The scale spanning heterogeneity of their material structure and its influence on the material behavior, however, presents significant challenges for most joining technologies, such as self-piercing riveting (SPR). During mechanical joining, the material structure is significantly altered within and around the joining zone, heavily influencing the material behavior. A comprehensive understanding of the underlying phenomena of material alteration during the SPR process is essential as basis for validating numerical simulations. This study examines the material structure at ten stages of a step-setting test of SPR with two FRTP sheets with glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage phenomena within different areas of the setting test are analyzed three-dimensionally and key parameters are quantified. Dominating phenomena during the penetration of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF) and fiber bending, while delamination, fiber kinking and roving splitting are also observed. At the final stages, the bottom layers of the second sheet collapse and form a bulge into the cavity of the die.","lang":"eng"}],"publication":"Proceedings of the 8th International Conference on Integrity-Reliability-Failure (IRF2025)","keyword":["self-piercing riveting","computed tomography","thermoplastic composites","process-structure-interaction"],"type":"conference","date_created":"2025-09-08T11:52:45Z","conference":{"location":"Porto","name":"8th International Conference on Integrity-Reliability-Failure (IRF2025)","start_date":"2025-07-15","end_date":"2025-07-18"},"status":"public","editor":[{"full_name":"Gomes, J.F.

In particular, the car body offers several opportunities for weight reduction. Multi-material designs are increasingly being applied to select the most suitable material for the respective load and ultimately achieve synergy effects. For example, aluminium castings are used at the nodes of a spaceframe body. Subsequently, these are joined with profiles to form the bodyshell. To join different materials mechanical joining techniques, such as semi-tubular self-piercing riveting, are deployed. According to the current state of the art, cracks occur in the aluminium castings during the mechanical joining process as a result of the high degree of deformation. Although the aluminium casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent castability. In particular, the ability to cast thin structural parts is enabled by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis study addresses the mechanical joining properties of the near eutectic aluminium casting alloy AlSi12, depending on different microstructures. These are achieved by annealing processes and modifying agents. Through an adapted heat treatment, the previously lamellar morphology can be transformed into a globular morphology, which leads to increased ductility and prevents the formation of cracks during the self-piercing riveting (SPR). The joinability is investigated using different die geometries, whereas the joint formation is analysed regarding crack initiation. To evaluate the increased ductility, microstructural and mechanical tests are performed and finally, a microstructure-joinability correlation is established.","lang":"eng"}],"publication":"The Journal of Materials: Design and Applications, Part L","keyword":["aluminium","casting","microstructure","joinability","self-piercing riveting"],"type":"journal_article","department":[{"_id":"43"},{"_id":"158"},{"_id":"157"},{"_id":"9"},{"_id":"321"}],"date_created":"2025-02-24T10:25:31Z","has_accepted_license":"1","status":"public","conference":{"end_date":"2024-07-05","name":"5th International Conference on Materials Design and Applications 2024","start_date":"2024-07-04","location":"Porto, Portugal"},"user_id":"7850","_id":"58807","publisher":"Sage Publications","quality_controlled":"1","project":[{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"name":"TRR 285 – A02: TRR 285 - Subproject A02","_id":"136"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"_id":"146","name":"TRR 285 – C02: TRR 285 - Subproject C02"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"citation":{"mla":"Neuser, Moritz, et al. “Mechanical Properties and Joinability of the Near-Eutectic Aluminium Casting Alloy AlSi12.” <i>The Journal of Materials: Design and Applications, Part L</i>, Sage Publications, 2025, doi:<a href=\"https://doi.org/10.1177/14644207251319922\">10.1177/14644207251319922</a>.","ama":"Neuser M, Holtkamp PK, Hoyer K-P, et al.

