One way to meet these challenges is to carry out the forming processes in closed-loop control systems using softsensors. Despite the many potential applications of softsensors in the field of forming technology, there is still no definition of the term softsensor. This publication therefore proposes a definition of the softsensor based on the definition of a sensor and the distinction from the observer, which on the one hand is intended to stimulate scientific discourse and on the other hand is also intended to form the basis for further scientific work. Based on this definition, a wide variety of highly topical application examples of various softsensors in the field of forming technology are given.</jats:p>","lang":"eng"}],"publication":"Production Engineering"},{"_id":"34213","publisher":"Springer Science and Business Media LLC","page":"305-313","volume":16,"user_id":"7850","status":"public","citation":{"bibtex":"@article{Ewenz_Bielak_Otroshi_Bobbert_Meschut_Zimmermann_2022, title={Numerical and experimental identification of fatigue crack initiation sites in clinched joints}, volume={16}, DOI={<a href=\"https://doi.org/10.1007/s11740-022-01124-z\">10.1007/s11740-022-01124-z</a>}, number={2–3}, journal={Production Engineering}, publisher={Springer Science and Business Media LLC}, author={Ewenz, L. and Bielak, Christian Roman and Otroshi, Mortaza and Bobbert, Mathias and Meschut, Gerson and Zimmermann, M.}, year={2022}, pages={305–313} }","ama":"Ewenz L, Bielak CR, Otroshi M, Bobbert M, Meschut G, Zimmermann M.

In spaceframe technology, both sheet metal and continuous cast are joined to castings at the nodal points of the chassis. Since resistance spot welding is not an option when different materials are joined, research is focusing on mechanical joining methods for multi-material designs. To reduce weight and achieve the required strength, hardenable cast aluminium alloys of the AlSi-system are widely used. Thus, 85–90% of aluminium castings in the automotive industry are comprised of the AlSi-system. Due to the limited weldability, mechanical joining is a suitable process. For this application, various optimisation strategies are required to produce a crack-free joint, as the brittle character of the AlSi alloy poses a challenge. Thus, adapted castings with appropriate ductility are needed. Hence, in this study, the age-hardenable cast aluminium alloy AlSi10Mg is investigated regarding the correlation of the different thicknesses, the microstructural characteristics as well as the resulting mechanical properties. A variation of the thicknesses leads to different solidification rates, which in turn affect the microstructure formation and are decisive for the mechanical properties of the casting as well as the joinability. For the investigation, plates with thicknesses from 2.0 to 4.0 mm, each differing by 0.5 mm, are produced via sand casting. Hence, the overall aim is to evaluate the joinability of AlSi10Mg and derive conclusions concerning the microstructure and mechanical properties.</jats:p>"}],"publication":"Production Engineering","doi":"10.1007/s11740-022-01106-1","language":[{"iso":"eng"}],"article_type":"original","publication_status":"published","date_updated":"2024-03-14T15:21:51Z","publication_identifier":{"issn":["0944-6524","1863-7353"]},"author":[{"first_name":"Moritz","last_name":"Neuser","full_name":"Neuser, Moritz","id":"32340"},{"full_name":"Grydin, Olexandr","first_name":"Olexandr","last_name":"Grydin","id":"43822"},{"full_name":"Frolov, Y.","first_name":"Y.","last_name":"Frolov"},{"last_name":"Schaper","first_name":"Mirko","full_name":"Schaper, Mirko","id":"43720"}],"year":"2022","title":"Influence of solidification rates and heat treatment on the mechanical performance and joinability of the cast aluminium alloy AlSi10Mg","project":[{"_id":"130","grant_number":"418701707","name":"TRR 285: TRR 285"},{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"_id":"136","name":"TRR 285 – A02: TRR 285 - Subproject A02"}],"quality_controlled":"1","citation":{"ama":"Neuser M, Grydin O, Frolov Y, Schaper M.

An integrated securing of the joinability in versatile process chains is currently hardly possible as the number of combinable tool variants as well as variable force- and path-based process parameters is infinite. A versatile process chain, i.e. a sequence of all the processes and process steps required for product manufacturing, enables targeted changes to the semi-finished product, the joint, the component or the joining process that exceed the originally planned extend while still ensuring joinability. In detail, it leads to a unique joint with its own mechanical property profile, which, against the background of the resulting infinite number of combinations, makes it impossible to secure the joinability on the conventional experimentally based approach without extensive safety factors. The Transregional Colaborative Research Center 285 (TCRC285), which also initiated this special issue, is intended to enable mechanical joining technology to be versatile in the sense of high application flexibility. This is to be achieved with a numerical representation of the complete process chain from the incoming semi finished product via the joining part production and the joining process to the property profile of the joint in the operating phase. Thus a predictability of the joinability can be achieved and improvements in the individual life cycles of a joint can be realized by grasping the cause-and-effect relationships. On the basis of this knowledge, new possibilities for intervention in the joining process are to be created for the adaptation of the joining processes. With the aid of the methods developed for this purpose, tools will later be available to the end user to substitute the large number of mechanical joining processes or joining task-specific configurations with a smaller number of adaptable processes. This expands the flexibility in material choices, enabling challenges in environmental issues and sustainability to be overcome."}],"language":[{"iso":"eng"}],"doi":"10.1007/s11740-022-01125-y","author":[{"last_name":"Meschut","first_name":"Gerson","full_name":"Meschut, Gerson"},{"full_name":"Merklein, Marion","first_name":"Marion","last_name":"Merklein"},{"last_name":"Brosius","first_name":"Alexander","full_name":"Brosius, Alexander"},{"full_name":"Bobbert, Mathias","last_name":"Bobbert","first_name":"Mathias"}],"publication_identifier":{"issn":["0944-6524","1863-7353"]},"title":"Mechanical joining in versatile process chains","year":"2022","intvolume":"        16","publication_status":"published","date_updated":"2023-03-29T08:32:24Z","citation":{"apa":"Meschut, G., Merklein, M., Brosius, A., &#38; Bobbert, M.

