 °C on the mechanical properties of an age-hardenable AlMgSi alloy was investigated. Holding time and temperature were varied and the material strength was evaluated by tensile and hardness tests. Two strength-increasing and two strength-reducing heat treatment parameters were identified. In the second series of tests, selected heat treatment parameters were applied to a larger number of specimens and the joint strength was investigated by shear and head tensile tests. In the shear tensile test, mainly the properties of the punch-side material have an influence on the resulting joint strength. A change in strength of the die-side material can be neglected. In contrast, the properties of both sheets are important in the head tensile test. The strength of the joint will only increase if the strength of both sheets is increased. In general, a strength increasing heat treatment resulted in higher joint strength. In the third series of tests, the factor of punch displacement was considered, which was demonstrated to directly influence the formation of the clinched joint geometry.","lang":"eng"}],"publication":"Journal of Advanced Joining Processes","type":"journal_article","language":[{"iso":"eng"}],"keyword":["Joining by forming","Clinching","EN AW-6014","Heat treatment","Load-bearing capacity"],"article_number":"100263","department":[{"_id":"630"}],"user_id":"104464","_id":"60300","project":[{"name":"TRR 285: TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130","grant_number":"418701707"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B01: TRR 285 - Subproject B01","_id":"140"}],"intvolume":"        10","citation":{"ama":"Steinfelder C, Rempel D, Brosius A.

In this context, mechanical joining technologies, such as clinching, are becoming more and more relevant especially in the automotive industry. However, the availability of only few standards and almost none systematic design methods causes a still very time- and cost-intensive assembly development process considering mainly expert knowledge and a considerable amount of experimental studies. Motivated by this, the presented work introduces a novel approach for the methodical design and dimensioning of mechanically clinched assemblies. Therefore, the utilization of regression models, such as machine learning algorithms, combined with manufacturing knowledge ensures a reliable estimation of individual clinched joint characteristics. In addition, the implementation of an engineering workbench enables the following data-driven and knowledge-based generation of high-quality initial assembly designs already in early product development phases. In a subsequent analysis and adjustment, these designs are being improved while guaranteeing joining safety and loading conformity. The presented results indicate that the methodological approach can pave the way to a more systematic design process of mechanical joining assemblies, which can significantly shorten the required number of iteration loops and therefore the product development time.","lang":"eng"}],"status":"public","publication":"Materials Research Proceedings","type":"conference","title":"Methodical approach for the design and dimensioning of mechanical clinched assemblies","conference":{"name":"20th International Conference on Sheet Metal","start_date":"2023-04-02","end_date":"2023-04-05","location":"Erlangen-Nürnberg"},"doi":"10.21741/9781644902417-23","publisher":"Materials Research Forum LLC","date_updated":"2025-06-23T08:15:07Z","volume":25,"author":[{"first_name":"Christoph","full_name":"Zirngibl, Christoph","last_name":"Zirngibl"},{"first_name":"Sven","last_name":"Martin","full_name":"Martin, Sven"},{"last_name":"Steinfelder","full_name":"Steinfelder, Christian","first_name":"Christian"},{"full_name":"Schleich, Benjamin","last_name":"Schleich","first_name":"Benjamin"},{"first_name":"Thomas","full_name":"Tröster, Thomas","last_name":"Tröster"},{"last_name":"Brosius","full_name":"Brosius, Alexander","first_name":"Alexander"},{"first_name":"Sandro","full_name":"Wartzack, Sandro","last_name":"Wartzack"}],"date_created":"2025-06-23T08:08:23Z","year":"2023","intvolume":"        25","citation":{"bibtex":"@inproceedings{Zirngibl_Martin_Steinfelder_Schleich_Tröster_Brosius_Wartzack_2023, title={Methodical approach for the design and dimensioning of mechanical clinched assemblies}, volume={25}, DOI={<a href=\"https://doi.org/10.21741/9781644902417-23\">10.21741/9781644902417-23</a>}, booktitle={Materials Research Proceedings}, publisher={Materials Research Forum LLC}, author={Zirngibl, Christoph and Martin, Sven and Steinfelder, Christian and Schleich, Benjamin and Tröster, Thomas and Brosius, Alexander and Wartzack, Sandro}, year={2023} }","short":"C.