Existing approaches often utilize impedance measurements over a range of frequencies or velocity measurements and require additional equipment or sensors, such as a laser Doppler vibrometer. Furthermore, the non-negligible effects of varying operating conditions are often unconsidered. To minimize the need for additional sensors while maintaining the dependability of piezoelectric bending actuators irrespective of varying operating conditions, an online diagnostics approach is proposed. To this end, time- and frequency-domain features are extracted from monitored current signals to reflect hairline crack development in bending actuators. For validation of applicability, the presented analysis method was evaluated on piezoelectric bending actuators subjected to accelerated lifetime tests at varying voltage amplitudes and under external damping conditions. In the presence of a crack and due to a diminished stiffness, the resonance frequency decreases and the root-mean-square amplitude of the current signal simultaneously abruptly drops during the lifetime tests. Furthermore, the piezoelectric crack surfaces clapping is reflected in higher harmonics of the current signal. Thus, time-domain features and harmonics of the current signals are sufficient to diagnose hairline cracks in the actuators.","lang":"eng"}],"date_created":"2024-02-20T06:46:43Z","department":[{"_id":"151"}],"keyword":["piezoelectric transducer","self-sensing","fault detection","diagnostics","hairline crack","condition monitoring"],"type":"journal_article","status":"public","_id":"51518","publisher":"MDPI AG","funded_apc":"1","volume":13,"user_id":"9557","citation":{"mla":"Aimiyekagbon, Osarenren Kennedy, et al. “Diagnostics of Piezoelectric Bending Actuators Subjected to Varying Operating Conditions.” <i>Electronics</i>, vol. 13, no. 3, 521, MDPI AG, 2024, doi:<a href=\"https://doi.org/10.3390/electronics13030521\">10.3390/electronics13030521</a>.","bibtex":"@article{Aimiyekagbon_Bender_Hemsel_Sextro_2024, title={Diagnostics of Piezoelectric Bending Actuators Subjected to Varying Operating Conditions}, volume={13}, DOI={<a href=\"https://doi.org/10.3390/electronics13030521\">10.3390/electronics13030521</a>}, number={3521}, journal={Electronics}, publisher={MDPI AG}, author={Aimiyekagbon, Osarenren Kennedy and Bender, Amelie and Hemsel, Tobias and Sextro, Walter}, year={2024} }","ama":"Aimiyekagbon OK, Bender A, Hemsel T, Sextro W.

This points to a substantial opportunity for further optimization in material savings and process design. The current study delves into the advancement of sustainable manufacturing practices in the automotive industry, emphasizing the crucial role of lightweight construction concepts and AM technologies in enhancing resource efficiency and reducing greenhouse gas emissions. By exploring the integration of novel AM techniques such as selective laser melting (SLM) and laser metal deposition (LMD), the study aims to overcome existing limitations like slow build-up rates and limited component resolution. The study’s core objective revolves around the development and validation of a continuous process chain that synergizes different AM routes. In the current study, the continuous process chain for DMG MORI Lasertec 65 3D’s LMD system and the DMG MORI Lasertec 30 3D’s was demonstrated using 316L and 1.2709 steel materials. This integrated approach is designed to significantly curtail process times and minimize component costs, thus suggesting an industry-oriented process chain for future manufacturing paradigms. Additionally, the research investigates the production and material behavior of components under varying manufacturing processes, material combinations, and boundary layer materials. The culmination of this study is the validation of the proposed process route through a technology demonstrator, assessing its scalability and setting a benchmark for resource-efficient manufacturing in the automotive sector.</jats:p>"}],"publication":"Metals","issue":"7","keyword":["additive manufacturing (AM)","selective laser melting (SLM)","laser metal deposition (LMD)","hybrid manufacturing","process optimization","316L","1.2709"],"type":"journal_article","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"date_created":"2024-09-10T10:19:32Z"},{"doi":"10.1080/08856257.2023.2195075","main_file_link":[{"open_access":"1","url":"https://www.tandfonline.com/doi/epdf/10.1080/08856257.2023.2195075?needAccess=true"}],"language":[{"iso":"eng"}],"date_updated":"2026-08-22T12:21:28Z","publication_status":"published","intvolume":"        39","article_type":"original","year":"2024","title":"Measuring collective efficacy for inclusion in a global context","author":[{"last_name":"Sharma ","first_name":" Umesh ","full_name":"Sharma ,  Umesh "},{"first_name":" Tim ","last_name":"Loreman ","full_name":"Loreman ,  Tim "},{"full_name":"May ,  Fiona ","last_name":"May ","first_name":" Fiona "},{"full_name":"Romano ,  Alessandra ","last_name":"Romano ","first_name":" Alessandra "},{"last_name":"Lozano ","first_name":"Caroline Sahli","full_name":"Lozano , Caroline Sahli"},{"full_name":"Avramidis ,  Elias ","first_name":" Elias ","last_name":"Avramidis "},{"first_name":" Stuart ","last_name":"Woodcock ","full_name":"Woodcock ,  Stuart "},{"last_name":"Subban ","first_name":" Pearl ","full_name":"Subban ,  Pearl "},{"full_name":"Kullmann, Harry","last_name":"Kullmann","first_name":"Harry","orcid":"0000-0001-5488-5105","id":"77972"}],"type":"journal_article","keyword":["Inclusive education","teacher attitudes","teacher self- efficacy","collective efficacy"],"department":[{"_id":"556"}],"date_created":"2023-03-28T13:01:09Z","abstract":[{"text":"Previous research has identified the importance of teacher attitudes and self-efficacy in supporting inclusive education.

