These are frequently applied in the form of multi-material systems, which are characterized by the selective use of materials and geometries. One major challenge in the manufacturing of multi-material systems is the joining of the individual components to form a complete system. Mechanical joining processes such as semi-tubular self-piercing riveting are frequently used for this application but reach their limits concerning the number of combinations of geometry and material. In order to react to the requirements and to increase the versatility of semi-tubular self-pierce riveting, a process combination consisting of a tumbling process and a self-pierce riveting process has been presented previously. This process combination is used in this work to investigate the versatility and to identify the influencing parameters on it. For this purpose, experiments are conducted to identify process-side influence possibilities. The tests are performed with a dual-phase steel aluminum alloy to represent the varying mechanical characteristics of multi-material systems. Furthermore, the initial sheet thicknesses of the joining partners are varied in several steps. In addition to the geometric joint formation used to describe the undercut, the rivet head end position and the residual sheet thickness, the joining process, is also analyzed during the investigations. Further, the innovative joining process is evaluated by comparing it with a conventional self-piercing riveting process. The knowledge obtained represents a basis for the identification and evaluation of the versatility of the process combination.","lang":"eng"}],"date_created":"2023-03-29T08:36:26Z","author":[{"last_name":"Wituschek","full_name":"Wituschek, Simon","first_name":"Simon"},{"first_name":"Fabian","full_name":"Kappe, Fabian","last_name":"Kappe"},{"first_name":"Gerson","last_name":"Meschut","full_name":"Meschut, Gerson"},{"full_name":"Lechner, Michael","last_name":"Lechner","first_name":"Michael"}],"publisher":"SAGE Publications","date_updated":"2023-03-29T08:36:59Z","doi":"10.1177/14644207221135400","title":"Geometric and mechanical joint characterization of conventionally and tumbled self-piercing riveting joints","publication_status":"published","publication_identifier":{"issn":["1464-4207","2041-3076"]},"citation":{"apa":"Wituschek, S., Kappe, F., Meschut, G., & Lechner, M.

In this work, the formation of (defect) bound polarons in lithium niobate is studied by ab initio molecular dynamics. The calculations show a broad scatter of polaron formation times. Rising temperature increases the share of trajectories with long formation times, which leads to an overall increase of the average formation time with temperature. However, even at elevated temperatures, the average formation time does not exceed the value of 100 femtoseconds, i.e., a value close to the time measured for free, i.e., self-trapped polarons. Analyzing individual trajectories, it is found that the time required for the structural relaxation of the polarons depends sensitively on the excitation of the lithium niobate high-frequency phonon modes and their phase relation.","lang":"eng"}],"type":"journal_article","publication":"Applied Physics A","language":[{"iso":"eng"}],"keyword":["General Materials Science","General Chemistry"],"user_id":"171","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"230"},{"_id":"429"},{"_id":"35"},{"_id":"790"}],"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"name":"TRR 142: TRR 142","_id":"53"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - A: TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - A11: TRR 142 - Subproject A11","_id":"166"},{"name":"TRR 142 - B07: TRR 142 - Subproject B07","_id":"168"}],"_id":"37711","citation":{"ama":"Krenz M, Gerstmann U, Schmidt WG.

These are frequently applied in the form of multi-material systems, which are characterized by the selective use of materials and geometries. One major challenge in the manufacturing of multi-material systems is the joining of the individual components to form a complete system. Mechanical joining processes such as semi-tubular self-piercing riveting are frequently used for this application but reach their limits concerning the number of combinations of geometry and material. In order to react to the requirements and to increase the versatility of semi-tubular self-pierce riveting, a process combination consisting of a tumbling process and a self-pierce riveting process has been presented previously. This process combination is used in this work to investigate the versatility and to identify the influencing parameters on it. For this purpose, experiments are conducted to identify process-side influence possibilities. The tests are performed with a dual-phase steel aluminum alloy to represent the varying mechanical characteristics of multi-material systems. Furthermore, the initial sheet thicknesses of the joining partners are varied in several steps. In addition to the geometric joint formation used to describe the undercut, the rivet head end position and the residual sheet thickness, the joining process, is also analyzed during the investigations. Further, the innovative joining process is evaluated by comparing it with a conventional self-piercing riveting process. The knowledge obtained represents a basis for the identification and evaluation of the versatility of the process combination.

