Consequently, the future over dimensioning can be reduced. Furthermore, the improved prediction quality of the joining process simulation leads to an improvement in the simulation of load-bearing capacity as well. In this way, the entire sampling process can be performed virtually without any experimental investigations. This will contribute to the advancement of lightweight construction in the automotive industry. In this work, the frictional behavior is studied in dependence on the local joining process parameters. As a reference for the numerical investigations, clinch joints by means of a die with fixed geometry are joined. Additionally, a hardness mapping is performed on the microsection of the clinch joints. It shows the local strain hardening, which correlates with the forming degree in the simulation. Based on the occurring contacts and the local joining process parameters in the joining process simulation, the test matrix for the experimental friction tests is defined. The friction tests are carried out on a compression-torsion-tribometer. This type of tribometer is able to apply high interface pressures above the initial yield stress due to the specimen encapsulation. Besides, the pure joining part contact, the contact between the joining part and joining tool can be tested as well. The experimental test setup offers the possibility to evaluate the influences of temperature, relative velocity, interface pressure, and frictional stroke independently. Based on the results of the experimental friction tests, a friction model is created. The resulting friction model is integrated into the numerical joining process simulation via a subroutine. To validate the quality of the new friction modeling, the results of simulations are compared with the experiments in terms of load-stroke diagrams, joint geometry, and hardness mappings on the microsection.

In order to predict relevant properties of clinched joints and to ensure the reliability of the process, it is numerically simulated during the product development process. The prediction accuracy of the simulated process depends on the implemented friction model. Therefore, a new method for determining friction coefficients in sheet metal materials was developed and tested. The aim of this study is the numerical investigation of this experimental method by means of FE simulation. The experimental setup is modelled in a 3D numerical simulation taking into account the process parameters varying in the experiment, such as geometric properties, contact pressure and contact velocity. Furthermore, the contact description of the model is calibrated via the experimentally determined friction coefficients according to clinch-relevant parameter space. It is shown that the assumptions made in the determination of the experimental data in preliminary work are valid. In addition, it is investigated to what extent the standard Coulomb friction model in the FEM can reproduce the results of the experimental method.

In general, the conditions in a deep-drawing process change due to changing tribology conditions, varying degrees of spring back, or scattering material properties in the sheet blanks, which affects the resulting pre-strain. Mechanical joining processes, especially clinching, are influenced by these process-related pre-strains. The final geometric shape of a clinched joint is affected to a significant level by the prior material deformation when joining with constant process parameters. That leads to a change in the stiffness and force transmission in the clinched joint due to the different geometric dimensions, such as interlock, neck thickness and bottom thickness, which directly affect the load bearing capacity. Here, the influence of the pre-straining in the deep drawing process on the force distribution in clinch points in an automotive assembly is investigated by finite-element models numerically. In further studies, the results are implemented in an optimization tool for designing clinched components. The methodology starts with a pre-straining of metal sheets. This step is followed by 2D rotationally symmetric forming simulations of the joining process. The resulting mesh of each forming simulation is rotated and 3D models are obtained. The clinched joint solid model with pre-strains is used further to determine the joint stiffnesses. With the simulation of the same test set-up with an equivalent point-connector model, the equivalent stiffness for each pre-strain combination is determined. Simulations are performed on a clinched component to assess the influence of pre-strain and sheet thinning on the clinched joint loadings by using the equivalent stiffnesses. The investigations clearly show that for the selected component, the loadings at the clinch points are dependent on the sheet thinning and the stiffnesses due to pre-strain. The magnitude of the influence varies depending on the quantity considered. For example, the shear force is more sensitive to the joint stiffness than to the sheet thinning."}],"publication":"Production Engineering","doi":"10.1007/s11740-021-01103-w","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s11740-021-01103-w"}],"publication_status":"published","date_updated":"2023-04-28T11:57:22Z","publication_identifier":{"issn":["0944-6524","1863-7353"]},"author":[{"full_name":"Martin, Sven","first_name":"Sven","last_name":"Martin","id":"38177"},{"id":"34782","last_name":"Bielak","first_name":"Christian Roman","full_name":"Bielak, Christian Roman"},{"id":"7850","first_name":"Mathias","last_name":"Bobbert","full_name":"Bobbert, Mathias"},{"full_name":"Tröster, Thomas","last_name":"Tröster","first_name":"Thomas","id":"553"},{"id":"32056","first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","full_name":"Meschut, Gerson"}],"year":"2022","title":"Numerical investigation of the clinched joint loadings considering the initial pre-strain in the joining area"},{"conference":{"name":"20th European Conference on Composite Materials (ECCM20)","start_date":"26.06.2022","location":"Lausanne","end_date":"28.06.2022"},"status":"public","_id":"44269","page":"730-739","volume":2,"user_id":"7850","citation":{"mla":"Tittmann, Karsten, et al. “Service Strength Analysis Method for Adhesively Bonded Hybrid Structures under Multiaxial Loading.” Proceedings of the 20th European Conference on Composite Materials, edited by Ecole Polytechnique Fédérale de Lausanne (EPFL), vol. 2, 2022, pp. 730–39.","ama":"Tittmann K, Koch I, Çavdar S, Gude M, Meschut G.

