For this, two cellular solids having nested and non-nested structures are designed and additively manufactured via laser powder bed fusion. The primary objective is to design cellular solids which absorb a significant amount of energy upon impact loading without transmitting a high amount of stress into the cellular solids. Therefore, compression testing of the two cellular solids is performed. The nested and non-nested cellular solids show similar energy absorption properties; however, the nested cellular solid transmits a lower amount of stress in the cellular structure compared to the non-nested cellular solid. The experimentally measured strain (by DIC) in the interior region of the nested cellular solid is lower despite a higher value of externally imposed compressive strain. The second objective of this study is to determine the thermal insulation properties of cellular solids. For measuring the thermal insulation properties, the samples are placed on a hot plate; and the surface temperature distribution is measured by an infrared camera. The thermal insulating performance of both cellular types is sufficient for temperatures exceeding 100 °C. However, the thermal insulating performance of a non-nested cellular solid is slightly better than that of the nested cellular solid. Additional thermal simulations predict a relatively higher temperature distribution on the cellular solid surfaces compared to experimental results. The simulated residual stress shows a similar distribution for both types, but the magnitude of residual stress is different for the cellular solids upon cooling from different temperatures of the hot plate.","lang":"eng"}],"publication":"Crystals","type":"journal_article","doi":"10.3390/cryst12091217","title":"Additively Manufactured Nested and Non-Nested Cellular Solids for Effective Stress Distribution and Thermal Insulation Applications: An Experimental and Finite Element Analysis Study","volume":12,"date_created":"2023-02-02T14:22:59Z","author":[{"last_name":"Pramanik","full_name":"Pramanik, Sudipta","first_name":"Sudipta"},{"full_name":"Milaege, Dennis","last_name":"Milaege","first_name":"Dennis"},{"first_name":"Kay-Peter","full_name":"Hoyer, Kay-Peter","last_name":"Hoyer"},{"last_name":"Schaper","full_name":"Schaper, Mirko","first_name":"Mirko"}],"publisher":"MDPI AG","date_updated":"2023-04-27T16:48:04Z","intvolume":" 12","citation":{"ieee":"S.

The most common way to characterize the additively manufactured lattice structures is via the uniaxial compression test. However, although there are many applications for which lattice structures are designed for bending (e.g., sandwich panels cores and some medical implants), limited attention has been paid toward investigating the flexural behavior of metallic AM lattice structures with tunable internal architectures. The purpose of this study was to experimentally investigate the flexural behavior of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio (PR). Four configurations of lattice structure beams with positive, negative, hybrid PR, and a novel hybrid PR with graded density were manufactured via the laser powder bed fusion (LPBF) AM process and tested under four-point bending. The manufacturability, microstructure, micro-hardness, and flexural properties of the lattices were evaluated. During the bending tests, different failure mechanisms were observed, which were highly dependent on the type of lattice geometry. The best response in terms of absorbed energy was obtained for the functionally graded hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the positive PR (PPR) structure. This highlights the great potential for FGHPR lattices to be used in protective devices, load-bearing medical implants, and energy-absorbing applications."}],"department":[{"_id":"9"},{"_id":"158"}],"user_id":"48411","_id":"41488","language":[{"iso":"eng"}],"keyword":["General Materials Science"],"article_number":"4072"},{"type":"journal_article","publication":"International Journal of Fatigue","status":"public","user_id":"48411","department":[{"_id":"9"},{"_id":"158"}],"_id":"41490","language":[{"iso":"eng"}],"article_number":"107235","keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering","Mechanics of Materials","General Materials Science","Modeling and Simulation"],"publication_status":"published","publication_identifier":{"issn":["0142-1123"]},"citation":{"bibtex":"@article{Hein_Lopes Dias_Kokalj_Stangier_Hoyer_Tillmann_Schaper_2022, title={On the influence of physical vapor deposited thin coatings on the low-cycle fatigue behavior of additively processed Ti-6Al-7Nb alloy}, volume={166}, DOI={10.1016/j.ijfatigue.2022.107235}, number={107235}, journal={International Journal of Fatigue}, publisher={Elsevier BV}, author={Hein, Maxwell and Lopes Dias, Nelson Filipe and Kokalj, David and Stangier, Dominic and Hoyer, Kay-Peter and Tillmann, Wolfgang and Schaper, Mirko}, year={2022} }","mla":"Hein, Maxwell, et al. “On the Influence of Physical Vapor Deposited Thin Coatings on the Low-Cycle Fatigue Behavior of Additively Processed Ti-6Al-7Nb Alloy.” International Journal of Fatigue, vol. 166, 107235, Elsevier BV, 2022, doi:10.1016/j.ijfatigue.2022.107235.","short":"M.

