As the mobility sector is a major contributor to CO2, various strategies are being pursued to achieve the climate targets set. An increasingly applied lightweight design method is the use of multi-material constructions. To join these structures, mechanical joining technologies such as self-pierce riveting are being used. As a result of the currently rigid tool systems, which cannot react to changing boundary conditions, a large number of rivet–die combinations is required to join the rising number of materials as well as material thickness combinations. Thus, new, versatile joining technologies are needed that can react to the described changes. The versatile self-piercing riveting (V-SPR) process is one possible approach. In this process, different material thicknesses can be joined by using a multi-range capable rivet which is set by a joining system with extended actuator technology. In this study, the V-SPR joining process is analysed numerically according to the influence of the geometrical rivet parameters on the joints characteristics as well as the resulting material flow. The investigations showed that the shank geometry has a decisive influence on the expansion of the rivet. Furthermore, the rivet length could be proven to be an influencing factor. By changing the head radii and the protrusion height, the forming behaviour of the rivet head onto the punch-sided joining part could be improved and thus the formation of air pockets was prevented. Based on the numerical investigations, a novel rivet geometry was developed and produced by machining. Subsequently, experimentally produced joints were analysed according to their joint formation and load-bearing capacity.","lang":"eng"}],"date_created":"2025-09-23T13:06:35Z","department":[{"_id":"43"},{"_id":"157"}],"type":"journal_article"},{"citation":{"ieee":"S.

Its introduction is forcing companies to undertake major transformation initiatives. As established change management approaches show, the corporate culture is an important key criterion for success of transformation. Therefore, when introducing Systems Engineering into an organization, transformation initiatives must be tailored to an existing corporate culture or the corporate culture itself must be changed in order to enable Systems Engineering. In literature and in industrial practice, different approaches for assessment of corporate culture exist. Within this research, a systematic literature review on methods and models for corporate culture assessment is conducted. Core elements are collected and combined with the fundamentals and success factors of Systems Engineering to develop a model for corporate culture assessment. The developed model is applied to the industrial practice of an ongoing Systems Engineering transformation of a large car manufacturer. The results of the assessment are compared with the emerging project challenges. Based on this model and its supporting tool and templates, organizations and transformation leaders are enabled to rapidly obtain an orientation of hindering or supporting currently established cultural aspects with regard to Systems Engineering transformation and to provide a decision basis for further measures.","lang":"eng"}],"publication":"AHFE International","department":[{"_id":"152"}],"type":"conference","date_created":"2024-10-17T15:13:46Z","intvolume":" 158","publication_status":"published","date_updated":"2025-11-11T06:11:50Z","publication_identifier":{"issn":["2771-0718"]},"author":[{"full_name":"Graessler, Iris","last_name":"Graessler","first_name":"Iris"},{"full_name":"Grewe, Benedikt","last_name":"Grewe","first_name":"Benedikt"}],"year":"2024","title":"Importance of cultural change in Systems Engineering Transformation: A model for cultural assessment","doi":"10.54941/ahfe1005551","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://openaccess.cms-conferences.org/publications/book/978-1-964867-34-2/article/978-1-964867-34-2_28"}]},{"publication":"AHFE International","type":"conference","department":[{"_id":"43"},{"_id":"9"},{"_id":"26"},{"_id":"152"}],"date_created":"2024-10-07T07:33:08Z","publication_status":"published","date_updated":"2025-11-13T16:42:28Z","intvolume":" 158","year":"2024","title":"Quality Key Figures for Developing Future Scenarios","publication_identifier":{"unknown":["2771-0718"]},"author":[{"id":"47565","last_name":"Gräßler","first_name":"Iris","orcid":"0000-0001-5765-971X","full_name":"Gräßler, Iris"},{"full_name":"Özcan, Deniz","first_name":"Deniz","last_name":"Özcan","id":"58595"}],"doi":"10.54941/ahfe1005553","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"chicago":"Gräßler, Iris, and Deniz Özcan. “Quality Key Figures for Developing Future Scenarios.” In AHFE International, Vol. 158.

