In der vorliegenden Arbeit wird die Zuverlässigkeit von gefügten Proben mit einer Mehrfachanordnung von Clinchpunkten unter zyklischer Beanspruchung untersucht. Ziel ist es, die Wechselwirkung benachbarter Clinchpunkte und deren Einfluss auf die Ermüdungslebensdauer zu untersuchen. Dazu wurden Proben mit variierenden Fügepunktabständen hergestellt und in Versuchsreihen zyklisch belastet. Die Resultate zeigen, dass die räumliche Anordnung der Clinchpunkte das Ermüdungsverhalten beeinflusst. Es wurde festgestellt, dass bei Mehrfachanordnungen sowohl der Fügepunktabstand als auch der Abstand der Fügepunkte zum Bauteilrand in Belastungsrichtung einen Einflussfaktor darstellen. Die vorliegende Arbeit leistet somit einen Beitrag zur Lebensdauervorhersage gefügter Strukturen und bildet eine Grundlage für weiterführende Untersuchungen zu Gestaltungsempfehlungen.","lang":"ger"}],"publication":"43.

The growing significance of lightweight design, reveals drawbacks of conventional joining processes such as welding, which are known to consume a considerable amount of energy. This fosters the use of mechanical joining processes including clinching. However, the lack of universally applicable design methods results in a cost- and time-intensive design process. The utilization of machine learning methods can overcome these drawbacks. To ensure a reliable clinch joint design, inherent uncertainties of the design parameter such as tool deviations need to be considered in the design process. Varying distributions of design parameters, due to changes in the manufacturing process, can lead to high-computational effort in recalculating the resulting clinch joint properties with numerical simulations. Current metamodel-based methods for consideration of inherent uncertainties within the design parameters do not investigate the transferability of metamodels to different distributions of design parameters, which can lead to incorrect predictions. Therefore, this contribution investigates the performance of several metamodels on differently distributed design parameters. The obtained results indicate that metamodels demonstrate the best performance when training and evaluation distributions are identical and that polynomial regression models perform best on disparate distributions, when trained on uniform distributions.</jats:p>"}],"_id":"60198","language":[{"iso":"eng"}],"publisher":"Materials Research Forum LLC","volume":52,"user_id":"107109","doi":"10.21741/9781644903551-35","author":[{"full_name":"Einwag, Jonathan-Markus","first_name":"Jonathan-Markus","last_name":"Einwag"},{"full_name":"Mayer, Yannik","last_name":"Mayer","first_name":"Yannik"},{"full_name":"Goetz, Stefan","last_name":"Goetz","first_name":"Stefan"},{"first_name":"Sandro","last_name":"Wartzack","full_name":"Wartzack, Sandro"}],"publication_identifier":{"issn":["2474-395X"]},"status":"public","year":"2025","title":"Impact of the parameter distribution on the predictive quality of metamodels for clinch joint properties","intvolume":"        52","publication_status":"published","date_updated":"2025-06-12T15:06:41Z"},{"date_created":"2025-05-13T05:41:58Z","keyword":["Joining","Sheet Metal","Stiffness","Clinching"],"type":"conference","department":[{"_id":"630"}],"publication":"MATEC Web of Conferences","abstract":[{"text":"This paper focuses on the failure behavior of clinched specimens with various stiffnesses under shear tensile loading.

