Multi-material design and the increasing trend towards producing large structural components using the megacasting process pose considerable challenges, particularly in the mechanical joining of aluminium-silicon (AlSi) castings. These castings typically exhibit low ductility and are prone to cracking when mechanically joined. Based on the excellent castability of hypoeutectic AlSi alloys, these are applied in sand casting and die casting as well as in megacasting. With a silicon content between 7 wt% and 12 wt%, these AlSi-alloys have a plate-like silicon phase that initiates cracks during mechanical joining. To enhance the joinability of castings, the research hypothesis is that improved solidification conditions enable a significant modification in the microstructure and therefore, increase the mechanical properties. During the manufacture of the castings using the sand casting process, the solidification conditions within the structural elements are varied to modify the microstructure to obtain castings with graded microstructure. The castings are evaluated using mechanical, microstructural and joining testing methods and finally, a microstructure-joinability correlation is established."}],"date_created":"2025-05-12T15:21:06Z","keyword":["Joining","Casting","Self-pierce riveting","Aluminium casting alloy"],"type":"journal_article","department":[{"_id":"43"},{"_id":"158"},{"_id":"157"},{"_id":"9"},{"_id":"321"}],"status":"public","conference":{"end_date":"2025-06-05","start_date":"2025-06-02","name":"44th Conference of the International Deep Drawing Research Group (IDDRG 2025)","location":"Lissabon (Portugal)"},"_id":"59872","user_id":"7850","volume":408,"citation":{"bibtex":"@article{Neuser_Schlichter_Hoyer_Bobbert_Meschut_Schaper_2025, title={Mechanical joinability of microstructurally graded structural components manufactured from hypoeutectic aluminium casting alloys}, volume={408}, DOI={<a href=\"https://doi.org/10.1051/matecconf/202540801081\">10.1051/matecconf/202540801081</a>}, number={01081}, journal={44th Conference of the International Deep Drawing Research Group (IDDRG 2025)}, author={Neuser, Moritz and Schlichter, Malte Christian and Hoyer, Kay-Peter and Bobbert, Mathias and Meschut, Gerson and Schaper, Mirko}, year={2025} }","chicago":"Neuser, Moritz, Malte Christian Schlichter, Kay-Peter Hoyer, Mathias Bobbert, Gerson Meschut, and Mirko Schaper. “Mechanical Joinability of Microstructurally Graded Structural Components Manufactured from Hypoeutectic Aluminium Casting Alloys.” <i>44th Conference of the International Deep Drawing Research Group (IDDRG 2025)</i> 408 (2025). <a href=\"https://doi.org/10.1051/matecconf/202540801081\">https://doi.org/10.1051/matecconf/202540801081</a>.","ama":"Neuser M, Schlichter MC, Hoyer K-P, Bobbert M, Meschut G, Schaper M.

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"}],"language":[{"iso":"eng"}],"doi":"10.21741/9781644903599-148","author":[{"id":"61977","full_name":"Schlichter, Malte Christian","last_name":"Schlichter","first_name":"Malte Christian"},{"id":"54972","full_name":"Harabati, Özcan","last_name":"Harabati","first_name":"Özcan"},{"id":"76631","first_name":"Jean-Patrick","last_name":"Ludwig","full_name":"Ludwig, Jean-Patrick"},{"full_name":"Böhnke, Max","last_name":"Böhnke","first_name":"Max","id":"45779"},{"id":"34782","first_name":"Christian Roman","last_name":"Bielak","full_name":"Bielak, Christian Roman"},{"id":"7850","full_name":"Bobbert, Mathias","last_name":"Bobbert","first_name":"Mathias"},{"full_name":"Meschut, Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","first_name":"Gerson","id":"32056"}],"publication_identifier":{"issn":["2474-395X"]},"title":"Experimental and numerical investigation of the influence of rolling-induced sheet metal deformation on SPR joints","year":"2025","intvolume":"        54","publication_status":"published","date_updated":"2026-02-24T14:02:01Z","citation":{"bibtex":"@inproceedings{Schlichter_Harabati_Ludwig_Böhnke_Bielak_Bobbert_Meschut_2025, title={Experimental and numerical investigation of the influence of rolling-induced sheet metal deformation on SPR joints}, volume={54}, DOI={<a href=\"https://doi.org/10.21741/9781644903599-148\">10.21741/9781644903599-148</a>}, booktitle={Materials Research Proceedings}, publisher={Materials Research Forum LLC}, author={Schlichter, Malte Christian and Harabati, Özcan and Ludwig, Jean-Patrick and Böhnke, Max and Bielak, Christian Roman and Bobbert, Mathias and Meschut, Gerson}, year={2025} }","ama":"Schlichter MC, Harabati Ö, Ludwig J-P, et al.

As a widely used sheet metal in clinched joints within the automotive industry, the aluminum alloy EN AW-6014 has been the focus of numerous studies. High-cycle fatigue (HCF) is a critical aspect when assessing the durability of clinched joints. In the present work, the HCF behavior of EN AW-6014 T4 was explored both experimentally and numerically. To model the fatigue behavior, Lemaitre’s two-scale damage model was used. Two key parameters, damage strength and damage exponent, are necessary for numerical investigations of HCF behavior. These parameters were determined through experiments with flat specimens and subsequently validated within a numerical model of clinched joints.