This method’s integration of parametric space information significantly reduces the amount of training data needed to effectively predict high-fidelity solutions from low-fidelity ones. In this study, we examine a two-dimensional steady-state heat transfer analysis within a heterogeneous materials microstructure. The heat conductivity coefficients for two different materials are condensed from a 101 \r\n \r\n $$\\times $$\r\n \r\n ×\r\n \r\n \r\n 101 grid to smaller grids. We then solve the boundary value problem on the coarsest grid using a pre-trained physics-informed neural operator network known as Finite Operator Learning (FOL). The resulting low-fidelity solution is subsequently upscaled back to a 101 \r\n \r\n $$\\times $$\r\n \r\n ×\r\n \r\n \r\n 101 grid using a newly designed enhanced autoencoder. The novelty of the developed enhanced autoencoder lies in the concatenation of heat conductivity maps of different resolutions to the decoder segment in distinct steps. Hence the developed algorithm is named microstructure-embedded autoencoder (MEA). We compare the MEA outcomes with those from finite element methods, the standard U-Net, and an interpolation approach as an upscaling technique. Our analysis shows that MEA outperforms these methods in terms of computational efficiency and error on representative test cases. As a result, the MEA serves as a potential supplement to neural operator networks, effectively upscaling low-fidelity solutions to high-fidelity while preserving critical details often lost in traditional upscaling methods, such as sharp interfaces features lost in the context of interpolation approaches."}],"issue":"4","publication":"Computational Mechanics","department":[{"_id":"952"},{"_id":"321"}],"type":"journal_article","date_created":"2025-12-03T12:37:08Z"},{"user_id":"85414","volume":94,"page":"2217-2242","_id":"62770","publisher":"Springer Science and Business Media LLC","status":"public","quality_controlled":"1","citation":{"apa":"Gerlach, J., Schulte, R., Schowtjak, A., Clausmeyer, T., Ostwald, R., Tekkaya, A.

As representative example case-hardened steel 16MnCrS5 is elaborated. An artificial neural network (ANN) is initially trained by using load–displacement curves derived from simulations of a boundary value problem—instead of using data generated for homogeneous states of deformation at material point or one-element level—with varying material parameter combinations. The ANN is then employed so as to predict sets of material parameters that already provide close solutions to the experiment. These predicted parameter sets serve as starting values for a subsequent multi-objective parameter identification by using ADAPT. ADAPT allows for the consideration of input data from multiple scales, including integral data such as load–displacement curves, full-field data such as displacement and strain fields, and high-resolution experimental void data at the micro-scale. The influence of each data set on prediction quality is analyzed. Using various types of input data introduces additional information, enhancing prediction accuracy. The validation is carried out with respect to experimental void measurements of forward rod extruded parts. The results demonstrate, by incorporating void measurements in the optimization process, that it is possible to improve the quantitative prediction of ductile damage in the sense of void area fractions by factor 28 in forward rod extrusion.","lang":"eng"}],"issue":"8","publication":"Archive of Applied Mechanics"},{"publication":"Engineering Fracture Mechanics","date_created":"2025-12-03T12:40:42Z","type":"journal_article","department":[{"_id":"952"},{"_id":"321"}],"title":"A spatiotemporal deep learning framework for prediction of crack dynamics in heterogeneous solids: Efficient mapping of concrete microstructures to its fracture properties","year":"2024","author":[{"full_name":"Najafi Koopas, Rasoul","last_name":"Najafi Koopas","first_name":"Rasoul"},{"first_name":"Shahed","last_name":"Rezaei","full_name":"Rezaei, Shahed"},{"full_name":"Rauter, Natalie","last_name":"Rauter","first_name":"Natalie"},{"id":"106876","full_name":"Ostwald, Richard","orcid":"0000-0003-2147-8444","last_name":"Ostwald","first_name":"Richard"},{"first_name":"Rolf","last_name":"Lammering","full_name":"Lammering, Rolf"}],"publication_identifier":{"issn":["0013-7944"]},"publication_status":"published","date_updated":"2025-12-03T12:51:12Z","intvolume":" 314","article_number":"110675","language":[{"iso":"eng"}],"doi":"10.1016/j.engfracmech.2024.110675","citation":{"mla":"Najafi Koopas, Rasoul, et al. “A Spatiotemporal Deep Learning Framework for Prediction of Crack Dynamics in Heterogeneous Solids: Efficient Mapping of Concrete Microstructures to Its Fracture Properties.” Engineering Fracture Mechanics, vol. 314, 110675, Elsevier BV, 2024, doi:10.1016/j.engfracmech.2024.110675.","ama":"Najafi Koopas R, Rezaei S, Rauter N, Ostwald R, Lammering R.