However, these benchmark functions have faced criticism for their limited resemblance to real-world problems. In response, recent research has focused on automatically generating new benchmark functions for areas where established test suites are inadequate. These approaches have limitations, such as the difficulty of generating new benchmark functions that exhibit exploratory landscape analysis (ELA) features beyond those of existing benchmarks.The objective of this work is to develop a method for generating benchmark functions for single-objective continuous optimization with user-specified structural properties. Specifically, we aim to demonstrate a proof of concept for a method that uses an ELA feature vector to specify these properties in advance. To achieve this, we begin by generating a random sample of decision space variables and objective values. We then adjust the objective values using CMA-ES until the corresponding features of our new problem match the predefined ELA features within a specified threshold. By iteratively transforming the landscape in this way, we ensure that the resulting function exhibits the desired properties. To create the final function, we use the resulting point cloud as training data for a simple neural network that produces a function exhibiting the target ELA features. We demonstrate the effectiveness of this approach by replicating the existing functions of the well-known BBOB suite and creating new functions with ELA feature values that are not present in BBOB.","lang":"eng"}],"publication":"Proceedings of the 17th ACM/SIGEVO Conference on Foundations of Genetic Algorithms","doi":"10.1145/3594805.3607136","language":[{"iso":"eng"}],"series_title":"FOGA ’23","date_updated":"2023-10-16T12:33:02Z","title":"Neural Networks as Black-Box Benchmark Functions Optimized for Exploratory Landscape Features","year":"2023","author":[{"full_name":"Prager, Raphael Patrick","first_name":"Raphael Patrick","last_name":"Prager"},{"full_name":"Dietrich, Konstantin","first_name":"Konstantin","last_name":"Dietrich"},{"first_name":"Lennart","last_name":"Schneider","full_name":"Schneider, Lennart"},{"first_name":"Lennart","last_name":"Schäpermeier","full_name":"Schäpermeier, Lennart"},{"last_name":"Bischl","first_name":"Bernd","full_name":"Bischl, Bernd"},{"full_name":"Kerschke, Pascal","first_name":"Pascal","last_name":"Kerschke"},{"full_name":"Trautmann, Heike","first_name":"Heike","orcid":"0000-0002-9788-8282","last_name":"Trautmann","id":"100740"},{"last_name":"Mersmann","first_name":"Olaf","full_name":"Mersmann, Olaf"}],"publication_identifier":{"isbn":["9798400702020"]}},{"language":[{"iso":"eng"}],"series_title":"GECCO’23","doi":"10.1145/3583131.3590384","publication_identifier":{"isbn":["9798400701191"]},"author":[{"orcid":"0000-0002-4121-4668","first_name":"Jakob","last_name":"Bossek","full_name":"Bossek, Jakob","id":"102979"},{"first_name":"Aneta","last_name":"Neumann","full_name":"Neumann, Aneta"},{"last_name":"Neumann","first_name":"Frank","full_name":"Neumann, Frank"}],"year":"2023","title":"On the Impact of Basic Mutation Operators and Populations within Evolutionary Algorithms for the Dynamic Weighted Traveling Salesperson Problem","date_updated":"2023-12-13T10:46:27Z","date_created":"2023-11-14T15:58:56Z","department":[{"_id":"819"}],"type":"conference","keyword":["dynamic optimization","evolutionary algorithms","re-optimization","weighted traveling salesperson problem"],"publication":"Proceedings of the Genetic and Evolutionary Computation Conference","extern":"1","abstract":[{"text":"Evolutionary algorithms have been shown to obtain good solutions for complex optimization problems in static and dynamic environments. It is important to understand the behaviour of evolutionary algorithms for complex optimization problems that also involve dynamic and/or stochastic components in a systematic way in order to further increase their applicability to real-world problems. We investigate the node weighted traveling salesperson problem (W-TSP), which provides an abstraction of a wide range of weighted TSP problems, in dynamic settings. In the dynamic setting of the problem, items that have to be collected as part of a TSP tour change over time. We first present a dynamic setup for the dynamic W-TSP parameterized by different types of changes that are applied to the set of items to be collected when traversing the tour. Our first experimental investigations study the impact of such changes on resulting optimized tours in order to provide structural insights of optimization solutions.