At the same time, various industries are increasingly trending towards multi-material systems consisting of parts with varying geometric and mechanical properties. Due to the varying properties, rigid mechanical joining processes require sampling procedures and periodic changes of tool components or auxiliary joining parts. Consequently, research is focusing on versatile mechanical joining processes that allow increased control by modifying the process parameters. Two processes based on self-piercing riveting can achieve a significant increase in process influence possibilities through a multi-linear actuator as versatile self-piercing riveting (V-SPR) and a tumbling superimposed actuator as tumbling self-piercing riveting (T-SPR). Initial research into V-SPR has shown that this process can be used to achieve a higher variation in overall package thickness by adapting the rivet geometry and using multiple linear actuators. The T-SPR process also enables increased material flow control by means of targeted compression of the rivet using the tumbling actuator, thereby extending the range of joints that can be manufactured. Based on these two processes, a combination of the two mechanisms of action is to be developed.","lang":"eng"}],"date_created":"2025-06-27T08:27:42Z","type":"journal_article","department":[{"_id":"43"},{"_id":"157"}],"title":"Integration of multiple-linear and tumbling kinematics into self-piercing riveting","year":"2025","publication_identifier":{"issn":["2261-236X"]},"author":[{"id":"44935","full_name":"Holtkamp, Pia Katharina","last_name":"Holtkamp","first_name":"Pia Katharina"},{"id":"83423","first_name":"Simon","last_name":"Wituschek","full_name":"Wituschek, Simon"},{"first_name":"Michael","last_name":"Lechner","full_name":"Lechner, Michael"},{"id":"32056","orcid":"0000-0002-2763-1246","last_name":"Meschut","first_name":"Gerson","full_name":"Meschut, Gerson"}],"date_updated":"2025-06-27T08:34:46Z","publication_status":"published","intvolume":"       408","article_number":"01069","language":[{"iso":"eng"}],"doi":"10.1051/matecconf/202540801069"},{"quality_controlled":"1","project":[{"name":"TRR 285: TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130","grant_number":"418701707"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C01: TRR 285 - Subproject C01","_id":"145"},{"name":"TRR 285 – C03: TRR 285 - Subproject C03","_id":"147"},{"name":"TRR 285 – C02: TRR 285 - Subproject C02","_id":"146"},{"name":"TRR 285 – C05: TRR 285 - Subproject C05","_id":"149"}],"citation":{"ieee":"M.

The DFG-funded Collaborative Research Center TRR 285 is exploring XCT's application in assessing mechanical joinability across various joining processes and materials, particularly in multi-material systems like steel-aluminum joints. XCT faces challenges in accurately capturing multi-material compositions, leading to artifacts that complicate interface detection.

Simplified models are used to model the joints in finite element simulations, allowing for efficient yet accurate analysis of the load distribution and structural response under varying joint orientations. Variations in joint orientation result in measurable changes in the distribution of forces on adjacent joints, influencing their behavior and that of the overall assembly.

The scale spanning heterogeneity of their material structure and its influence on the material behavior, however, presents significant challenges for most joining technologies, such as self-piercing riveting (SPR). During mechanical joining, the material structure is significantly altered within and around the joining zone, heavily influencing the material behavior. A comprehensive understanding of the underlying phenomena of material alteration during the SPR process is essential as basis for validating numerical simulations. This study examines the material structure at ten stages of a step-setting test of SPR with two FRTP sheets with glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage phenomena within different areas of the setting test are analyzed three-dimensionally and key parameters are quantified. Dominating phenomena during the penetration of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF) and fiber bending, while delamination, fiber kinking and roving splitting are also observed. At the final stages, the bottom layers of the second sheet collapse and form a bulge into the cavity of the die.","lang":"eng"}],"publication":"Proceedings of the 8th International Conference on Integrity-Reliability-Failure (IRF2025)","type":"conference","keyword":["self-piercing riveting","computed tomography","thermoplastic composites","process-structure-interaction"],"date_created":"2025-09-08T11:52:45Z"},{"has_accepted_license":"1","status":"public","conference":{"end_date":"2024-07-05","location":"Porto, Portugal","name":"5th International Conference on Materials Design and Applications 2024","start_date":"2024-07-04"},"user_id":"7850","_id":"58807","publisher":"Sage Publications","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"},{"name":"TRR 285 – C02: TRR 285 - Subproject C02","_id":"146"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"short":"M.

