This is crucial for capturing the local material structure after processes introducing highly localized deformation such as mechanical joining processes between metal and fiber reinforced thermoplastics (FRTP). A generic finite element (FE) model is developed, incorporating interfaces discretized through either cohesive zone (CZ) elements or Coulomb friction-based contacts. The material parameters for the FE elements are derived from the initial stiffness of a statistical volume element (SVE) at micro scale modelled with an Arbitrary-Lagrange-Eulerian method for three load cases. The CZ properties calculated are based on the shear viscosity of the composite. The CZ and contact modelling approaches are evaluated using three load cases of the SVE, comparing force-displacement curves. Under simple loading conditions, such as normal pressure tension and bending, both methods produce similar results; however, in complex load cases, the CZ approach shows clear advantages in handling interface interactions and shows robust simulations. The CZ approach thus presents a promising method for simulating roving decomposition in FRTP-metal joining applications above the matrix{\\textquoteright} melting temperature."}],"language":[{"iso":"eng"}],"keyword":["Finite Element Method (FEM)","Process","Thermoplastic Fiber Reinforced Plastic"],"publication_identifier":{"isbn":["978-1-64490-354-4"]},"citation":{"chicago":"Gröger, Benjamin, Johannes Gerritzen, Andreas Hornig, and Maik Gude. “Modeling Approaches for the Decomposition Behavior of Preconsolidated Rovings throughout Local Deformation Processes.” In Sheet Metal 2025, edited by G.

However, this information cannot be directly used for structural analyses, since it requires a discretization on micrometer level. Therefore, current failure theories do not directly account for such effects, but describe the behavior averaged over an entire specimen. This foundation in experimentally accessible loading conditions leads to purely theory based extension to more complex stress states without direct validation possibilities. This work aims at leveraging micro-scale simulations to obtain failure information under arbitrary loading conditions. The results are propagated to the meso-scale, enabling efficient structural analyses, by means of machine learning (ML). It is shown that the ML model is capable of correctly assessing previously unseen stress states and therefore poses an efficient tool of exploiting information from the micro-scale in larger simulations."}],"editor":[{"first_name":"G.","last_name":"Meschut","full_name":"Meschut, G."},{"last_name":"Bobbert","full_name":"Bobbert, M.","first_name":"M."},{"full_name":"Duflou, J.","last_name":"Duflou","first_name":"J."},{"first_name":"L.","full_name":"Fratini, L.","last_name":"Fratini"},{"first_name":"H.","full_name":"Hagenah, H.","last_name":"Hagenah"},{"first_name":"P.","last_name":"Martins","full_name":"Martins, P."},{"full_name":"Merklein, M.","last_name":"Merklein","first_name":"M."},{"first_name":"F.","full_name":"Micari, F.","last_name":"Micari"}],"status":"public","publisher":"Materials Research Forum LLC, Materials Research Foundations","date_updated":"2026-02-27T06:43:37Z","author":[{"first_name":"Johannes","full_name":"Gerritzen, Johannes","id":"105344","last_name":"Gerritzen","orcid":"0000-0002-0169-8602"},{"first_name":"Andreas","full_name":"Hornig, Andreas","last_name":"Hornig"},{"first_name":"Maik","full_name":"Gude, Maik","last_name":"Gude"}],"date_created":"2025-11-04T12:48:37Z","title":"Efficient failure information propagation under complex stress states in fiber reinforced polymers: From micro- to meso-scale using machine learning","doi":"10.21741/9781644903551-32","publication_identifier":{"isbn":["978-1-64490-354-4"]},"year":"2025","citation":{"bibtex":"@inproceedings{Gerritzen_Hornig_Gude_2025, series={Materials Research Proceedings}, title={Efficient failure information propagation under complex stress states in fiber reinforced polymers: From micro- to meso-scale using machine learning}, DOI={10.21741/9781644903551-32}, booktitle={Sheet Metal 2025}, publisher={Materials Research Forum LLC, Materials Research Foundations}, author={Gerritzen, Johannes and Hornig, Andreas and Gude, Maik}, editor={Meschut, G. and Bobbert, M. and Duflou, J. and Fratini, L. and Hagenah, H. and Martins, P. and Merklein, M. and Micari, F.}, year={2025}, pages={260–267}, collection={Materials Research Proceedings} }","short":"J.

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"}],"language":[{"iso":"eng"}],"keyword":["self-piercing riveting","computed tomography","thermoplastic composites","process-structure-interaction"],"year":"2025","date_created":"2025-09-08T11:52:45Z","publisher":"FEUP","title":"LOCAL DEFORMATION AND FAILURE OF COMPOSITES DURING SELF-PIERCING RIVETING: A CT BASED MICROSTRUCTURE INVESTIGATION","type":"conference","status":"public","editor":[{"first_name":"J.F.