Consequently, the future over dimensioning can be reduced. Furthermore, the improved prediction quality of the joining process simulation leads to an improvement in the simulation of load-bearing capacity as well. In this way, the entire sampling process can be performed virtually without any experimental investigations. This will contribute to the advancement of lightweight construction in the automotive industry. In this work, the frictional behavior is studied in dependence on the local joining process parameters. As a reference for the numerical investigations, clinch joints by means of a die with fixed geometry are joined. Additionally, a hardness mapping is performed on the microsection of the clinch joints. It shows the local strain hardening, which correlates with the forming degree in the simulation. Based on the occurring contacts and the local joining process parameters in the joining process simulation, the test matrix for the experimental friction tests is defined. The friction tests are carried out on a compression-torsion-tribometer. This type of tribometer is able to apply high interface pressures above the initial yield stress due to the specimen encapsulation. Besides, the pure joining part contact, the contact between the joining part and joining tool can be tested as well. The experimental test setup offers the possibility to evaluate the influences of temperature, relative velocity, interface pressure, and frictional stroke independently. Based on the results of the experimental friction tests, a friction model is created. The resulting friction model is integrated into the numerical joining process simulation via a subroutine. To validate the quality of the new friction modeling, the results of simulations are compared with the experiments in terms of load-stroke diagrams, joint geometry, and hardness mappings on the microsection.

In order to predict relevant properties of clinched joints and to ensure the reliability of the process, it is numerically simulated during the product development process. The prediction accuracy of the simulated process depends on the implemented friction model. Therefore, a new method for determining friction coefficients in sheet metal materials was developed and tested. The aim of this study is the numerical investigation of this experimental method by means of FE simulation. The experimental setup is modelled in a 3D numerical simulation taking into account the process parameters varying in the experiment, such as geometric properties, contact pressure and contact velocity. Furthermore, the contact description of the model is calibrated via the experimentally determined friction coefficients according to clinch-relevant parameter space. It is shown that the assumptions made in the determination of the experimental data in preliminary work are valid. In addition, it is investigated to what extent the standard Coulomb friction model in the FEM can reproduce the results of the experimental method.

Especially with small batch size, the incremental flow forming processes can be advantageous. The production of parts with complex geometry and locally graded material properties currently depicts a great challenge in the flow forming process. At this point, the usage of closed-loop control for the shape and properties could be a feasible new solution. The overall aim in this project is to establish an intelligent closed-loop control system for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces in a flow forming process. To reach this goal, a novel sensor concept for online measurements of the wall thickness reduction and the martensite content during forming process is proposed. It includes the setup of a modified flow forming machine and the integration of the sensor system in the machine control. Additionally, a simulation model for the flow forming process is presented which describes the forming process with regard to the plastic workpiece deformation, the induced α’-martensite fraction, and the sensor behavior. This model was used for designing a closed-loop process control of the wall thickness reduction that was subsequently realized at the real plant including online measured feedback from the sensor system.","lang":"eng"}],"publication":"Key Engineering Materials","title":"Innovative Online Measurement and Modelling Approach for Property-Controlled Flow Forming Processes","date_created":"2022-11-04T08:27:33Z","publisher":"Trans Tech Publications, Ltd.","year":"2022","quality_controlled":"1"},{"keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"language":[{"iso":"eng"}],"abstract":[{"text":"The further development of in-mold-assembly (IMA) technologies for structural hybrid components is of great importance for increasing the economic efficiency and thus the application potential.