However, during the joint preparation for the MA, geometric features of the joint can change due to elastic effects and closing cracks. X-ray computed tomography (CT) is a promising alternative to investigate the joint non-estructively. However, if the material properties of similar joining partners are the same, the CT is not able to correctly resolve surfaces in the joint that are close to or pressing onto each other. These surfaces are relevant for the determination of characteristic dimensions such as neck thickness and undercut. By placing a thin, highly radiopaque tin layer between the joining partners, the interfacial area in the reconstructed volume can be highlighted. In this work, a method for the localisation of the tin layer inside the joint as well as threshold value procedures for the outer joint contour in cross section images are investigated. The measured characteristic dimensions are compared with measured values from MA of the same samples and of samples without tin layer. In addition, possible effects of the tin layer on the joining point characteristics as well as problems of the MA are discussed.\r\n"}],"issue":"12","publication":"e-Journal of Nondestructive Testing","doi":"10.58286/27519","language":[{"iso":"eng"}],"intvolume":" 27","date_updated":"2025-06-02T20:19:07Z","publication_status":"published","publication_identifier":{"issn":["1435-4934"]},"author":[{"full_name":"Busch, Matthias","first_name":"Matthias","last_name":"Busch"},{"first_name":"Daniel","last_name":"Köhler","full_name":"Köhler, Daniel"},{"first_name":"Tino","last_name":"Hausotte","full_name":"Hausotte, Tino"},{"first_name":"Robert","last_name":"Kupfer","full_name":"Kupfer, Robert"},{"full_name":"Troschitz, Juliane","last_name":"Troschitz","first_name":"Juliane"},{"full_name":"Gude, Maik","last_name":"Gude","first_name":"Maik"}],"title":"Approach to Determine the Characteristic Dimensions of Clinched Joints by Industrial X-ray Computed Tomography","year":"2022","project":[{"name":"TRR 285: TRR 285","grant_number":"418701707","_id":"130"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C04: TRR 285 - Subproject C04","_id":"148"},{"_id":"149","name":"TRR 285 – C05: TRR 285 - Subproject C05"}],"citation":{"ieee":"M.

Dagegen kann mit der in-situ Computertomographie (CT) der innere Deformationszustand des Clinchpunkts, z.B. während eines Scherzugversuchs, untersucht werden. Hierbei ist es für artgleiche Werkstoffe aufgrund der hohen Pressungen im Clinchpunkt schwierig, die Trennfläche zwischen den Fügepartnern im CT-Scan zu erkennen. Daher wird eine radioopake Zwischenschicht aus Zinn in die Trennfläche eingebracht. In dieser Arbeit wird der Einfluss der Zwischenschicht auf die in-situ CT-Scherzugprüfung untersucht.