Accurate Finite Element Modeling (FEM) of joints is essential in the design of complex mechanical systems such as automotive body-in-white (BIW) structures, as it plays a critical role in evaluating their performance. Although well-established techniques exist for modeling rotationally symmetric joints, there remains a significant gap in effectively modeling non-rotationally symmetric joints. These joints are particularly relevant in the automotive BIW, where they can better accommodate anisotropic loading conditions. In this study, strategies for modeling non-rotationally symmetric joints were explored using finite element simulations in LS-DYNA. The findings demonstrate that discrete beam elements can capture the anisotropic characteristics of such joints. Two models were tested: a single-beam model for stiffness periodicity every 90°, and a three-beam model for stiffness periodicity every 120°. Force responses, stress distribution, and sheet bending behaviors were analyzed, confirming that discrete beam elements can accurately represent direction-dependent stiffness. These results establish a foundation for developing advanced joint modeling strategies in complex mechanical systems.","lang":"eng"}],"status":"public","_id":"59441","project":[{"name":"TRR 285 – B01: TRR 285 - Subproject B01","_id":"140"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"130","name":"TRR 285: Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"department":[{"_id":"149"},{"_id":"9"},{"_id":"321"}],"user_id":"76837","language":[{"iso":"eng"}]},{"citation":{"ama":"Reckmann E, Temmen K.

A single case situational analysis reveals how standardized instrumental and music production practices are combined to form a hybrid practice. It shows that traditional music education institutions, such as music schools and conservatories, specialize in the selection of chord tones, while You-Tube videos focus on sound design. Using an actor-network theory approach, the study demonstrates the permeability of informal and institutional learning spaces.

This is partly due to missing powerful lead-free piezoelectric ceramic parts in the commercial market. There has been much research on lead-free materials but developing them into marketable parts seems to be an ongoing process. The actual exemption of ROHS has expired, but as the new exemption has already been requested, ceramic suppliers keep on selling lead containing products. Nevertheless, these should be replaced by lead-free alternatives for environmental and health issues. \r\nThis contribution focuses on exploring the technological readiness level of lead-free hard piezoceramics for prestressed ultrasonic transducers. A small series of bolted Langevin transducers was set up with standard PZT material and three commercial lead-free variants. Results of the building process from individual ring ceramic characteristics to transducer load tests are presented. The main finding of this study is that the lead-free materials technically can compete with the standard PZT for medium-power applications. Some adaptations in the ultrasonic system must be done: the geometry must be altered to fit resonance frequency, and higher voltages or thinner ceramics are needed to achieve the same vibration level at low load. For reaching same power, the volume of lead-free ceramics must be 1.5 to 3 times larger. As already promoted in literature, mechanical losses at high vibration levels are smaller for the lead-free materials. This might help to argument lead-free piezoelectric materials in some applications.\r\n\r\nReferences\r\n1.\tDirective 2011/65/EU of the European Parliament and of the Council of 8 June 2011 on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment.