The cause and effect relationships between the joint and the joint environment offers the possibility of a specific modification through an adaptation in the design process. In order to identify these cause and effect relationships and resulting interactions experimentally, numerous of experiments are required. In this publication, a concept for the automated manufacturing of head tensile test and shear tensile test specimens – from cutting to clinching – by using a punch laser machine is presented. Based on a full-factorial experimental design, the parameters change of the properties of the joint environment by beading and change of the punch displacement are addressed. The influence on the properties of the clinched specimen is evaluated based on the variables Stiffness, force at the beginning of yielding and maximum force at head tensile loading and shear tensile loading. In addition, the geometric quality parameters of neck thickness, interlock and bottom thickness are evaluated. The relationships can be used to apply uniform loads to joints in joined structures to counteract oversizing.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Sheet Metal","Joining","Stiffness"],"year":"2023","date_created":"2025-06-23T08:00:55Z","publisher":"Materials Research Forum LLC","title":"Experimental investigation of the cause and effect relationships between the joint and the component during clinching","type":"conference","status":"public","user_id":"104464","department":[{"_id":"630"}],"project":[{"grant_number":"418701707","name":"TRR 285: TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B01: TRR 285 - Subproject B01","_id":"140"}],"_id":"60302","publication_status":"published","publication_identifier":{"issn":["2474-395X"]},"citation":{"apa":"Steinfelder, C., &#38; Brosius, A.

Conventional rivets for self-piercing riveting differ in their geometry, the material used, the condition of the material and the coating. To shorten the manufacturing process, the use of stainless steel with high strain hardening as the rivet material represents a promising approach. This allows the coating of the rivets to be omitted due to the corrosion resistance of the material and, since the strength of the stainless steel is achieved by cold forming, heat treatment is no longer required. In addition, it is possible to adjust the local strength within the rivet. Because of that, the authors have elaborated a concept for using high nitrogen steel 1.3815 as the rivet material. The present investigation focusses on the joint strength in order to evaluate the capability of rivets in high nitrogen steel by comparison to conventional rivets made of treatable steel. Due to certain challenges in the forming process of the high nitrogen steel rivets, deviations result from the targeted rivet geometry. Mainly these deviations cause a lower joint strength with these rivets, which is, however, adequate. All in all, the capability of the new rivet is proven by the results of this investigation.

Self-piercing riveting (SPR) is an important mechanical joining technique for multi-material structures. Rivets for SPR are coated to prevent corrosion, but this coating also influences the friction that prevails during the joining process. The aim of the present investigation is to evaluate this influence. The investigation focuses on the common rivet coatings Almac® and zinc-nickel with topcoat as well as on uncoated rivet surfaces. First of all, the coating thickness and the uniformity of the coating distribution are analysed. Friction tests facilitate the classification of the surface properties. The influence of the friction on the characteristic joint parameters and the force-stroke curves is analysed by means of experimental joining tests. More in-depth knowledge of the effects that occur is achieved through the use of numerical simulation. Overall, it is shown that the surface condition of the rivet has an impact on the friction during the joining process and on the resulting joint. However, the detected deviations between different surface conditions do not restrict the operational capability of SPR and the properties of uncoated rivet surfaces, in particular, are similar to those of Almac®-coated rivets. It can thus be assumed that SPR with respect to the joining process is also possible without rivet coating in principle."}],"status":"public","_id":"22272","user_id":"53912","department":[{"_id":"157"}],"keyword":["Coating","Friction","Joining"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2021","citation":{"ama":"Uhe B, Kuball C-M, Merklein M, Meschut G.

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.","lang":"eng"}],"type":"conference_editor","doi":"10.1016/j.promfg.2020.08.052","title":"Process design for the forming of semi-tubular self-piercing rivets made of high nitrogen steel","volume":50,"date_created":"2020-10-12T08:30:08Z","date_updated":"2026-02-27T10:43:48Z","intvolume":"        50","page":"280-285","citation":{"apa":"Kuball, C.-M., Uhe, B., Meschut, G., &#38; Merklein, M.

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."}],"status":"public"}]
