This study introduces a 2D numerical model that circumvents direct contact modeling by applying a slip condition at the sheet interface, significantly reducing computational demands. A micro‐slip friction model is used to represent the mechanical interface behavior, while a two‐scale damage model captures the fatigue damage evolution.

This work presents a numerical uniform corrosion model that predicts the corrosion rate of hot-dip zinc in salt-spray environments by incorporating electrochemical reactions, mass transport via the Nernst–Planck equation, and ionic-strength effects through the Brønsted–Bjerrum relation. The model is calibrated using immersion-test data and extended to account for electrolyte layer growth, droplet deposition, and periodic run-off in salt-spray environments. The calibration establishes a relationship between the porosity of the zinc oxide layer and the rate constant of zinc oxide precipitation. The validated model reproduces the transition from activation- to diffusion-controlled corrosion and captures the experimentally observed corrosion kinetics with an error margin of 20% when electrolyte renewal is included. The results highlight the decisive role of electrolyte dynamics in salt-spray environments and provide a foundation for extending the framework to more complex cyclic corrosion tests."}],"user_id":"114741","project":[{"_id":"142","name":"TRR 285 - Subproject B03"},{"_id":"132","name":"TRR 285 - Project Area B"},{"name":"TRR 285: Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"_id":"64250","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2397-2106"]},"citation":{"ama":"Chen C, Hofmann M, Wallmersperger T.

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."}],"type":"conference","publication":"Materials Research Proceedings"},{"user_id":"104464","department":[{"_id":"630"}],"project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285: Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"_id":"140","name":"TRR 285 – B01: TRR 285 - Subproject B01"}],"_id":"59873","article_number":"01080","type":"conference","status":"public","author":[{"first_name":"Eugen","full_name":"Wolf, Eugen","last_name":"Wolf"},{"first_name":"Alexander","last_name":"Brosius","full_name":"Brosius, Alexander"}],"volume":408,"date_updated":"2025-06-23T07:25:21Z","conference":{"location":"Lisbon","end_date":"2025-06-05","start_date":"2025-06-01","name":"44th Conference of the International Deep Drawing Research Group"},"doi":"10.1051/matecconf/202540801080","publication_status":"published","publication_identifier":{"issn":["2261-236X"]},"citation":{"ama":"Wolf E, Brosius A.

These results offer valuable insights for the design of clinched joint assemblies, indicating that simplified joining strategies may suffice without compromising structural integrity under shear loading.","lang":"eng"}],"keyword":["Joining","Sheet Metal","Clinching"],"language":[{"iso":"eng"}]},{"citation":{"chicago":"Steinfelder, Christian, Clemens Acksteiner, and Alexander Brosius. “A New Joint with Versatile Properties Based on a Reuleaux Triangle Geometry.” CIRP Annals, 2025. https://doi.org/10.1016/j.cirp.2025.03.002.","ieee":"C.

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."}],"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","department":[{"_id":"630"}],"user_id":"104468","_id":"60285","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"}],"extern":"1","article_number":"01086","publication_identifier":{"issn":["2261-236X"]},"publication_status":"published","intvolume":" 408","citation":{"mla":"Lüder, Stephan, et al. “Investigation of the Impact of a Rotationally Superimposed Punch Stroke on the Binding Mechanisms of a Clinched Joint.” MATEC Web of Conferences, vol. 408, 01086, EDP Sciences, 2025, doi:10.1051/matecconf/202540801086.","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={10.1051/matecconf/202540801086}, 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.

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."}]},{"status":"public","type":"research_data","_id":"63764","project":[{"_id":"132","name":"TRR 285 - Project Area B"}],"department":[{"_id":"143"}],"user_id":"57245","year":"2025","citation":{"ieee":"D.

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."}],"date_created":"2024-06-18T07:00:26Z","author":[{"first_name":"C","last_name":"Zirngibl","full_name":"Zirngibl, C"},{"first_name":"S","last_name":"Goetz","full_name":"Goetz, S"},{"first_name":"S","full_name":"Wartzack, S","last_name":"Wartzack"}],"date_updated":"2024-06-18T07:06:38Z","publisher":"SAGE Publications","doi":"10.1177/09544089241259347","title":"Influence of process variations on clinch joint characteristics considering the effect of the nominal tool design","publication_status":"published","publication_identifier":{"issn":["0954-4089","2041-3009"]},"citation":{"ama":"Zirngibl C, Goetz S, Wartzack S.

These joints are usually weak spots. Here, corrosion and fatigue are decisive influencing factors for the assessment of the service life of such joints. Corrosion generally leads to material deterioration and thus to premature failure of the joints. Under certain circumstances, however, corrosion can lead to an increased fatigue life. While this effect has not yet been fully understood, the present work provides a possible explanation and a modeling approach to predict the fatigue life of precorroded clinched joints. The increased fatigue life is observed when the clinched components are briefly (up to 3 weeks) exposed to a salt spray environment. During this time, a small layer of corrosion products protrudes from the metal surface and fills the gaps between the joined sheets. Due to the increased contact area, the mechanical stress in the joint decreases, resulting in an improved fatigue performance. Although there are a variety of corrosion phenomena, for example, pitting, intergranular, and transgranular corrosion as well as galvanic corrosion, experimental studies indicate that galvanic corrosion is the main contributor of this effect. In the present work, a coupled electro‐chemo‐mechanical corrosion model is presented and applied to two test cases.

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"}],"status":"public","publisher":"Elsevier BV","date_updated":"2025-06-23T07:57:53Z","author":[{"full_name":"Steinfelder, Christian","last_name":"Steinfelder","first_name":"Christian"},{"last_name":"Rempel","full_name":"Rempel, Dennis","first_name":"Dennis"},{"first_name":"Alexander","last_name":"Brosius","full_name":"Brosius, Alexander"}],"date_created":"2025-06-23T07:54:23Z","volume":10,"title":"Influence of the material properties on the clinching process and the resulting load-bearing capacity of the joint","doi":"10.1016/j.jajp.2024.100263","publication_status":"published","publication_identifier":{"issn":["2666-3309"]},"year":"2024","citation":{"ama":"Steinfelder C, Rempel D, Brosius A.