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."}],"publication":"The Journal of Materials: Design and Applications, Part L","keyword":["aluminium","casting","microstructure","joinability","self-piercing riveting"],"type":"journal_article","department":[{"_id":"43"},{"_id":"158"},{"_id":"157"},{"_id":"9"},{"_id":"321"}],"date_created":"2025-02-24T10:25:31Z"},{"intvolume":"        52","date_updated":"2026-05-12T12:12:36Z","publication_status":"published","author":[{"full_name":"Lüder, Stephan","last_name":"Lüder","first_name":"Stephan"},{"id":"44935","last_name":"Holtkamp","first_name":"Pia Katharina","full_name":"Holtkamp, Pia Katharina"},{"full_name":"Wituschek, Simon","first_name":"Simon","last_name":"Wituschek"},{"full_name":"Bobbert, Mathias","last_name":"Bobbert","first_name":"Mathias","id":"7850"},{"full_name":"Meschut, Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","first_name":"Gerson","id":"32056"},{"full_name":"Lechner, Michael","last_name":"Lechner","first_name":"Michael"},{"last_name":"Schmale","first_name":"Hans Christian","full_name":"Schmale, Hans Christian"}],"publication_identifier":{"issn":["2474-395X"]},"year":"2025","title":"Analysis of the binding mechanisms depending on versatile process variants of self-piercing riveting","doi":"10.21741/9781644903551-13","series_title":"Sheet Metal 2025","language":[{"iso":"eng"}],"abstract":[{"text":"The constantly increasing demand for climate protection and resource conservation requires innovative and versatile joining processes that improve adaptability to the joining task and robustness to enable flexible manufacturing on a production line.

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.","lang":"eng"}],"issue":"1","publication":"Applied Sciences","type":"journal_article","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"date_created":"2026-01-20T08:47:40Z","publication_status":"published","date_updated":"2026-05-12T12:46:22Z","intvolume":"        16","year":"2025","title":"Validation and Verification of Novel Three-Dimensional Crack Growth Simulation Software GmshCrack3D","publication_identifier":{"issn":["2076-3417"]},"author":[{"last_name":"Krome","first_name":"Sven","full_name":"Krome, Sven","id":"57245"},{"last_name":"Duffe","first_name":"Tobias","full_name":"Duffe, Tobias","id":"41322"},{"last_name":"Kullmer","first_name":"Gunter","full_name":"Kullmer, Gunter","id":"291"},{"full_name":"Schramm, Britta","last_name":"Schramm","first_name":"Britta","id":"4668"},{"id":"106876","first_name":"Richard","last_name":"Ostwald","orcid":"0000-0003-2147-8444","full_name":"Ostwald, Richard"}],"doi":"10.3390/app16010384","article_number":"384","language":[{"iso":"eng"}],"quality_controlled":"1","project":[{"_id":"132","name":"TRR 285 - Project Area B"},{"name":"TRR 285 - Subproject B04","_id":"143"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"apa":"Krome, S., Duffe, T., Kullmer, G., Schramm, B., &#38; Ostwald, R.

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"}],"extern":"1","publication":"MATEC Web of Conferences","department":[{"_id":"630"}],"type":"conference","keyword":["Joining","Sheet Metal","Tribology","Clinching"],"date_created":"2025-06-20T06:57:16Z","intvolume":"       408","date_updated":"2026-05-12T13:08:56Z","publication_status":"published","author":[{"first_name":"Stephan","last_name":"Lüder","full_name":"Lüder, Stephan"},{"last_name":"Wolf","first_name":"Eugen","full_name":"Wolf, Eugen"},{"full_name":"Schmale, Hans Christian","last_name":"Schmale","first_name":"Hans Christian"},{"full_name":"Brosius, Alexander","first_name":"Alexander","last_name":"Brosius"}],"publication_identifier":{"issn":["2261-236X"]},"year":"2025","title":"Investigation of the impact of a rotationally superimposed punch stroke on the binding mechanisms of a clinched joint","doi":"10.1051/matecconf/202540801086","language":[{"iso":"eng"}],"article_number":"01086","project":[{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"name":"TRR 285 – A04: TRR 285 - Subproject A04","_id":"138"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B01: TRR 285 - Subproject B01","_id":"140"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"quality_controlled":"1","citation":{"short":"S.

