These are frequently applied in the form of multi-material systems, which are characterized by the selective use of materials and geometries. One major challenge in the manufacturing of multi-material systems is the joining of the individual components to form a complete system. Mechanical joining processes such as semi-tubular self-piercing riveting are frequently used for this application but reach their limits concerning the number of combinations of geometry and material. In order to react to the requirements and to increase the versatility of semi-tubular self-pierce riveting, a process combination consisting of a tumbling process and a self-pierce riveting process has been presented previously. This process combination is used in this work to investigate the versatility and to identify the influencing parameters on it. For this purpose, experiments are conducted to identify process-side influence possibilities. The tests are performed with a dual-phase steel aluminum alloy to represent the varying mechanical characteristics of multi-material systems. Furthermore, the initial sheet thicknesses of the joining partners are varied in several steps. In addition to the geometric joint formation used to describe the undercut, the rivet head end position and the residual sheet thickness, the joining process, is also analyzed during the investigations. Further, the innovative joining process is evaluated by comparing it with a conventional self-piercing riveting process. The knowledge obtained represents a basis for the identification and evaluation of the versatility of the process combination.

In addition to experimental investigations, numerical studies are indispensable tools for its development. Therefore, this paper includes an analysis of boundary conditions for the spatial discretization and mesh modeling techniques, the material modeling, the contact and friction modeling, and the thermal boundary conditions for the finite element (FE) modeling of this joining process. For these investigations, two FE models corresponding to the two process steps were set up and compared with the two related processes of friction stir welding and friction drilling. Regarding the spatial discretization, the Lagrangian approach is not sufficient to represent the deformation that occurs. The Johnson-Cook model is well suited as a material model. The modeling of the contact detection and friction are important research subjects. Coulomb’s law of friction is not adequate to account for the complex friction phenomena of the adaptive joining process. The thermal boundary conditions play a decisive role in heat generation and thus in the material flow of the process. It is advisable to use temperature-dependent parameters and to investigate in detail the influence of radiation in the entire process.","lang":"eng"}],"issue":"5","publication":"Metals","doi":"10.3390/met12050869","language":[{"iso":"eng"}],"article_number":"869","intvolume":" 12","publication_status":"published","date_updated":"2023-04-27T09:39:39Z","author":[{"id":"44917","first_name":"Annika","last_name":"Oesterwinter","full_name":"Oesterwinter, Annika"},{"id":"72219","last_name":"Wischer","first_name":"Christian","full_name":"Wischer, Christian"},{"full_name":"Homberg, Werner","last_name":"Homberg","first_name":"Werner"}],"publication_identifier":{"issn":["2075-4701"]},"year":"2022","title":"Identification of Requirements for FE Modeling of an Adaptive Joining Technology Employing Friction-Spun Joint Connectors (FSJC)"},{"_id":"34224","publisher":"MDPI AG","user_id":"45673","volume":12,"status":"public","citation":{"bibtex":"@article{Joy_Weiß_Schramm_Kullmer_2022, title={Further Development of 3D Crack Growth Simulation Program to Include Contact Loading Situations}, volume={12}, DOI={10.3390/app12157557}, number={157557}, journal={Applied Sciences}, publisher={MDPI AG}, author={Joy, Tintu David and Weiß, Deborah and Schramm, Britta and Kullmer, Gunter}, year={2022} }","ama":"Joy TD, Weiß D, Schramm B, Kullmer G.

Adapcrack3D is a simulation program that can accurately predict the propagation of cracks in real structures. However, until now, this three-dimensional program has only considered mechanical loads and static thermal loads. Therefore, the features of Adapcrack3D have been extended by including contact loading in crack growth simulations. The numerical simulation of crack propagation with Adapcrack3D is generally carried out using FE models of structures provided by the user. For simulating models with contact loading situations, Adapcrack3D has been updated to work with FE models containing multiple parts and necessary features such as coupling and surface interactions. Because Adapcrack3D uses the submodel technique for fracture mechanical evaluations, the architecture of the submodel is also modified to simulate models with contact definitions between the crack surfaces. This paper discusses the newly implemented attribute of the program with the help of illustrative examples. The results confirm that the contact simulation in Adapcrack3D is a major step in improving the functionality of the program.","lang":"eng"}]},{"project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"name":"TRR 285 – B04: TRR 285 - Subproject B04","_id":"143"}],"citation":{"chicago":"Weiß, Deborah, Britta Schramm, and Gunter Kullmer. “Influence of Plane Mixed-Mode Loading on the Kinking Angle of Clinchable Metal Sheets.” In Procedia Structural Integrity, 39:139–47.

The reasons for this are the variety of joining possibilities as well as high load-bearing capacities. However, the currently rigid tooling systems cannot react to changing boundary conditions, such as changed sheet thicknesses or strength. For this reason, a large number of specialised joining processes have been developed to expand the range of applications. Using a versatile self-piercing riveting process, multi-material structures are joined in this paper. In this process, a modified tool actuator technology is combined with multi-range capable auxiliary joining parts. The multi-range capability of the rivets is achieved by forming the rivet head onto the respective thickness of the joining part combination without creating a tooling set-up effort. The joints are investigated both experimentally on the basis of joint formation and load-bearing capacity tests as well as by means of numerical simulation. It turned out that all the joints examined could be manufactured according to the defined standards. The load-bearing capacities of the joints are comparable to those of conventionally joined joints. In some cases the joint fails prematurely, which is why lower energy absorptions are obtained. However, the maximum forces achieved are higher than those of conventional joints. Especially in the case of high-strength materials arranged on the die side, the interlock formation is low. In addition, the use of die-sided sheets requires a large deformation of the rivet head protrusion, which leads to an increase in stress and, as a result, to damage if the rivet head. However, a negative influence on the joint load-bearing capacity could be excluded."}],"publication":"Production Engineering","type":"journal_article","keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering"],"department":[{"_id":"157"},{"_id":"630"}],"date_created":"2022-12-06T13:50:06Z"},{"citation":{"apa":"Zirngibl, C., Kügler, P., Popp, J., Bielak, C.

