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."}],"status":"public","type":"journal_article","publication":"Advanced Engineering Materials","title":"Mechanical Properties and Joinability of AlSi9 Alloy Manufactured by Twin‐Roll Casting","doi":"10.1002/adem.202200874","date_updated":"2022-12-05T20:09:50Z","publisher":"Wiley","date_created":"2022-12-05T20:07:55Z","author":[{"first_name":"Moritz","full_name":"Neuser, Moritz","last_name":"Neuser"},{"first_name":"Fabian","full_name":"Kappe, Fabian","last_name":"Kappe"},{"first_name":"Jakob","full_name":"Ostermeier, Jakob","last_name":"Ostermeier"},{"first_name":"Jan Tobias","full_name":"Krüger, Jan Tobias","last_name":"Krüger"},{"first_name":"Mathias","full_name":"Bobbert, Mathias","last_name":"Bobbert"},{"last_name":"Meschut","full_name":"Meschut, Gerson","first_name":"Gerson"},{"first_name":"Mirko","full_name":"Schaper, Mirko","last_name":"Schaper"},{"last_name":"Grydin","full_name":"Grydin, Olexandr","first_name":"Olexandr"}],"volume":24,"year":"2022","citation":{"ama":"Neuser M, Kappe F, Ostermeier J, et al.

This leads to advantages such as reduced joining time and manufacturing\r\ncosts. On the other hand, the joint strength solely relies on directed material deformation, which renders an accurate material modelling essential to reliably predict the joint forming. The formation of the joint locally involves large plastic strains and possibly complex non-proportional loading paths, as typical of many metal forming applications. Consequently, a finite plasticity formulation is utilised incorporating a Chaboche–Rousselier kinematic hardening law to capture the Bauschinger effect. Material parameters are identified from tension–compression tests on miniature spec-\r\nimens for the dual-phase steel HCT590X. The resulting material model is implemented in LS-Dyna to study the locally diverse loading paths and give a quantitative statement on the importance of kinematic hardening for clinching. It turns out that the Bauschinger effect mainly affects the springback of the sheets and has a smaller effect on the joint forming itself.","lang":"eng"}],"status":"public","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"_id":"139","name":"TRR 285 – A05: TRR 285 - Subproject A05"}],"_id":"34211","user_id":"7850","keyword":["Clinching","Material modelling","Kinematic hardening","Parameter identification","Bauschinger effect"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"isbn":["9783031062117","9783031062124"],"issn":["2367-1181","2367-1696"]},"year":"2022","place":"Cham","citation":{"apa":"Friedlein, J., Mergheim, J., &#38; Steinmann, P.

In this paper, the potential of the in situ investigation of a clinching process as validation method is analyzed. For the in situ testing, a tailored test set-up featuring a beryllium cylinder for load-bearing and clinching tools made from ultra-high-strength titanium and Si3N4 are used. In the experiments, the clinching of two aluminum sheets is interrupted at specific process steps in order to perform the CT scans. It is shown that in situ CT visualizes the inner geometry of the joint at high precision and that this method is suitable to validate numerical models.","lang":"eng"}],"status":"public","publication":"The Minerals, Metals & Materials Series","type":"book_chapter","keyword":["Clinching","Non-destructive testing","Computed tomography","In situ CT"],"language":[{"iso":"eng"}],"_id":"34212","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"148","name":"TRR 285 – C04: TRR 285 - Subproject C04"}],"user_id":"7850","place":"Cham","year":"2022","citation":{"ieee":"D.

For this reason, multi-material-systems made of high-strength steel and aluminium as well as metal and fibre-reinforced plastics gain in importance. However, different material properties, e.g. stiffness, thermal expansion coefficients or chemical incompatibilities, are challenging for conventional joining technologies. Joining by cold formed pin structures has shown to have high potential for joining multi-material-systems. These pins can be joined either by direct pin pressing into an unperforated joining partner or by caulking, where the pins are inserted through a pre-punched joining partner and the pin head is upset, resulting in a form-fit joint. Usually, cylindrical pins are used for joining. However, non-rotationally symmetrical pin geometries offer the possibility of introducing a predetermined breaking point or reinforcing a connection in the principal force direction. In this work, cylindrical pins as well as non-rotationally symmetrical pin geometries, such as polygonal and oval pin structures, are cold extruded from the sheet metal plane of an HCT590X+Z dual phase steel and joined in the next step with an EN AW-6014 aluminium using direct pin pressing. Since the formation of an undercut has an crucial influence on the joint strength, the investigations will be focused on the resulting joint geometry. In addition, the effect of different pin heights will be examined to analyse the joint formation at different levels of compression of the pin structures. Finally, the joints are evaluated regarding their joint strength in tensile shear tests and cross tension tests. Here the flow resistance of the geometry used as well as the pin height and thus the strain hardening of the pin base during the extrusion of the pins play a decisive role for the shear strength.","lang":"eng"}],"status":"public"},{"title":"Joining of CFRT/Steel Hybrid Parts via Direct Pressing of Cold Formed Non-Rotational Symmetric Pin Structures","doi":"10.3390/app12104962","publisher":"MDPI AG","date_updated":"2022-12-05T21:49:30Z","volume":12,"author":[{"full_name":"Popp, Julian","last_name":"Popp","first_name":"Julian"},{"first_name":"David","full_name":"Römisch, David","last_name":"Römisch"},{"last_name":"Merklein","full_name":"Merklein, Marion","first_name":"Marion"},{"last_name":"Drummer","full_name":"Drummer, Dietmar","first_name":"Dietmar"}],"date_created":"2022-12-05T21:48:01Z","year":"2022","intvolume":"        12","citation":{"apa":"Popp, J., Römisch, D., Merklein, M., &#38; Drummer, D.