To assure the clinch point’s quality, the force displacement curve during clinching or the bottom thickness are monitored. The most significant geometrical characteristics of the clinch point, neck thickness and undercut, are usually tested destructively by microsectioning. However, micrograph preparation goes ahead with a resetting of elastic deformations and crack-closing after unloading. To generate a comprehensive knowledge of the clinch point’s inner geometry under load, in-situ computed tomography (CT) and acoustic testing (TDA) can be combined. While the TDA is highly sensitive to the inner state of the clinch point, it could detect critical events like crack development during loading. If such events are indicated, the loading process is stopped and a stepped in-situ CT of the following crack and deformation development is performed. In this paper, the concept is applied to the process of clinching itself, providing a detailed three-dimensional insight in the development of the joining zone. A test set-up is used which allows a stepwise clinching of two aluminium sheets EN AW 6014. Furthermore, this set-up is positioned within a CT system. In order to minimize X-ray absorption, a beryllium cylinder is used within the set-up frame and clinching tools are made from Si3N4. The actuator and sensor necessary for the TDA are integrated in the set-up. In regular process steps, the clinching process is interrupted in order to perform a TDA and a CT scan. In order to enhance the visibility of the interface, a thin tin layer is positioned between the sheets prior clinching. It is shown, that the test-set up allows a monitoring of the dynamic behaviour of the specimen during clinching while the CT scans visualize the inner geometry and material flow non-destructively.","lang":"eng"}],"publication":"Key Engineering Materials","department":[{"_id":"157"},{"_id":"43"}],"type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"date_created":"2024-02-06T15:04:45Z","intvolume":" 926","publication_status":"published","date_updated":"2025-06-02T20:21:13Z","author":[{"full_name":"Köhler, Daniel","last_name":"Köhler","first_name":"Daniel"},{"full_name":"Stephan, Richard","last_name":"Stephan","first_name":"Richard"},{"last_name":"Kupfer","first_name":"Robert","full_name":"Kupfer, Robert"},{"full_name":"Troschitz, Juliane","last_name":"Troschitz","first_name":"Juliane"},{"full_name":"Brosius, Alexander","first_name":"Alexander","last_name":"Brosius"},{"full_name":"Gude, Maik","last_name":"Gude","first_name":"Maik"}],"publication_identifier":{"issn":["1662-9795"]},"title":"Investigations on Combined <i>In Situ</i> CT and Acoustic Analysis during Clinching","year":"2022","doi":"10.4028/p-32330d","language":[{"iso":"eng"}],"project":[{"name":"TRR 285: TRR 285","grant_number":"418701707","_id":"130"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"148","name":"TRR 285 – C04: TRR 285 - Subproject C04"}],"citation":{"mla":"Köhler, Daniel, et al. “Investigations on Combined <I>In Situ</I> CT and Acoustic Analysis during Clinching.” Key Engineering Materials, vol. 926, Trans Tech Publications, Ltd., 2022, pp. 1489–97, doi:10.4028/p-32330d.","ama":"Köhler D, Stephan R, Kupfer R, Troschitz J, Brosius A, Gude M.

A new approach is the use of high nitrogen steel as rivet material, which allows to omit the usually necessary heat treatment and coating and thus leads to a shortening of the process chain. Due to the high strain hardening, however, high tool loads must be expected. Thus, appropriate forming strategies are needed. Within this contribution, the influence of applying different temperatures for each forming stage in a two-stage rivet forming process using the high nitrogen steel 1.3815 is investigated. The findings provide a basic understanding of the influence of the temperature management when forming high nitrogen steel. For this purpose, the rivets are not formed at the same temperature in each stage, but an elevated temperature is applied selectively. Different process routes are investigated. First, cups are manufactured in stage 1 at room temperature, followed by stage 2 at 200°C. Second, cups are formed in stage 1 at 200°C and used for stage 2 at room temperature. By comparing the findings with results when applying the same temperature in both stages, it is shown that the temperature during the first forming operation has an effect on the forming behaviour during the second forming stage. The required forming forces and the resulting rivet hardness can be influenced by process-adapted temperature application. Furthermore, the causes for the temperature impact on the residual cup thickness in stage 1 are evaluated by a cause and effect analysis, which provides a deeper process understanding. The thermal expansion of the tool and the billet as well as the improved forming behaviour at 200°C are identified as the main influencing causes on the achieved residual cup thickness.","lang":"eng"}],"date_created":"2022-04-07T06:52:04Z","department":[{"_id":"157"}],"type":"journal_article","publication_identifier":{"issn":["1464-4207"]},"author":[{"first_name":"Clara-Maria","last_name":"Kuball","full_name":"Kuball, Clara-Maria"},{"id":"38131","last_name":"Uhe","first_name":"Benedikt","full_name":"Uhe, Benedikt"},{"id":"32056","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson","full_name":"Meschut, Gerson"},{"first_name":"Marion","last_name":"Merklein","full_name":"Merklein, Marion"}],"year":"2022","title":"Process-adapted temperature application within a two-stage rivet forming process for high nitrogen steel","status":"public","date_updated":"2026-02-27T10:21:22Z","publication_status":"published","language":[{"iso":"eng"}],"_id":"30847","page":"1-17","doi":"10.1177/14644207211068693","user_id":"53912"},{"type":"journal_article","keyword":["Metals and Alloys","Mechanical Engineering","Mechanics of Materials"],"department":[{"_id":"157"}],"date_created":"2024-03-18T11:51:57Z","abstract":[{"lang":"eng","text":"During resistance spot welding of zinc-coated advanced high-strength steels (AHSSs) for automotive production, liquid metal embrittlement (LME) cracking may occur in the event of a combination of various unfavorable influences. In this study, the interactions of different welding current levels and weld times on the tendency for LME cracking in third-generation AHSSs were investigated. LME manifested itself as high-penetration cracks around the circumference of the spot welds for welding currents closely below the expulsion limit. At the same time, the observed tendency for LME cracking showed no direct correlation with the overall heat input of the investigated welding processes. To identify a reliable indicator of the tendency for LME cracking, the local strain rate at the origin of the observed cracks was analyzed over the course of the welding process via finite element simulation. While the local strain rate showed a good correlation with the process-specific LME cracking tendency, it was difficult to interpret due to its discontinuous course. Therefore, based on the experimental measurement of electrode displacement during welding, electrode indentation velocity was proposed as a descriptive indicator for quantifying cracking tendency."}],"publication":"Welding Journal","issue":"7","doi":"10.29391/2022.101.015","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2025-08-07T09:29:30Z","intvolume":" 101","year":"2022","title":"The Influence of Electrode Indentation Rate on LME Formation during RSW","publication_identifier":{"issn":["0043-2296","2689-0445"]},"author":[{"id":"22483","last_name":"Böhne","first_name":"Christoph","full_name":"Böhne, Christoph"},{"id":"32056","first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson"},{"last_name":"BIEGLER","first_name":"MAX","full_name":"BIEGLER, MAX"},{"first_name":"MICHAEL","last_name":"RETHMEIER","full_name":"RETHMEIER, MICHAEL"}],"quality_controlled":"1","popular_science":"1","citation":{"ama":"Böhne C, Meschut G, BIEGLER M, RETHMEIER M.