Therefore, not only the design of an individual joint is required but also the dimensioning of the entire joining connection is crucial. However, in comparison to thermal joining techniques, such as spot welding, the evaluation of the joints’ resistance against defined requirements (e.g. types of load, minimal amount of load cycles) mainly relies on the consideration of expert knowledge, a few design principles and a small amount of experimental data. Since this generally implies the involvement of several domains, such as the material characterization or the part design, a tremendous amount of data and knowledge is separately generated for a certain dimensioning process. Nevertheless, the lack of formalization and standardization in representing the gained knowledge leads to a difficult and inconsistent reuse, sharing or searching of already existing information. Thus, this contribution presents a specific ontology for the provision of cross-domain knowledge about mechanical joining processes and highlights two potential use cases of this ontology in the design of clinched and pin joints.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1007/s11740-022-01117-y","title":"Provision of cross-domain knowledge in mechanical joining using ontologies","year":"2022","publication_identifier":{"issn":["0944-6524","1863-7353"]},"author":[{"first_name":"Christoph","last_name":"Zirngibl","full_name":"Zirngibl, Christoph"},{"full_name":"Kügler, Patricia","first_name":"Patricia","last_name":"Kügler"},{"last_name":"Popp","first_name":"Julian","full_name":"Popp, Julian"},{"last_name":"Bielak","first_name":"Christian Roman","full_name":"Bielak, Christian Roman","id":"34782"},{"id":"7850","last_name":"Bobbert","first_name":"Mathias","full_name":"Bobbert, Mathias"},{"full_name":"Drummer, Dietmar","first_name":"Dietmar","last_name":"Drummer"},{"id":"32056","full_name":"Meschut, Gerson","first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246"},{"first_name":"Sandro","last_name":"Wartzack","full_name":"Wartzack, Sandro"},{"first_name":"Benjamin","last_name":"Schleich","full_name":"Schleich, Benjamin"}],"date_updated":"2023-04-27T07:42:19Z","publication_status":"published"},{"publication":"Materials Design and Applications IV","abstract":[{"lang":"eng","text":"Due to economic and ecological requirements and the associated trend towards lightweight construction, mechanical joining technologies like self-piercing riveting are gaining in importance. In addition, the increase in lightweight multi-material joints has led to the development of many different mechanical joining technologies which can only be applied to join a small number of material combinations. This leads to low process efficiency, and in the case of self-piercing riveting, to a large number of required tool changes. Another approach focuses on reacting to changing boundary conditions as well as the creation of customised joints by using adaptive tools, versatile auxiliary joining parts or modified process kinematics. Therefore, this study investigates the influence of increased die-sided kinematics on joint formation in self-piercing riveting process. The aim is to achieve an improvement of the joint properties by superimposing the punch feed. Furthermore, it is intended to reduce required tool changes due to the improved joint design. The investigations were carried out by means of a 2D-axisymmetric numerical simulation model using the LS-Dyna simulation software. After the validation of the process model, the die was extended to include driven die elements. Using the model, different kinematics as well as their effects on the joint formation and the internal stress concentration could be analysed. In principle, the increased actuator technology enabled an increase of the interlock formation for both pure aluminium and multi-material joints consisting of steel and aluminium.

In contrast to strength calculation the fracture mechanics assumes the existence of cracks which might further propagate due to the operational load. First, the present paper illustrates the general procedure of a fracture mechanical evaluation of fatigue cracks in order to assess practical damage cases.

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.","lang":"eng"}],"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","author":[{"id":"38177","full_name":"Martin, Sven","first_name":"Sven","last_name":"Martin"},{"id":"34782","last_name":"Bielak","first_name":"Christian Roman","full_name":"Bielak, Christian Roman"},{"first_name":"Mathias","last_name":"Bobbert","full_name":"Bobbert, Mathias","id":"7850"},{"id":"553","last_name":"Tröster","first_name":"Thomas","full_name":"Tröster, Thomas"},{"orcid":"0000-0002-2763-1246","first_name":"Gerson","last_name":"Meschut","full_name":"Meschut, Gerson","id":"32056"}],"publication_identifier":{"issn":["0944-6524","1863-7353"]},"title":"Numerical investigation of the clinched joint loadings considering the initial pre-strain in the joining area","year":"2022","oa":"1","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"name":"TRR 285 – A01: TRR 285 - Subproject A01","_id":"135"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"_id":"140","name":"TRR 285 – B01: TRR 285 - Subproject B01"}],"quality_controlled":"1","citation":{"ieee":"S.

Hierzu werden sowohl Kraft-Verlängerungs-Kurven als auch die Geometrie der Clinchpunkte während der Belastung verglichen.","lang":"ger"}],"project":[{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285: TRR 285","grant_number":"418701707","_id":"130"},{"name":"TRR 285 – C04: TRR 285 - Subproject C04","_id":"148"}],"publication":"Tagungsband zur Werkstoffprüfung 2022","citation":{"short":"D.