In addition to experimental investigations, numerical studies are indispensable tools for its development. Therefore, this paper includes an analysis of boundary conditions for the spatial discretization and mesh modeling techniques, the material modeling, the contact and friction modeling, and the thermal boundary conditions for the finite element (FE) modeling of this joining process. For these investigations, two FE models corresponding to the two process steps were set up and compared with the two related processes of friction stir welding and friction drilling. Regarding the spatial discretization, the Lagrangian approach is not sufficient to represent the deformation that occurs. The Johnson-Cook model is well suited as a material model. The modeling of the contact detection and friction are important research subjects. Coulomb’s law of friction is not adequate to account for the complex friction phenomena of the adaptive joining process. The thermal boundary conditions play a decisive role in heat generation and thus in the material flow of the process. It is advisable to use temperature-dependent parameters and to investigate in detail the influence of radiation in the entire process.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["General Materials Science","Metals and Alloys"],"issue":"5","quality_controlled":"1","year":"2022","date_created":"2022-05-21T17:27:16Z","publisher":"MDPI AG","title":"Identification of Requirements for FE Modeling of an Adaptive Joining Technology Employing Friction-Spun Joint Connectors (FSJC)","type":"journal_article","status":"public","user_id":"83141","department":[{"_id":"9"},{"_id":"156"},{"_id":"630"}],"project":[{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C03: TRR 285 - Subproject C03","_id":"147"},{"_id":"130","name":"TRR 285: TRR 285","grant_number":"418701707"}],"_id":"31360","article_number":"869","publication_status":"published","publication_identifier":{"issn":["2075-4701"]},"citation":{"apa":"Oesterwinter, A., Wischer, C., & Homberg, W.

They permit materials of different types to be joined in a way that is suitable for the loads involved. These processes reach their limits, however, as soon as the boundary conditions change. In most cases, these elements are specially adapted to the joining point and cannot be used universally. Changes require cost-intensive adaptation of both the element and the process control, thus making production more complex. This results in high costs due to the increased number of auxiliary joining element variants required and reduces the economic efficiency of mechanical joining. One approach to overcoming this issue is the use of adaptive auxiliary joining elements formed by friction spinning. This article presents the current state of research on pre-hole-free joining with adaptive joining elements. The overall process chain is illustrated, explained and analyzed. Special attention is paid to demonstrating the feasibility of pre-hole-free joining with adaptive joining elements. The chosen mechanical parameters are subsequently listed.

Adapcrack3D is a simulation program that can accurately predict the propagation of cracks in real structures. However, until now, this three-dimensional program has only considered mechanical loads and static thermal loads. Therefore, the features of Adapcrack3D have been extended by including contact loading in crack growth simulations. The numerical simulation of crack propagation with Adapcrack3D is generally carried out using FE models of structures provided by the user. For simulating models with contact loading situations, Adapcrack3D has been updated to work with FE models containing multiple parts and necessary features such as coupling and surface interactions. Because Adapcrack3D uses the submodel technique for fracture mechanical evaluations, the architecture of the submodel is also modified to simulate models with contact definitions between the crack surfaces. This paper discusses the newly implemented attribute of the program with the help of illustrative examples. The results confirm that the contact simulation in Adapcrack3D is a major step in improving the functionality of the program.","lang":"eng"}],"publication":"Applied Sciences","language":[{"iso":"eng"}],"keyword":["Fluid Flow and Transfer Processes","Computer Science Applications","Process Chemistry and Technology","General Engineering","Instrumentation","General Materials Science"]},{"citation":{"mla":"Kullmer, Gunter, et al. “Development of a Method for the Separate Measurement of the Growth of Internal Crack Tips by Means of the Potential Drop Method.” Engineering Fracture Mechanics, 108899, Elsevier BV, 2022, doi:10.1016/j.engfracmech.2022.108899.","bibtex":"@article{Kullmer_Weiß_Schramm_2022, title={Development of a method for the separate measurement of the growth of internal crack tips by means of the potential drop method}, DOI={10.1016/j.engfracmech.2022.108899}, number={108899}, journal={Engineering Fracture Mechanics}, publisher={Elsevier BV}, author={Kullmer, Gunter and Weiß, Deborah and Schramm, Britta}, year={2022} }","short":"G.

This paper presents a new tool and process design with a driven tool for the targeted adjustment of residual stress distributions in the friction-spinning process. Locally adapted residual stress depth distributions are intended to improve the functionality of the friction-spinning workpieces, e.g. by delaying failure or triggering it in a defined way. The new process designs with the driven tool and a subsequent flow-forming operation are investigated regarding the influence on the residual stress depth distributions compared to those of standard friction-spinning process. Residual stress depth distributions are measured with the incremental hole-drilling method. The workpieces (tubular part with a flange) are manufactured using heat-treatable 3.3206 (EN-AW 6060 T6) tubular profiles. It is shown that the residual stress depth distributions change significantly due to the new process designs, which offers new potentials for the targeted adjustment of residual stresses that serve to improve the workpiece properties."}],"publication":"Key Engineering Materials","language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"]}]