Hence, this group of alloys is often used in the automotive sector. The challenge for this application is the brittle character of these alloys which leads to cracks during joint formation when mechanical joining technologies are used. A rise in ductility can be achieved by a considerable increase in the solidification rate which results in grain refinement. High solidification rates can be realized in twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9 (for European Norm - aluminum cast product) is manufactured by the TRC process and analyzed. Subsequently, joining investigations are performed on castings in as-cast and heat-treated condition using the self-piercing riveting process considering the joint formation and the load-bearing capacity. Due to the fine microstructure, the crack initiation can be avoided during joining, while maintaining the joining parameters, especially by specimens in heat treatment conditions. Furthermore, due to the extremely fine microstructure, the load-bearing capacity of the joint can be significantly increased in terms of the maximum load-bearing force and the energy absorbed.","lang":"eng"}],"_id":"36332","publisher":"Wiley","volume":24,"user_id":"7850","status":"public","oa":"1","citation":{"mla":"Neuser, Moritz, et al. “Mechanical Properties and Joinability of AlSi9 Alloy Manufactured by Twin‐Roll Casting.” Advanced Engineering Materials, vol. 24, no. 10, 2200874, Wiley, 2022, doi:10.1002/adem.202200874.","bibtex":"@article{Neuser_Kappe_Ostermeier_Krüger_Bobbert_Meschut_Schaper_Grydin_2022, title={Mechanical Properties and Joinability of AlSi9 Alloy Manufactured by Twin‐Roll Casting}, volume={24}, DOI={10.1002/adem.202200874}, number={102200874}, journal={Advanced Engineering Materials}, publisher={Wiley}, author={Neuser, Moritz and Kappe, Fabian and Ostermeier, Jakob and Krüger, Jan Tobias and Bobbert, Mathias and Meschut, Gerson and Schaper, Mirko and Grydin, Olexandr}, year={2022} }","ama":"Neuser M, Kappe F, Ostermeier J, et al.

An experimental investigation is conducted to determine the failure modes of clinched joints under cyclic loading at different load amplitudes with single-lap shear tests. In addition, numerical FEM simulations of clinching process and subsequent shear loading are performed to support the experimental investigations by analyzing the state of stresses at the location of failure. An attempt is made to explain the location of crack initiation in the experiments using evaluation variables such as contact shear stress and maximum principal stress."}],"date_created":"2022-04-27T09:02:05Z","keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering"],"type":"journal_article","department":[{"_id":"157"}]}]