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>","lang":"eng"}],"date_created":"2025-05-13T06:54:20Z","type":"conference","department":[{"_id":"157"}],"year":"2025","title":"Experimental and numerical investigation of the influence of rolling-induced sheet metal deformation on SPR joints","publication_identifier":{"issn":["2474-395X"]},"author":[{"last_name":"Schlichter","first_name":"Malte Christian","full_name":"Schlichter, Malte Christian","id":"61977"},{"full_name":"Harabati, Özcan","last_name":"Harabati","first_name":"Özcan"},{"id":"76631","last_name":"Ludwig","first_name":"Jean-Patrick","full_name":"Ludwig, Jean-Patrick"},{"full_name":"Böhnke, Max","first_name":"Max","last_name":"Böhnke","id":"45779"},{"full_name":"Bielak, Christian Roman","first_name":"Christian Roman","last_name":"Bielak","id":"34782"},{"id":"7850","full_name":"Bobbert, Mathias","first_name":"Mathias","last_name":"Bobbert"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","first_name":"Gerson","orcid":"0000-0002-2763-1246"}],"publication_status":"published","date_updated":"2026-05-13T13:50:44Z","intvolume":"        54","language":[{"iso":"eng"}],"doi":"10.21741/9781644903599-148"},{"department":[{"_id":"143"},{"_id":"630"}],"type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"date_created":"2024-02-22T09:35:01Z","publication":"Engineering Fracture Mechanics","doi":"10.1016/j.engfracmech.2023.109826","language":[{"iso":"eng"}],"article_number":"109826","intvolume":"       296","publication_status":"published","date_updated":"2024-02-22T09:55:31Z","author":[{"first_name":"Gunter","last_name":"Kullmer","full_name":"Kullmer, Gunter","id":"291"},{"id":"45673","full_name":"Weiß, Deborah","first_name":"Deborah","last_name":"Weiß"},{"id":"4668","full_name":"Schramm, Britta","first_name":"Britta","last_name":"Schramm"}],"publication_identifier":{"issn":["0013-7944"]},"year":"2024","title":"An alternative and robust formulation of the fatigue crack growth rate curve for long cracks","project":[{"name":"TRR 285: TRR 285","_id":"130","grant_number":"418701707"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"name":"TRR 285 – B04: TRR 285 - Subproject B04","_id":"143"}],"citation":{"mla":"Kullmer, Gunter, et al. “An Alternative and Robust Formulation of the Fatigue Crack Growth Rate Curve for Long Cracks.” <i>Engineering Fracture Mechanics</i>, vol. 296, 109826, Elsevier BV, 2024, doi:<a href=\"https://doi.org/10.1016/j.engfracmech.2023.109826\">10.1016/j.engfracmech.2023.109826</a>.","ama":"Kullmer G, Weiß D, Schramm B.

In this context, mechanical joining technology clinching offers a fast and energy-efficient procedure for assembling sheet metals, being a proper alternative to established joining methods, such as spot welding. However, the design of clinch points is a challenge, which is partly supported by numerical or data-based approaches for optimal tool dimensions assuring proper joint characteristics. While this is usually done for an ideal environment, real joining processes are characterized by multiple inevitably varying parameters, e.g. of the material, which have a significant impact on the quality of clinch points. Therefore, this contribution addresses the current gap by analyzing the effect of parameter variations or uncertainties on the resulting joint characteristics and studying the impact of the nominal tool design. Thus, an efficient meta-model-based variation simulation procedure is proposed and used for analyzing the effect of different tool design configurations and variation scenarios. Based on the results, it was found that varying process parameters have a strong impact on the resulting joint characteristics, whereby the effect significantly depends on the nominal tool design. This reveals the potential for a robust tool design and implies that the nominal tool design and the tolerancing of parameters should be done simultaneously for a reliable virtual joining point design without extensive iterations and physical tests.","lang":"eng"}],"date_created":"2024-06-18T07:00:26Z","department":[{"_id":"630"}],"type":"journal_article","publication_identifier":{"issn":["0954-4089","2041-3009"]},"author":[{"last_name":"Zirngibl","first_name":"C","full_name":"Zirngibl, C"},{"full_name":"Goetz, S","last_name":"Goetz","first_name":"S"},{"full_name":"Wartzack, S","last_name":"Wartzack","first_name":"S"}],"title":"Influence of process variations on clinch joint characteristics considering the effect of the nominal tool design","year":"2024","status":"public","date_updated":"2024-06-18T07:06:38Z","publication_status":"published","_id":"54797","publisher":"SAGE Publications","language":[{"iso":"eng"}],"doi":"10.1177/09544089241259347","user_id":"107109"}]
