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"}],"user_id":"7850"},{"type":"journal_article","year":"2022","citation":{"ama":"Popp J, Römisch D, Merklein M, 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.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.3390/app12104962","date_updated":"2022-12-05T21:49:30Z","project":[{"_id":"130","grant_number":"418701707","name":"TRR 285: TRR 285"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"145","name":"TRR 285 – C01: TRR 285 - Subproject C01"}],"publication_identifier":{"issn":["2076-3417"]},"publication_status":"published","title":"Joining of CFRT/Steel Hybrid Parts via Direct Pressing of Cold Formed Non-Rotational Symmetric Pin Structures"},{"title":"Joining Processes for Fibre-Reinforced Thermoplastics: Phenomena and Characterisation","project":[{"grant_number":"418701707","name":"TRR 285: TRR 285","_id":"130"},{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"name":"TRR 285 – A03: TRR 285 - Subproject A03","_id":"137"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"148","name":"TRR 285 – C04: TRR 285 - Subproject C04"}],"publication_status":"published","publication_identifier":{"issn":["1996-1944"]},"doi":"10.3390/ma15155454","date_updated":"2022-12-05T21:54:09Z","language":[{"iso":"eng"}],"user_id":"7850","abstract":[{"text":"Thermoplastic composites (TPCs) are predestined for use in lightweight structures, especially for high-volume applications. In many cases, joining is a key factor for the successful application of TPCs in multi-material systems. Many joining processes for this material group are based on warm forming the joining zone. 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. In order to identify the phenomena occurring in each process and to describe the characteristic resulting material structure in the joining zones, micrographs as well as computed tomography (CT) analyses are performed for both individual process stages and final joining zones.","lang":"eng"}],"date_created":"2022-12-05T21:51:47Z","status":"public","volume":15,"publication":"Materials","publisher":"MDPI AG","author":[{"first_name":"Juliane","full_name":"Troschitz, Juliane","last_name":"Troschitz"},{"last_name":"Gröger","first_name":"Benjamin","full_name":"Gröger, Benjamin"},{"last_name":"Würfel","first_name":"Veit","full_name":"Würfel, Veit"},{"full_name":"Kupfer, Robert","first_name":"Robert","last_name":"Kupfer"},{"last_name":"Gude","first_name":"Maik","full_name":"Gude, Maik"}],"issue":"15","article_number":"5454","intvolume":" 15","_id":"34225","year":"2022","type":"journal_article","citation":{"short":"J.

Hieraus resultieren durch höhere Prozesskräfte und Ultraschallleistung neueHerausforderungen bei der Prozessentwicklung; hierfür wird ein Simulationsmodell zur Verbesserungder Prozessentwicklung entwickelt.In Ultraschall-Drahtbondversuchen mit 400 m Aluminium und Kupfer Drähten wurde der Einflussder Prozessparameter auf die Bondqualität untersucht; diese Ergebnisse und zusätzliche Messungender Drahtdeformation und Schwingungen wurden für die Formulierung der Anforderungenund zur Validierung der Ergebnisse des Simulationsmodells genutzt.Es wurde ein Prozessmodell, basierend auf einer Co-Simulation zwischen MATLAB und ANSYS,entwickelt; hierbei wurden die phyiskalischen Phänomene wie die Ultraschall Werkstoffentfestigung,der Verbindungsaufbau und die dynamischen Systemeigenschaften abgebildet.Basierend auf einer Zug-Druck-Prüfmaschine wurde ein Prüfstand zur Identifikation der Modellparameterentwickelt. In zusätzlichen Druckversuchen mit den Bonddrähten mit und ohneUltraschallanregung wurde die Reduktion der Umformkräfte unter Ultraschalleinfluss untersucht.Mit dem entwickelten Prozessmodell wurden die Parameterstudien aus den Ultraschall-Drahtbondversuchensimuliert und direkt mit den experimentellen Ergebnissen verglichen, wobei sich einerelativ gute Übereinstimmung zwischen Simulation und Messung sowohl für Aluminium, als auchfür Kupfer, erzielen ließ.","lang":"ger"},{"lang":"eng","text":"Ultrasonic heavy wire bonding with aluminium wire is a standard process to produce electricalcontacts in power semiconductor modules. The increasing demands on the efficiency and reliabilityof the modules have led to technological developments and copper wires with significantlybetter electrical and thermal properties are used more often nowadays. This results in new challengesin process development due to higher process forces and ultrasonic power; for this purpose,a simulation model is developed to improve process development.Ultrasonic wire bonding tests with 400 m aluminium and copper wires were carried out to investigatethe influence of the process parameters on the bond quality; these results and additionalmeasurements of wire deformation and vibrations were used to define the requirements for themodel and validate the results of the simulation.A process model based on a co-simulation was developed between MATLAB and ANSYS; thephysical phenomena such as ultrasonic softening of the wire material, bond formation and dynamicbehaviour of the components were considered.Based on a tensile-compression testing machine, a test rig was developed to identify the modelparameters. In additional compression tests with the wires with and without ultrasonic excitation,the reduction of the forming forces under ultrasonic influence was characterised.With the developed process model, the parameter studies from the ultrasonic wire bond testswere simulated and directly compared with the experimental results; a relative good agreementbetween simulation and measurement could be achieved for both aluminium and copper."}],"user_id":"210"},{"language":[{"iso":"eng"}],"doi":"10.5465/ambpp.2022.16394abstract","date_updated":"2022-12-08T08:18:10Z","publication_identifier":{"issn":["0065-0668","2151-6561"]},"publication_status":"published","department":[{"_id":"178"},{"_id":"184"}],"title":"Speaking of Performance: Evaluating Team Members’ Performance with Open-Ended Audio Comments","type":"journal_article","citation":{"apa":"Gutt, J.