In this process, the core structure, which is provided with stiffening ribs and functional elements, is formed and joined to two metal belts in one single step. For experimental validation of the concept, the development of a prototypic molding tool and the manufacturing of hybrid beams including process parameters are described. Three-point bending tests and optical measurement technologies are used to characterize the failure behavior and mechanical properties of the produced hybrid beams. It was found that the innovative IMA process enables the manufacturing of hybrid components with high energy absorption and low weight in one step.

Proactive change management of requirement changes yields the potential to handle such changes efficiently. A systematic approach is required for proactive change management to assess and reduce the risk of a requirement change with appropriate effort in industrial application. Within the paper at hand, a novel method for Proactive Management of Requirement Changes (ProMaRC) is presented. It is developed in close collaboration with industry experts and evaluated based on workshops, pilot users’ feedback, three industrial case studies from the automotive industry and five development projects from research. To limit the application effort, an automated approach for dependency analysis based on the machine learning technique BERT and semi-automated assessment of change likelihood and impact using a modified PageRank algorithm is developed. Applying the method, the risks of requirement changes are assessed systematically and reduced by means of proactive change measures. Evaluation shows high performance of dependency analysis and confirms the applicability and usefulness of the method. This contribution opens up the research space of proactive risk management for requirement changes which is currently almost unexploited. It enables more efficient product development.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Fluid Flow and Transfer Processes","Computer Science Applications","Process Chemistry and Technology","General Engineering","Instrumentation","General Materials Science"],"issue":"4","quality_controlled":"1","year":"2022","date_created":"2022-03-08T12:37:42Z","publisher":"MDPI AG","title":"Proactive Management of Requirement Changes in the Development of Complex Technical Systems"},{"publication":"Advanced Materials","abstract":[{"text":"Inspired by plant grafting, grafted vortex beams can be formed through grafting two or more helical phase profiles of optical vortex beams. Recently, grafted perfect vortex beams (GPVBs) have attracted much attention due to their unique optical properties and potential applications. However, the current method to generate and manipulate GPVBs requires a complex and bulky optical system, hindering further investigation and limiting its practical applications. Here, a compact metasurface approach for generating and manipulating GPVBs in multiple channels is proposed and demonstrated, which eliminates the need for such a complex optical setup. A single metasurface is utilized to realize various superpositions of GPVBs with different combinations of topological charges in four channels, leading to asymmetric singularity distributions. The positions of singularities in the superimposed beam can be further modulated by introducing an initial phase difference in the metasurface design. The work demonstrates a compact metasurface platform that performs a sophisticated optical task that is very challenging with conventional optics, opening opportunities for the investigation and applications of GPVBs in a wide range of emerging application areas, such as singular optics and quantum science.","lang":"eng"}],"keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"30","year":"2022","publisher":"Wiley","date_created":"2022-06-20T11:05:50Z","title":"Multichannel Superposition of Grafted Perfect Vortex Beams","type":"journal_article","status":"public","_id":"32068","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"user_id":"30525","article_number":"2203044","article_type":"original","publication_identifier":{"issn":["0935-9648","1521-4095"]},"publication_status":"published","intvolume":" 34","citation":{"ama":"Ahmed H, Intaravanne Y, Ming Y, et al.

