An integrated securing of the joinability in versatile process chains is currently hardly possible as the number of combinable tool variants as well as variable force- and path-based process parameters is infinite. A versatile process chain, i.e. a sequence of all the processes and process steps required for product manufacturing, enables targeted changes to the semi-finished product, the joint, the component or the joining process that exceed the originally planned extend while still ensuring joinability. In detail, it leads to a unique joint with its own mechanical property profile, which, against the background of the resulting infinite number of combinations, makes it impossible to secure the joinability on the conventional experimentally based approach without extensive safety factors. The Transregional Colaborative Research Center 285 (TCRC285), which also initiated this special issue, is intended to enable mechanical joining technology to be versatile in the sense of high application flexibility. This is to be achieved with a numerical representation of the complete process chain from the incoming semi finished product via the joining part production and the joining process to the property profile of the joint in the operating phase. Thus a predictability of the joinability can be achieved and improvements in the individual life cycles of a joint can be realized by grasping the cause-and-effect relationships. On the basis of this knowledge, new possibilities for intervention in the joining process are to be created for the adaptation of the joining processes. With the aid of the methods developed for this purpose, tools will later be available to the end user to substitute the large number of mechanical joining processes or joining task-specific configurations with a smaller number of adaptable processes. This expands the flexibility in material choices, enabling challenges in environmental issues and sustainability to be overcome.}}, author = {{Meschut, Gerson and Merklein, Marion and Brosius, Alexander and Bobbert, Mathias}}, issn = {{0944-6524}}, journal = {{Production Engineering}}, keywords = {{Industrial and Manufacturing Engineering, Mechanical Engineering}}, number = {{2-3}}, pages = {{187--191}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Mechanical joining in versatile process chains}}}, doi = {{10.1007/s11740-022-01125-y}}, volume = {{16}}, year = {{2022}}, } @article{43155, author = {{Schmolke, Tobias and Meschut, Gerson and Meinderink, Dennis and Rieker, Florian and Grundmeier, Guido}}, issn = {{1619-1919}}, journal = {{adhäsion KLEBEN & DICHTEN}}, keywords = {{Polymers and Plastics, General Chemical Engineering, General Chemistry}}, number = {{6}}, pages = {{40--43}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Untersuchung von Klebverbindungen für Batteriegehäuse}}}, doi = {{10.1007/s35145-022-0596-9}}, volume = {{66}}, year = {{2022}}, } @article{43157, author = {{Werner, Matthias and Wagner, Jonas and Ribbeck, Florian and Hensel, Simon and Goth, Klaus and Graf, Thomas and Meschut, Gerson}}, issn = {{2212-8271}}, journal = {{Procedia CIRP}}, keywords = {{General Medicine}}, pages = {{513--517}}, publisher = {{Elsevier BV}}, title = {{{Influence of the incident angle on the OCT measurement during remote laser beam welding}}}, doi = {{10.1016/j.procir.2022.08.081}}, volume = {{111}}, year = {{2022}}, } @inproceedings{36871, abstract = {{Additive manufacturing offers the option of converting digital prototypes into real structures as quickly as possible by the special property of tool-free manufacturing.

In addition to the extrusion of decking boards, the material is also used increasingly in injection molding. Depending on the formulation, geometry and process parameters, WPC tends to exhibit irregular filling behavior, similar to the processing of thermosets. In this work, the influence of matrix material and wood fiber content on the flow, mold filling and segregation behavior of WPC is analyzed. For this purpose, investigations were carried out on a flow spiral and a sheet cavity. WPC based on thermoplastic polyurethane (TPU) achieves significantly higher flow path lengths at a wood mass content of 30% than polypropylene (PP)-based WPC. The opposite behavior occurs at higher wood contents due to the different shear thinning behavior. Slightly decreased wood contents could be observed at the beginning of the flow path and greatly increased wood contents at the end of the flow path, compared to the starting material. When using the plate cavity, flow anomalies in the form of free jets occur as a function of the wood content, with TPU exhibiting the more critical behavior. The flow front is frayed, but in contrast to the flow spiral, no significant wood accumulation could be detected due to the shorter flow path lengths.}}, author = {{Moritzer, Elmar and Flachmann, Felix and Richters, Maximilian and Neugebauer, Marcel}}, issn = {{2504-477X}}, journal = {{Journal of Composites Science}}, keywords = {{Engineering (miscellaneous), Ceramics and Composites}}, number = {{10}}, publisher = {{MDPI AG}}, title = {{{Analysis of the Segregation Phenomena of Wood Fiber Reinforced Plastics}}}, doi = {{10.3390/jcs6100321}}, volume = {{6}}, year = {{2022}}, } @article{33477, author = {{Bothe, Mike and Hami Dindar, Iman and Lutters, Nicole and Kenig, Eugeny Y.}}, journal = {{Computers and Chemical Engineering}}, publisher = {{Elsevier}}, title = {{{Dynamic modeling of absorption/desorption closed-loop including periphery}}}, year = {{2022}}, } @article{34241, abstract = {{Due to the increasing use of multi-material constructions and the resulting material incompatibilities, mechanical joining technologies are gaining in importance. The reasons for this are the variety of joining possibilities as well as high load-bearing capacities. However, the currently rigid tooling systems cannot react to changing boundary conditions, such as changed sheet thicknesses or strength. For this reason, a large number of specialised joining processes have been developed to expand the range of applications. Using a versatile self-piercing riveting process, multi-material structures are joined in this paper. In this process, a modified tool actuator technology is combined with multi-range capable auxiliary joining parts. The multi-range capability of the rivets is achieved by forming the rivet head onto the respective thickness of the joining part combination without creating a tooling set-up effort. The joints are investigated both experimentally on the basis of joint formation and load-bearing capacity tests as well as by means of numerical simulation. It turned out that all the joints examined could be manufactured according to the defined standards. The load-bearing capacities of the joints are comparable to those of conventionally joined joints. In some cases the joint fails prematurely, which is why lower energy absorptions are obtained. However, the maximum forces achieved are higher than those of conventional joints. Especially in the case of high-strength materials arranged on the die side, the interlock formation is low. In addition, the use of die-sided sheets requires a large deformation of the rivet head protrusion, which leads to an increase in stress and, as a result, to damage if the rivet head. However, a negative influence on the joint load-bearing capacity could be excluded.}}, author = {{Kappe, Fabian and Wituschek, Simon and Bobbert, Mathias and Lechner, Michael and Meschut, Gerson}}, issn = {{0944-6524}}, journal = {{Production Engineering}}, keywords = {{Industrial and Manufacturing Engineering, Mechanical Engineering}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Joining of multi-material structures using a versatile self-piercing riveting process}}}, doi = {{10.1007/s11740-022-01151-w}}, year = {{2022}}, } @article{30100, abstract = {{Since the application of mechanical joining methods, such as clinching or riveting, offers a robust solution for the generation of advanced multi-material connections, the use in the field of lightweight designs (e.g. automotive industry) is steadily increasing. Therefore, not only the design of an individual joint is required but also the dimensioning of the entire joining connection is crucial. However, in comparison to thermal joining techniques, such as spot welding, the evaluation of the joints’ resistance against defined requirements (e.g. types of load, minimal amount of load cycles) mainly relies on the consideration of expert knowledge, a few design principles and a small amount of experimental data. Since this generally implies the involvement of several domains, such as the material characterization or the part design, a tremendous amount of data and knowledge is separately generated for a certain dimensioning process. Nevertheless, the lack of formalization and standardization in representing the gained knowledge leads to a difficult and inconsistent reuse, sharing or searching of already existing information.