V-SPR enables adaptation to changing boundary conditions, such as a change in the material thickness combination, without varying the rivet die combination due to increased punch actuation and the use of multi-range capable rivets [1]. The inner punch first sets the rivet. The outer punch then forms the rivet head to the respective sheet thickness. For this, the rivet requires a hard shank and a ductile rivet head, which is achieved by an inductive local hardening process [2]. Until now, the joint formation of rivets with graded hardness profile has been challenging to estimate in the FEM simulation due to the inhomogeneous material conditions in the rivet. In this study, a method capable of reproducing the experimentally determined hardness levels of rivets in detail is shown. This FE model enables the realistic modelling of the mechanical properties of the rivet on the basis of the hardness profile in order to predict the correct deformation processes and stresses during the riveting process. First, the detailed experimental hardness mapping of the locally heat-treated rivets is transferred into the FE model. The FEM material model can predict the local strength of the rivet based on hardness by scaling the flow curves. To estimate the predictive capability of the FEM model, the joint formation of rivets with different graded hardness profiles is compared experimentally and simulative. Based on the validated model, the influence of different rivet hardness profiles on the joint formation is analysed numerically. By adapting the material model, a high level of correlation between the experiment's joint formation and the simulation can be achieved.","lang":"eng"}],"publication":"Materials Research Proceedings"},{"has_accepted_license":"1","status":"public","conference":{"start_date":"2025-11-27","name":"43.

These, however, are unable to detect phenomena immediately during the joining process. For instance, elastic deformations reverse and cracks close after unloading. In situ methods such as the force-displacement evaluation are used to investigate a clinching process, though deviations in the clinch point geometry cannot be derived with this method. To overcome these limitations, the clinching process can be investigated using in situ computed tomography (in situ CT). When investigating the clinching of aluminum parts in in situ CT, the sheet-sheet interface is hardly visible. Earlier investigations showed that radiopaque materials can be applied between the joining parts to enhance the detectability of the sheet-sheet interface. However, the layers cause strong artefacts, break during the clinching process or change the clinch joint’s properties significantly. In this paper, a minimally invasive method to enhance the interface detectability is presented. First, the aluminum oxide layer is removed by etching. Second, the specimen is electroplated with copper or gold, respectively. In some cases, a mask is applied to create a cross-shaped plating pattern. Then, the plated specimen is clinched with a non-plated counterpart and the interface detectability of the clinch points is assessed in CT scans. It is shown that a copper plating of 2.6–4 μm can visualize some parts of the interface, while 7–9 μm is suitable to enhance the detectability of the sheet-sheet interface almost continuously.</jats:p>","lang":"eng"}]},{"date_updated":"2026-02-26T09:05:06Z","title":"Die Möglichkeiten der Filament Extension Atomization ","year":"2025","status":"public","author":[{"first_name":"Moritz","orcid":"0000-0001-9101-8828","last_name":"Neukötter","full_name":"Neukötter, Moritz","id":"45530"},{"id":"3959","full_name":"Jesinghausen, Steffen","orcid":"https://orcid.org/0000-0003-2611-5298","last_name":"Jesinghausen","first_name":"Steffen"},{"last_name":"Schmid","orcid":"000-0001-8590-1921","first_name":"Hans-Joachim","full_name":"Schmid, Hans-Joachim","id":"464"}],"conference":{"name":"Jahrestreffen DECHEMA/VDI-Fachgruppe Mehrphasenströmung","start_date":"2025-03-19","location":"Hamburg","end_date":"2025-03-21"},"user_id":"45530","_id":"64658","language":[{"iso":"eng"}],"citation":{"chicago":"Neukötter, Moritz, Steffen Jesinghausen, and Hans-Joachim Schmid. “Die Möglichkeiten Der Filament Extension Atomization ,” 2025.","short":"M.

Accurate Finite Element Modeling (FEM) of joints is essential in the design of complex mechanical systems such as automotive body-in-white (BIW) structures, as it plays a critical role in evaluating their performance. Although well-established techniques exist for modeling rotationally symmetric joints, there remains a significant gap in effectively modeling non-rotationally symmetric joints. These joints are particularly relevant in the automotive BIW, where they can better accommodate anisotropic loading conditions. In this study, strategies for modeling non-rotationally symmetric joints were explored using finite element simulations in LS-DYNA. The findings demonstrate that discrete beam elements can capture the anisotropic characteristics of such joints. Two models were tested: a single-beam model for stiffness periodicity every 90°, and a three-beam model for stiffness periodicity every 120°. Force responses, stress distribution, and sheet bending behaviors were analyzed, confirming that discrete beam elements can accurately represent direction-dependent stiffness. These results establish a foundation for developing advanced joint modeling strategies in complex mechanical systems.</jats:p>","lang":"eng"}],"publication":"Materials Research Proceedings","type":"conference","department":[{"_id":"149"},{"_id":"9"},{"_id":"321"}],"date_created":"2025-04-08T14:57:51Z"}]