Identification of individual health risk is an important decision-making basis for managing the pandemic risk of infection with SARS-CoV-2 in sports and return to play (RTP).Methods: This study aims 1) to analyze the longitudinal rate of seroprevalence of SARS-CoV-2 in German athletes, 2) to assess health-related consequences in athletes infected with SARS-CoV-2, and 3) to reveal effects of the COVID-19 pandemic in general and of a cleared SARS-CoV-2 infection on exercise performance. CoSmo-S is a prospective observational multicenter study establishing two cohorts: 1) athletes diagnosed positive for COVID-19 (cohort 1) and 2) federal squad athletes who perform their annual sports medical preparticipation screening (cohort 2). Comprehensive diagnostics including physical examination, laboratory blood analyses and blood biobanking, resting and exercise electrocardiogram (ECG), echocardiography, spirometry and exercise testing added by questionnaires are conducted at baseline and follow-up.Results and Conclusion: We expect that the results obtained, will allow us to formulate recommendations regarding RTP on a more evidence-based level."}],"type":"journal_article","publication":"International Journal of Public Health","doi":"10.3389/ijph.2022.1604414","title":"COVID-19 in German Competitive Sports: Protocol for a Prospective Multicenter Cohort Study (CoSmo-S)","date_created":"2022-02-25T12:02:37Z","author":[{"first_name":"Andreas Michael","last_name":"Niess","full_name":"Niess, Andreas Michael"},{"first_name":"Manuel","full_name":"Widmann, Manuel","last_name":"Widmann"},{"last_name":"Gaidai","id":"51214","full_name":"Gaidai, Roman","first_name":"Roman"},{"orcid":"0000-0003-0536-1481","last_name":"Gölz","full_name":"Gölz, Christian Johannes","id":"33725","first_name":"Christian Johannes"},{"first_name":"Isabel","full_name":"Schubert, Isabel","last_name":"Schubert"},{"full_name":"Castillo, Katty","last_name":"Castillo","first_name":"Katty"},{"full_name":"Sachs, Jan Philipp","last_name":"Sachs","first_name":"Jan Philipp"},{"first_name":"Daniel","last_name":"Bizjak","full_name":"Bizjak, Daniel"},{"first_name":"Shirin","last_name":"Vollrath","full_name":"Vollrath, Shirin"},{"first_name":"Fritz","full_name":"Wimbauer, Fritz","last_name":"Wimbauer"},{"first_name":"Azin","full_name":"Vogel, Azin","last_name":"Vogel"},{"first_name":"Karsten","last_name":"Keller","full_name":"Keller, Karsten"},{"full_name":"Burgstahler, Christof","last_name":"Burgstahler","first_name":"Christof"},{"last_name":"Quermann","full_name":"Quermann, Anne","first_name":"Anne"},{"first_name":"Arno","full_name":"Kerling, Arno","last_name":"Kerling"},{"first_name":"Gerald","full_name":"Schneider, Gerald","last_name":"Schneider"},{"full_name":"Zacher, Jonas","last_name":"Zacher","first_name":"Jonas"},{"first_name":"Katharina","full_name":"Diebold, Katharina","last_name":"Diebold"},{"first_name":"Maximilian","last_name":"Grummt","full_name":"Grummt, Maximilian"},{"last_name":"Beckendorf","full_name":"Beckendorf, Claudia","first_name":"Claudia"},{"last_name":"Buitenhuis","full_name":"Buitenhuis, Johannes","first_name":"Johannes"},{"first_name":"Florian","full_name":"Egger, Florian","last_name":"Egger"},{"first_name":"Andreas","last_name":"Venhorst","full_name":"Venhorst, Andreas"},{"last_name":"Morath","full_name":"Morath, Oliver","first_name":"Oliver"},{"last_name":"Barsch","full_name":"Barsch, Friedrich","first_name":"Friedrich"},{"full_name":"Mellwig, Klaus-Peter","last_name":"Mellwig","first_name":"Klaus-Peter"},{"last_name":"Oesterschlink","full_name":"Oesterschlink, Julian","first_name":"Julian"},{"full_name":"Wüstenfeld, Jan","last_name":"Wüstenfeld","first_name":"Jan"},{"first_name":"Hans-Georg","full_name":"Predel, Hans-Georg","last_name":"Predel"},{"first_name":"Peter","full_name":"Deibert, Peter","last_name":"Deibert"},{"first_name":"Birgit","full_name":"Friedmann-Bette, Birgit","last_name":"Friedmann-Bette"},{"full_name":"Mayer, Frank","last_name":"Mayer","first_name":"Frank"},{"first_name":"Anja","full_name":"Hirschmüller, Anja","last_name":"Hirschmüller"},{"first_name":"Martin","last_name":"Halle","full_name":"Halle, Martin"},{"first_name":"Jürgen Michael","last_name":"Steinacker","full_name":"Steinacker, Jürgen Michael"},{"last_name":"Wolfarth","full_name":"Wolfarth, Bernd","first_name":"Bernd"},{"first_name":"Tim","full_name":"Meyer, Tim","last_name":"Meyer"},{"first_name":"Erwin","last_name":"Böttinger","full_name":"Böttinger, Erwin"},{"last_name":"Flechtner-Mors","full_name":"Flechtner-Mors, Marion","first_name":"Marion"},{"full_name":"Bloch, Wilhelm","last_name":"Bloch","first_name":"Wilhelm"},{"first_name":"Bernhard","full_name":"Haller, Bernhard","last_name":"Haller"},{"first_name":"Kai","last_name":"Roecker","full_name":"Roecker, Kai"},{"first_name":"Claus","last_name":"Reinsberger","id":"48978","full_name":"Reinsberger, Claus"}],"volume":67,"publisher":"Frontiers Media SA","date_updated":"2023-08-15T13:49:50Z","citation":{"apa":"Niess, A.