At the beginning of the 1950s, the first ultrasonic cleaning devices finally came onto the market. Today, the range of applications ranges from household appliances for jewellery and eyewear cleaning to classic cleaning baths for metal parts and systems for cleaning highly sensitive electronic components. There is a certain gap in handheld, mobile cleaning equipment. Although devices for spot cleaning of textiles are known, the cleaning effect is usually low. \r\nDue to the directive 2011/65/EU on the restriction of the use of hazardous substances in electrical and electronic equipment (RoHS) [1] lead should no longer be used in technical devices. As today’s standard ceramics for medium and high-power ultrasonic transducers typically contain lead, there is a need to explore the use of lead-free ceramics in this field. Honda [2] already offers a cleaning transducer based on lead-free piezoelectric ceramics, but it is designed to be used in cleaning baths.\r\nThis article presents the model-based development of a highly innovative ultrasonic cleaner. On the one hand, lead-free piezoelectric ceramics are used, and on the other hand, a special sonotrode has been developed that concentrates the sound in such a way that a strong cavitation and thus cleaning effect is achieved with comparatively low power in a short time. Coupled field finite element method was used to find an appropriate geometry for the focussing sonotrode. The comparison of simulation and measurement results shows that the lead-free piezoceramics used do their job well and can keep up with standard ceramics, but more ceramic volume is needed to achieve same power. An advanced control concept was elaborated to ensure continuous hard cavitation at varying distances between the sonotrode and the part to be cleaned. Cleaning results for different surfaces and contaminations are presented. The concept of the focusing sonotrode shows that a convincing cleaning result can be achieved even with low power and in short time, provided that the oscillation system and control electronics are suitably coordinated.\r\n\r\nReferences\r\n[1] http://data.europa.eu/eli/dir/2011/65/2024-08-01 \r\n[2] https://en.honda-el.co.jp/product/ceramics/lineup/lead_off/lead-off \r\n"}],"type":"conference"},{"_id":"61755","project":[{"_id":"245","name":"FOR 5208: Modellbasierte Bestimmung nichtlinearer Eigenschaften von Piezokeramiken für Leistungsschallanwendungen (NEPTUN)"}],"department":[{"_id":"151"}],"user_id":"210","ddc":["620"],"language":[{"iso":"eng"}],"file_date_updated":"2026-03-02T10:59:53Z","type":"conference","status":"public","file":[{"content_type":"application/pdf","relation":"main_file","date_created":"2026-01-30T11:07:48Z","creator":"hemsel","date_updated":"2026-03-02T10:59:53Z","file_id":"63817","file_name":"SHS25_IWPMA_2025.pdf","access_level":"open_access","file_size":644147}],"date_updated":"2026-03-02T10:59:53Z","oa":"1","date_created":"2025-10-08T14:22:32Z","author":[{"first_name":"Claus","last_name":"Scheidemann","full_name":"Scheidemann, Claus","id":"38259"},{"first_name":"Tobias","id":"210","full_name":"Hemsel, Tobias","last_name":"Hemsel"},{"first_name":"Walter","full_name":"Sextro, Walter","id":"21220","last_name":"Sextro"}],"title":"Time dependent material characteristics of prestressed piezoelectric ceramics in langevin transducers","conference":{"end_date":"2025-07-3","location":"Vilnius, Lithuania","name":"22nd International Workshop on Piezoelectric Materials and Applications in Actuators (IWPMA)","start_date":"2025-07-1"},"has_accepted_license":"1","year":"2025","citation":{"ieee":"C.

The development of mechatronic systems is undergoing a similar transformation. Over the past decade, modeling, simulation, and optimization techniques have become integral to the design process, paving the way for the adoption of AI-based methods. In this paper, we examine the potential for integrating AI into the engineering design process, using the V-model from the VDI guideline 2206, considered the state-of-the-art in product design, as a foundation. We identify and classify AI methods based on their suitability for specific stages within the engineering product design workflow. Furthermore, we present a series of application examples where AI-assisted design has been successfully implemented by the authors. These examples, drawn from research projects within the DFG Priority Program \\emph{SPP~2353: Daring More Intelligence - Design Assistants in Mechanics and Dynamics}, showcase a diverse range of applications across mechanics and mechatronics, including areas such as acoustics and robotics.","lang":"eng"}],"type":"journal_article","publication":"Technische Mechanik - European Journal of Engineering Mechanics","doi":"10.24352/UB.OVGU-2025-037","title":"The impact of AI on engineering design procedures for dynamical systems","author":[{"full_name":"de Payrebrune, Kristin M.","last_name":"de Payrebrune","first_name":"Kristin M."},{"full_name":"Flaßkamp, Kathrin","last_name":"Flaßkamp","first_name":"Kathrin"},{"full_name":"Ströhla, Tom","last_name":"Ströhla","first_name":"Tom"},{"full_name":"Sattel, Thomas","last_name":"Sattel","first_name":"Thomas"},{"full_name":"Bestle, Dieter","last_name":"Bestle","first_name":"Dieter"},{"first_name":"Benedict","last_name":"Röder","full_name":"Röder, Benedict"},{"first_name":"Peter","full_name":"Eberhard, Peter","last_name":"Eberhard"},{"first_name":"Sebastian","last_name":"Peitz","full_name":"Peitz, Sebastian"},{"first_name":"Marcus","last_name":"Stoffel","full_name":"Stoffel, Marcus"},{"full_name":"Rutwik, Gulakala","last_name":"Rutwik","first_name":"Gulakala"},{"first_name":"Borse","last_name":"Aditya","full_name":"Aditya, Borse"},{"first_name":"Meike Claudia","last_name":"Wohlleben","orcid":"0009-0009-9767-7168","id":"43991","full_name":"Wohlleben, Meike Claudia"},{"last_name":"Sextro","full_name":"Sextro, Walter","id":"21220","first_name":"Walter"},{"first_name":"Maximilian","full_name":"Raff, Maximilian","last_name":"Raff"},{"last_name":"Remy","full_name":"Remy, C.