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.</jats:p>","lang":"eng"}],"publication":"Production Engineering","user_id":"7850","_id":"34241","publisher":"Springer Science and Business Media LLC","status":"public","project":[{"_id":"130","grant_number":"418701707","name":"TRR 285: TRR 285"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"146","name":"TRR 285 – C02: TRR 285 - Subproject C02"}],"quality_controlled":"1","citation":{"mla":"Kappe, Fabian, et al. “Joining of Multi-Material Structures Using a Versatile Self-Piercing Riveting Process.” <i>Production Engineering</i>, Springer Science and Business Media LLC, 2022, doi:<a href=\"https://doi.org/10.1007/s11740-022-01151-w\">10.1007/s11740-022-01151-w</a>.","bibtex":"@article{Kappe_Wituschek_Bobbert_Lechner_Meschut_2022, title={Joining of multi-material structures using a versatile self-piercing riveting process}, DOI={<a href=\"https://doi.org/10.1007/s11740-022-01151-w\">10.1007/s11740-022-01151-w</a>}, journal={Production Engineering}, publisher={Springer Science and Business Media LLC}, author={Kappe, Fabian and Wituschek, Simon and Bobbert, Mathias and Lechner, Michael and Meschut, Gerson}, year={2022} }","ama":"Kappe F, Wituschek S, Bobbert M, Lechner M, Meschut G.

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.

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.</jats:p>"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s11740-021-01103-w"}],"doi":"10.1007/s11740-021-01103-w","publication_identifier":{"issn":["0944-6524","1863-7353"]},"author":[{"first_name":"Sven","last_name":"Martin","full_name":"Martin, Sven","id":"38177"},{"full_name":"Bielak, Christian Roman","last_name":"Bielak","first_name":"Christian Roman","id":"34782"},{"first_name":"Mathias","last_name":"Bobbert","full_name":"Bobbert, Mathias","id":"7850"},{"id":"553","last_name":"Tröster","first_name":"Thomas","full_name":"Tröster, Thomas"},{"first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","full_name":"Meschut, Gerson","id":"32056"}],"title":"Numerical investigation of the clinched joint loadings considering the initial pre-strain in the joining area","year":"2022","publication_status":"published","date_updated":"2023-04-28T11:57:22Z","oa":"1","citation":{"ieee":"S.

Cracks can propagate due to operational loads and consequently lead to component failure. The fracture mechanical analysis provides information on stable or unstable crack growth as well as about the direction and the growth rate of a crack. For this purpose, sufficient information has to be available about the crack location, the crack length, the component geometry, the component loading and the fracture mechanical material parameters. The fracture mechanical properties are determined experimentally with standardized specimens as defined by the guidelines of the American Society for Testing and Materials. In practice, however, especially in the context with damage cases or formed material fracture mechanical parameters directly for a component are of interest. However, standard specimens often cannot be extracted at all due to the complexity of the component geometry. Therefore, the development of special specimens is required whereby certain arrangements have to be made in advance. These arrangements are presented in the present paper in order to contribute to a holistic investigation chain for the experimental determination of fracture mechanical material parameters with special specimens.</jats:p>"}],"quality_controlled":"1","publication":"Production Engineering","citation":{"chicago":"Weiß, Deborah, Britta Schramm, and Gunter Kullmer. “Holistic Investigation Chain for the Experimental Determination of Fracture Mechanical Material Parameters with Special Specimens.” <i>Production Engineering</i>, 2021. <a href=\"https://doi.org/10.1007/s11740-021-01096-6\">https://doi.org/10.1007/s11740-021-01096-6</a>.","short":"D.

To influence the process temperature, two main process parameters, i.e. the rotation speed and the feed rate, can be adapted. With the objective to improve the tool performance and the quality of the workpiece, this study focuses on a coating concept for friction-spinning tools made of high speed steel (HS6 5 2C, 1.3343). On the one hand, atmospheric plasma sprayed (APS) Al2O3 and ZrO2-8Y2O3 coatings serve as a thermal insulator, and, on the other hand, physically vapor deposited (PVD) TiAlSi7.9N and CrAlSi7.5N films are applied to increase the hardness and wear resistance of the tools. In addition, duplex coatings, combining the APS and PVD technique, are synthesized to influence both the heat transfer and the tribological properties of friction-spinning tools.\r\nSubsequently, all coated tools are tested in a friction-spinning process to form flanges made of AW-6060 (AlMgSi   3.3206) tube materials. The tool temperatures are determined in-situ to investigate the impact of the tool coating on the process temperature. Compared to an uncoated tool, the alumina and zirconia coatings contribute to a reduction of the tool temperature by up to half, while the PVD films increase the hardness of the tool by 20 GPa. Furthermore, it is shown that the surface quality of thermally sprayed (TS) or PVD coated tools is directly related to the surface roughness of the resulting workpiece.\r\n"}],"publication":"Production Engineering","citation":{"short":"W.