Based on automated text mining and unsupervised machine learning, we collect, analyze, and interpret the IS discipline’s comprehensive research on platforms—comprising 11,049 papers spanning 44 years of research activity. From a cluster analysis concerning platform concepts’ semantically most similar words, we identify six research streams on platforms, each with their own platform terms. Based on interpreting the identified concepts vis-à-vis the extant research and considering a temporal perspective on the concepts’ application, we present a lexicon of platform concepts, to guide further research on platforms in the IS discipline. Researchers and managers can build on our results to position their work appropriately, applying a specific theoretical perspective on platforms in isolation or combining multiple perspectives to study platform phenomena at a more abstract level.","lang":"eng"}],"publication":"Electronic Markets","type":"journal_article"},{"user_id":"83408","department":[{"_id":"157"},{"_id":"43"}],"project":[{"name":"TRR 285: TRR 285","_id":"130","grant_number":"418701707"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C04: TRR 285 - Subproject C04","_id":"148"}],"_id":"51197","language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"type":"journal_article","publication":"Key Engineering Materials","status":"public","abstract":[{"text":"Clinching is a cost efficient method for joining components in series production. To assure the clinch point’s quality, the force displacement curve during clinching or the bottom thickness are monitored. The most significant geometrical characteristics of the clinch point, neck thickness and undercut, are usually tested destructively by microsectioning. However, micrograph preparation goes ahead with a resetting of elastic deformations and crack-closing after unloading. To generate a comprehensive knowledge of the clinch point’s inner geometry under load, in-situ computed tomography (CT) and acoustic testing (TDA) can be combined. While the TDA is highly sensitive to the inner state of the clinch point, it could detect critical events like crack development during loading. If such events are indicated, the loading process is stopped and a stepped in-situ CT of the following crack and deformation development is performed. In this paper, the concept is applied to the process of clinching itself, providing a detailed three-dimensional insight in the development of the joining zone. A test set-up is used which allows a stepwise clinching of two aluminium sheets EN AW 6014. Furthermore, this set-up is positioned within a CT system. In order to minimize X-ray absorption, a beryllium cylinder is used within the set-up frame and clinching tools are made from Si3N4. The actuator and sensor necessary for the TDA are integrated in the set-up. In regular process steps, the clinching process is interrupted in order to perform a TDA and a CT scan. In order to enhance the visibility of the interface, a thin tin layer is positioned between the sheets prior clinching. It is shown, that the test-set up allows a monitoring of the dynamic behaviour of the specimen during clinching while the CT scans visualize the inner geometry and material flow non-destructively.","lang":"eng"}],"date_created":"2024-02-06T15:04:45Z","author":[{"first_name":"Daniel","full_name":"Köhler, Daniel","last_name":"Köhler"},{"last_name":"Stephan","full_name":"Stephan, Richard","first_name":"Richard"},{"first_name":"Robert","last_name":"Kupfer","full_name":"Kupfer, Robert"},{"first_name":"Juliane","last_name":"Troschitz","full_name":"Troschitz, Juliane"},{"first_name":"Alexander","last_name":"Brosius","full_name":"Brosius, Alexander"},{"first_name":"Maik","full_name":"Gude, Maik","last_name":"Gude"}],"volume":926,"publisher":"Trans Tech Publications, Ltd.","date_updated":"2025-06-02T20:21:13Z","doi":"10.4028/p-32330d","title":"Investigations on Combined <i>In Situ</i> CT and Acoustic Analysis during Clinching","publication_status":"published","publication_identifier":{"issn":["1662-9795"]},"citation":{"apa":"Köhler, D., Stephan, R., Kupfer, R., Troschitz, J., Brosius, A., & Gude, M.