In comparison to already available studies, the unique novelty is the use of non-rotational symmetric pin structures for the CFRT/metal hybrid joining. Thus, a variation in the fiber orientation in the CFRT component as well as a variation in the non-rotational symmetric pins’ orientation in relation to the sample orientation is conducted. The created samples are consequently mechanically tested via single lap shear experiments in a quasi-static state. Finally, the failure behavior of the single lap shear samples is investigated with the help of microscopic images and detailed photographs. In the single lap shear tests, it could be shown that non-rotational symmetric pin structures lead to an increase in maximum testing forces of up to 74% when compared to cylindrical pins. However, when normalized to the pin foot print related joint strength, only one polygonal pin variation showed increased joint strength in comparison to cylindrical pin structures. The investigation of the failure behavior showed two distinct failure modes. The first failure mode was failure of the CFRT component due to an exceedance of the maximum bearing strength of the pin-hole leading to significant damage in the CFRT component. The second failure mode was pin-deflection due to the applied testing load and a subsequent pin extraction from the CFRT component resulting in significantly less visible damage in the CFRT component. Generally, CFRT failure is more likely with a fiber orientation of 0° in relation to the load direction while pin extraction typically occurs with a fiber orientation of 90°. It is assumed that for future investigations, pin structures with an undercutting shape that creates an interlocking joint could counteract the tendency for pin-extraction and consequently lead to increased maximum joint strengths."}],"status":"public","publication":"Applied Sciences","type":"journal_article"},{"type":"journal_article","publication":"Materials","abstract":[{"lang":"eng","text":"Thermoplastic composites (TPCs) are predestined for use in lightweight structures, especially for high-volume applications.

This results in a change of the local material structure characterised by modified fibre paths, as well as varying fibre contents, which significantly influences the load-bearing behaviour. During the forming process, many different phenomena occur simultaneously at different scales. In this paper, the deformation modes and flow mechanisms of TPCs during forming described in the literature are first analysed. Based on this, three different joining processes are investigated: embedding of inserts, moulding of contour joints, and hotclinching.

Here we provide microscopic insights into this process by monitoring the dissipation of energy in salt solutions using time-resolved terahertz–Raman spectroscopy. We resonantly drive the low-frequency rotational dynamics of water molecules using intense terahertz pulses and probe the Raman response of their intermolecular translational motions. We find that the intermolecular rotational-to-translational energy transfer is enhanced by highly charged cations and is drastically reduced by highly charged anions, scaling with the ion surface charge density and ion concentration. Our molecular dynamics simulations reveal that the water–water hydrogen-bond strength between the first and second solvation shells of cations increases, while it decreases around anions. The opposite effects of cations and anions on the intermolecular interactions of water resemble the effects of ions on the stabilization and denaturation of proteins.</jats:p>","lang":"eng"}]},{"status":"public","abstract":[{"text":"Wie werden technische Systeme zeitgemäß entwickelt, die in Komplexität und Anspruch alles bisher Dagewesene übertreffen?

However, to ensure a sufficient reliability of the product design, not only the selection of an appropriate manufacturing and joining method, but also the suitable dimensioning and validation of the entire joining process is a crucial step. In this context, thermal processes offer a large number of design principles while mechanical joining methods mainly require extensive experimental tests and the inclusion of expert knowledge. Although few contributions already investigated the data-based analysis of mechanical joints, a system for the requirement- and manufacturing-oriented dimensioning of joining components, such as different profiles and blanks, in combination with the estimation of joint properties is not available yet. Motivated by this lack, this contribution introduces an engineering workbench for the support of design engineers in the early development phases of the knowledge and data-based design of mechanical joining connections using clinching as an example. In this regard, the approach is demonstrated involving a similar material and sheet thickness combination with static loads.","lang":"eng"}],"user_id":"7850","_id":"34415","project":[{"_id":"130","name":"TRR 285: TRR 285","grant_number":"418701707"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B05: TRR 285 - Subproject B05","_id":"144"}],"language":[{"iso":"eng"}],"publication_status":"published","citation":{"chicago":"Zirngibl, Christoph, Christopher Sauer, Benjamin Schleich, and Sandro Wartzack. “Knowledge and Data-Based Design and Dimensioning of Mechanical Joining Connections.” In <i>Volume 2: 42nd Computers and Information in Engineering Conference (CIE)</i>.