We provide empirical evidence that the mixed results are due to the difficulty of identifying reliable variables to measure concentration and market power.Design/methodology/approachUsing data from 3,943 banks operating in the European Union (EU)-15 between 2013 and 2020, we employ linear regression models on panel data. Banking market concentration is measured by the Herfindahl–Hirschman Index (HHI), and market power is estimated by the product-specific Lerner Indices for the loan and deposit market, respectively.FindingsOur analysis reveals a significantly stability-decreasing impact of market concentration (HHI) and a significantly stability-increasing effect of market power (Lerner Indices). In addition, we provide evidence for a weak (or even absent) empirical relationship between the (non)structural measures, challenging the validity of the structure-conduct-performance (SCP) paradigm. Our baseline findings remain robust, especially when controlling for a likely reverse causality.Originality/valueOur results suggest that the HHI may reflect other factors beyond market power that influence banking stability. Thus, banking supervisors and competition authorities should investigate market concentration and market power simultaneously while considering their joint impact on banking stability."}],"publication":"The Journal of Risk Finance","issue":"3","user_id":"50109","volume":25,"page":"510-536","publisher":"Emerald","_id":"62999","status":"public","citation":{"bibtex":"@article{Herwald_Voigt_Uhde_2024, title={The impact of market concentration and market power on banking stability – evidence from Europe}, volume={25}, DOI={10.1108/jrf-03-2023-0075}, number={3}, journal={The Journal of Risk Finance}, publisher={Emerald}, author={Herwald, Sarah and Voigt, Simone and Uhde, André}, year={2024}, pages={510–536} }","ama":"Herwald S, Voigt S, Uhde A.

In this investigation, the focus is on describing and characterising the failure behaviour of connections manufactured by an innovative thermomechanical joining process with adaptable auxiliary joining elements in single-lap tensile-shear tests. In order to analyse the failure development in detail, the specimens are investigated using in-situ computed tomography (in-situ CT). Here, the tensile-shear test is interrupted at points of interest and CT scans are conducted under load. In addition, the interrupted in-situ testing procedure is validated by comparing the loading behaviour with conventional continuous tensile-shear tests. The results of the in-situ investigations of joints with varying material combinations clearly describe the cause of failure, allowing conclusions towards an improved joint design.

This model can be prospectively used inside a closed-loop property-controlled flow forming process. To achieve this, optimization by means of a non-linear regression of experimental data was carried out. To collect the experimental data, specimens were produced by flow forming seamless tubes at room temperature. Using a combination of production parameters (like the infeed depth and feed rate), specimens with different α’-martensite contents and wall-thickness reductions were produced. An equation to compute α’-martensite from both specific production-process parameters and micromagnetic Barkhausen noise (MBN) measurements was obtained using numerical methods. In this process, the behavior of the quantity of interest (namely, the α’-martensite content) was mathematically evaluated with respect to non-destructive MBN data and the feed rate that was used to produce the components. A combination of exponential and potential functions was defined as the ansatz functions of the model. The obtained model was validated online and offline during the real flow forming of workpieces, obtaining average deviations of up to 7% α’-martensite with respect to the model. The implementation of the soft sensor model for property-controlled production represents an important milestone for producing high-added-value components on the basis of a well-understood process-microstructure-property relationship.","lang":"eng"}],"quality_controlled":"1","publication":"Lecture Notes in Mechanical Engineering","citation":{"apa":"Rozo Vasquez, J., Kersting, L., Arian, B., Homberg, W., Trächtler, A., & Walther, F.