Agency is understood as a multifaceted construct describing the idea that human beings make choices, act on these choices, and thereby exercise influence on their own lives as well as their environment. We argue that the concept is discussed from three different perspectives in the literature—transformational, dispositional, and relational—that are each related to learning and development in work contexts. These perspectives do not reflect incompatible positions but rather different aspects of the same phenomena. The chapter also offers an avenue of insight into empirical studies that employ agency as a central concept as well as discussions about concepts that closely overlap with ideas of human beings as agents of power and influence.","lang":"eng"}],"related_material":{"link":[{"url":"https://link.springer.com/chapter/10.1007/978-3-030-89582-2_1#Abs1","relation":"other"}]},"date_created":"2022-03-13T19:09:20Z","department":[{"_id":"452"}],"keyword":["Agency Workplace learning Professional development Proactivity Self-direction"],"type":"book_chapter"},{"publication":"Research Approaches on Workplace Learning","abstract":[{"text":"The article explores the particular quality of changes introduced through the latest wave of digital transformation of workplaces.

This discovery can be achieved with continuous experimentation, testing different software variants with distinct user groups, and deploying the superior variant for all users. However, existing approaches do not focus on explicit modeling of variants and experiments, which offers advantages such as traceability of decisions and combinability of experiments. Therefore, our vision is the provision of model-driven continuous experimentation, which provides the developer with a framework for structuring the experimentation process. For that, we introduce the overall concept, apply it to the experimentation on component-based software architectures and point out future research questions. In particular, we show the applicability by combining feature models for modeling the software variants, users, and experiments (i.e., model-driven) with MAPE-K for the adaptation (i.e., continuous experimentation) and implementing the concept based on the component-based Angular framework."}],"publication":"Proceedings of the 18th International Conference on Software Architecture Companion ","user_id":"47208","ddc":["000"],"publisher":"IEEE","_id":"29842","has_accepted_license":"1","status":"public","conference":{"start_date":"2022-03-12","name":"18th International Conference on Software Architecture ","location":"Hawaii","end_date":"2022-03-15"},"oa":"1","project":[{"name":"SFB 901: SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - C: SFB 901 - Project Area C"},{"_id":"17","name":"SFB 901 - C5: SFB 901 - Subproject C5"}],"file_date_updated":"2022-07-04T12:34:52Z","citation":{"mla":"Gottschalk, Sebastian, et al. “Model-Driven Continuous Experimentation on Component-Based Software Architectures .” <i>Proceedings of the 18th International Conference on Software Architecture Companion </i>, IEEE, 2022, doi:<a href=\"https://doi.org/10.1109/ICSA-C54293.2022.00011\">10.1109/ICSA-C54293.2022.00011</a>.","bibtex":"@inproceedings{Gottschalk_Yigitbas_Engels_2022, title={Model-driven Continuous Experimentation on Component-based Software Architectures }, DOI={<a href=\"https://doi.org/10.1109/ICSA-C54293.2022.00011\">10.1109/ICSA-C54293.2022.00011</a>}, booktitle={Proceedings of the 18th International Conference on Software Architecture Companion }, publisher={IEEE}, author={Gottschalk, Sebastian and Yigitbas, Enes and Engels, Gregor}, year={2022} }","ama":"Gottschalk S, Yigitbas E, Engels G.
