The high-speed joining process (also called “RIVTAC®” or “Impact”) is an innovative and flexible technology. In this process, a tack having a profiled shank and an ogival shaped tip is pushed into the joining partners with a speed of 20 to 40 m/s without any pre-punching. The plastic and friction work is converted into heat, which causes an abrupt rise of temperature in the joining zone. This improves the flowability of the material which leads to filling the annular grooves existing on the shank of the tack. Simultaneously, a force-fit is created between the sheet metal and the tack. Furthermore, the effects of inertia are used so that the thin-walled structures can be joined without any additional tools (e.g. a die). The joining process causes the deformation of the structure, which must be taken into account with regard to tolerances. The numerical simulation is a powerful tool to predict the deformation and the joinability of a complex structure as well as the mechanical properties of the connection. The paper is about the detailed process- and load-simulation of high-speed joining as well as the required experimental data basis, such as temperature and strain rate dependent flow curves. Furthermore, the friction parameters are very important for the physical consideration of the force-fit connection. Coupled structural-thermal simulations of an axisymmetric 2D-model are performed using explicit and implicit codes.}}, author = {{Meschut, Gerson and Hein, David and Gerkens, Michael}}, issn = {{2351-9789}}, journal = {{Procedia Manufacturing}}, pages = {{280--287}}, publisher = {{Elsevier BV}}, title = {{{Numerical simulation of high-speed joining of sheet metal structures}}}, doi = {{10.1016/j.promfg.2019.02.173}}, volume = {{29}}, year = {{2019}}, } @article{19747, author = {{Ditter, Jan and Meschut, Gerson and Wibbeke, Tim Michael}}, journal = {{Adhäsion Kleben&Dichten}}, number = {{6}}, pages = {{18--24}}, title = {{{Disjoining and joining concepts for adhesive-bonded lightweight structures}}}, doi = {{10.1007/s35145-019-0038-5}}, year = {{2019}}, } @article{19742, author = {{Ditter, Jan and Wünsche, Marc and Meschut, Gerson and Wibbeke, Tim Michael}}, issn = {{0043-2288}}, journal = {{Welding in the World}}, pages = {{237--247}}, title = {{{Mechanical properties of repair welded joints for automobile body structures}}}, doi = {{10.1007/s40194-018-0651-1}}, year = {{2018}}, } @inproceedings{19754, author = {{Ditter, Jan and Meschut, Gerson}}, editor = {{da Silva, Lucas}}, location = {{Lissabon}}, title = {{{Qualification of Fast Curing Processes for Elementary Bonded Structures}}}, year = {{2018}}, } @misc{19898, author = {{Vorderbrüggen, Julian and Meschut, Gerson and Augenthaler, Florian and Ditz, Michael and Günter, Heinrich and Schmal, Christopher}}, booktitle = {{Jahresmagazin Werkstofftechnik}}, title = {{{Fügetechnik: Schlüsseltechnologie für ressourceneffiziente Hochleistungsverbundsysteme}}}, year = {{2018}}, } @inproceedings{20263, author = {{Göddecke, Johannes and Meschut, Gerson and Teutenberg, Dominik}}, booktitle = {{12TH EUROPEAN ADHESION CONFERENCE (EURADH 2018)}}, editor = {{da Silva, Lucas}}, isbn = {{978-989-8927-24-8}}, location = {{Lissabon}}, title = {{{Constructive design of bonded FRP mixed joints under consideration of edge effects}}}, year = {{2018}}, } @book{20267, author = {{Göddecke, Johannes and Meschut, Gerson}}, isbn = {{978-3-86780-559-9}}, publisher = {{Plattform FOREL}}, title = {{{FOREL-Studie 2018: Ressourceneffizienter Leichtbau für die Mobilität (Wandel-Prognose-Transfer)}}}, year = {{2018}}, } @article{20282, abstract = {{Modern developments in the automotive sector are motivated by the objective of lowering the emission of pollutants. In contrast, growing demands for safety and comfort lead to a potential increase of the weight of vehicles. Thus, the consequent use of lightweight design is indispensable. This includes the use of different materials for the construction of car bodies. Because of various material properties, joining of dissimilar materials is challenging and requires often the application of non-thermic processes like riveting or clinching. These processes are limited by the mechanical properties of the joining partners. Especially the increasing use of ultra-high strength alloys, like the hot stamped steel 22MnB5, makes the development of new joining technologies necessary. One of these innovative technologies is shear-clinching. By combining shear-cutting and clinching in one process, this technology produces durable and tight connections of dissimilar materials with high differences regarding strength and formability. In contrast to shear-cutting the die-sided material has no contact with the punch. Since the process of shear-clinching is a combination of cutting and joining using the same tool, the tool loads differ from common shear-cutting. Especially cutting hot stamped steels is a challenge due to their high ultimate strength which leads to high tool loads. Thus, the analysis of the load condition is essential for the dimensioning of durable and wear resistant tools. Hence, the scope of this paper is a numerical investigation of the tool loads during the indirect cutting process and the subsequent step of joining by forming during shear-clinching. Since an experimental investigation of the occurring tool loads in the closed process is not practicable, the finite element method has to be used. Therefore, a damage-based numerical model is set up to enable the coupled simulation of the combined cutting and joining process and the resulting tool loads. This allows the analysis of the loads during the whole process, identifying the influences of materials and sheet thicknesses.}}, author = {{Wiesenmayer, Sebastian and Müller, Martin and Dornberger, Peter and Han, Daxin and Hörhold, Réjane and Meschut, Gerson and Merklein, Marion}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, pages = {{397--404}}, title = {{{Numerical Investigation of the Tool Load in Joining by Forming of Dissimilar Materials Using Shear-Clinching Technology}}}, doi = {{10.4028/www.scientific.net/kem.767.397}}, year = {{2018}}, } @article{20283, author = {{Han, Daxin and Hörhold, Réjane and Wiesenmayer, Sebastian and Merklein, Marion and Meschut, Gerson}}, issn = {{2351-9789}}, journal = {{Procedia Manufacturing}}, pages = {{1346--1353}}, title = {{{Investigation of the influence of tool-sided parameters on deformation and occurring tool loads in shear-clinching processes}}}, doi = {{10.1016/j.promfg.2018.07.349}}, year = {{2018}}, } @article{20289, author = {{Ivanjko, Martin and Meschut, Gerson}}, issn = {{0043-2288}}, journal = {{Welding in the World}}, pages = {{97--106}}, title = {{{Innovative joining technology for multi-material applications with high manganese steels in lightweight car body structures}}}, doi = {{10.1007/s40194-018-0648-9}}, year = {{2018}}, } @inproceedings{20298, author = {{Günter, Heinrich and Meschut, Gerson}}, booktitle = {{Tagungsband zum 8.
