@article{30695, abstract = {{Due to their cost-efficiency and environmental friendliness, the demand of mechanical joining processes is constantly rising. However, the dimensioning and design of joints and suitable processes are mainly based on expert knowledge and few experimental data. Therefore, the performance of numerical and experimental studies enables the generation of optimized joining geometries. However, the manual evaluation of the results of such studies is often highly time-consuming. As a novel solution, image segmentation and machine learning algorithm provide methods to automate the analysis process. Motivated by this, the paper presents an approach for the automated analysis of geometrical characteristics using clinching as an example. }}, author = {{Zirngibl, C. and Schleich, B.}}, journal = {{Key Engineering Materials}}, pages = {{105}}, title = {{{Approach for the automated analysis of geometrical clinch joint characteristics}}}, doi = {{10.4028/www.scientific.net/KEM.883.105}}, volume = {{883 KEM}}, year = {{2021}}, } @inproceedings{34472, author = {{Kullmer, Gunter and Weiß, Deborah and Schramm, Britta}}, location = {{Bremen}}, pages = {{107--116}}, title = {{{Entwicklung einer Methode zur differenzierten Messung des Wachstums der Rissenden von Innenrissen mit der Elektropotentialmethode}}}, doi = {{10.48447/BR-2021-013}}, volume = {{DVM-Bericht 253}}, year = {{2021}}, } @inproceedings{24006, author = {{Weiß, Deborah and Schramm, Britta and Neuser, Moritz and Grydin, Olexandr and Kullmer, Gunter}}, location = {{Bremen}}, pages = {{231--240}}, title = {{{Experimentelle bruchmechanische Untersuchung eines clinchgeeigneten Bleches aus HCT590X mithilfe einer neuen Probengeometrie}}}, doi = {{10.48447/BR-2021-025}}, volume = {{DVM-Bericht 253}}, year = {{2021}}, } @article{24541, abstract = {{The mechanical properties of joined structures are determined considerably by the chosen joining technology. With the aim of providing a method that enables a faster and more profound decision-making in the spatial distribution of joining points during product development, a new method for the load path analysis of joining points is presented. For an exemplary car body, the load type in the joining elements, i.e. pure tensile, shear and combined tensile-shear loads, is determined using finite element analysis (FEA). Based on the evaluated loads, the resulting load paths in selected joining points are analyzed using a 2D FE-model of a clinching point. State of the art methods for load path analysis are dependent on the selected coordinate system or the existing stress state. Thus, a general statement about the load transmission path is not possible at this time. Here, a novel method for the analysis of load paths is used, which is independent of the alignment of the analyzed geometry. The basic assumption of the new load path analysis method was confirmed by using a simple specimen with a square hole in different orientations. The results presented here show a possibility to display the load transmission path invariantly. In further steps, the method will be extended for 3D analysis and the investigation of more complex assemblies. The primary goal of this methodical approach is an even load distribution over the joining elements and the component. This will provide a basis for future design approaches aimed at reducing the number of joining elements in joined structures.}}, author = {{Steinfelder, Christian and Martin, Sven and Brosius, Alexander and Tröster, Thomas}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, pages = {{73--80}}, title = {{{Load Path Transmission in Joining Elements}}}, doi = {{10.4028/www.scientific.net/kem.883.73}}, year = {{2021}}, } @article{24548, author = {{Martin, Sven and Tröster, Thomas}}, journal = {{ESAFORM 2021}}, title = {{{Joint point loadings in car bodies – the influence of manufacturing tolerances and scatter in material properties}}}, doi = {{10.25518/esaform21.3801}}, year = {{2021}}, } @article{29293, author = {{Martin, Sven and Schütte, Jan and Bäumler, C. and Sextro, Walter and Tröster, Thomas}}, issn = {{2666-3597}}, journal = {{Forces in Mechanics}}, publisher = {{Elsevier BV}}, title = {{{Identification of joints for a load-adapted shape in a body in white using steady state vehicle simulations}}}, doi = {{10.1016/j.finmec.2021.100065}}, volume = {{6}}, year = {{2021}}, } @article{30706, author = {{Steinfelder, C. and Brosius, A.}}, journal = {{Lecture Notes in Production Engineering}}, pages = {{134--141}}, title = {{{A New Approach for the Evaluation of Component and Joint Loads Based on Load Path Analysis}}}, doi = {{10.1007/978-3-662-62138-7_14}}, year = {{2020}}, } @article{30711, author = {{Ewenz, L. and Schettler, S. and Zeuner, A.
