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.","lang":"eng"}],"publication":"Sheet Metal 2025","keyword":["Finite Element Method (FEM)","Process","Thermoplastic Fiber Reinforced Plastic"],"language":[{"iso":"eng"}],"page":"268–275","citation":{"apa":"Gröger, B., Gerritzen, J., Hornig, A., &#38; Gude, M.

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."}],"series_title":"Materials Research Proceedings","user_id":"105344","project":[{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"name":"TRR 285 - Subproject A03","_id":"137"},{"_id":"131","name":"TRR 285 - Project Area A"}],"_id":"62080","language":[{"iso":"eng"}],"keyword":["Failure","Fiber Reinforced Plastic","Machine Learning"],"publication_identifier":{"isbn":["978-1-64490-354-4"]},"citation":{"ama":"Gerritzen J, Hornig A, Gude M.

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."}],"publication":"Proceedings of the 8th International Conference on Integrity-Reliability-Failure (IRF2025)"},{"article_number":"100368","language":[{"iso":"eng"}],"_id":"63828","project":[{"name":"TRR 285 - Subproject A03","_id":"137"},{"_id":"131","name":"TRR 285 - Project Area A"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"_id":"133","name":"TRR 285 - Project Area C"},{"name":"TRR 285 - Subproject C04","_id":"148"}],"user_id":"105344","status":"public","publication":"Journal of Advanced Joining Processes","type":"journal_article","title":"Quality assurance of clinched joints using explainable machine learning","doi":"10.1016/j.jajp.2025.100368","publisher":"Elsevier BV","date_updated":"2026-02-27T06:45:47Z","volume":13,"date_created":"2026-02-02T08:32:04Z","author":[{"first_name":"Johannes","id":"105344","full_name":"Gerritzen, Johannes","orcid":"0000-0002-0169-8602","last_name":"Gerritzen"},{"first_name":"Kunal","full_name":"Chopra, Kunal","last_name":"Chopra"},{"last_name":"Reschke","full_name":"Reschke, Gregor","id":"98812","first_name":"Gregor"},{"last_name":"Hornig","full_name":"Hornig, Andreas","first_name":"Andreas"},{"first_name":"Alexander","full_name":"Brosius, Alexander","last_name":"Brosius"},{"first_name":"Maik","last_name":"Gude","full_name":"Gude, Maik"}],"year":"2025","intvolume":"        13","citation":{"ama":"Gerritzen J, Chopra K, Reschke G, Hornig A, Brosius A, Gude M.

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.</jats:p>"}],"type":"conference","publication":"Materials Research Proceedings","language":[{"iso":"eng"}],"user_id":"76837","department":[{"_id":"149"},{"_id":"9"},{"_id":"321"}],"project":[{"_id":"140","name":"TRR 285 – B01: TRR 285 - Subproject B01"},{"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"}],"_id":"59441"},{"department":[{"_id":"300"}],"user_id":"101166","_id":"62041","language":[{"iso":"eng"}],"publication":"EDULEARN Proceedings","type":"conference","status":"public","editor":[{"last_name":"Gómez Chova","full_name":"Gómez Chova, Luis ","first_name":"Luis "},{"first_name":"Chelo","last_name":"González Martínez","full_name":"González Martínez, Chelo"},{"full_name":"Lees, Joanna","last_name":"Lees","first_name":"Joanna"}],"volume":1,"author":[{"id":"101166","full_name":"Reckmann, Eileen","last_name":"Reckmann","first_name":"Eileen"},{"first_name":"Katrin","last_name":"Temmen","full_name":"Temmen, Katrin","id":"30086"}],"date_created":"2025-11-03T09:25:42Z","date_updated":"2026-02-27T11:17:10Z","publisher":"IATED","doi":"10.21125/edulearn.2025.2462","title":"Intrinsic Motivation in Stem Outreach: An Analysis of External Factors in Voluntary and School-Based Lab Settings","publication_identifier":{"issn":["2340-1117"]},"publication_status":"published","intvolume":"         1","citation":{"apa":"Reckmann, E., &#38; Temmen, K.

It investigates a didactic design that was implemented in six schools and was empirically researched utilizing si-tuational analysis. Based on tensions, that emerge due to conflicting expectations, it can be shown, that the teacher's role extends beyond the dichotomy of directive instruction versus open facilitation. Instead, it encompasses an interplay of six divergent roles which are discussed in their positions in relation to each other. These considerations enrich the understanding of teaching practices in popular music education, emphasizing the redefinition of teacher-student relationships for song-writing in school music.","lang":"eng"}],"author":[{"last_name":"Godau","full_name":"Godau, Marc","id":"98877","first_name":"Marc"},{"last_name":"Barreiro","full_name":"Barreiro, Julia","first_name":"Julia"},{"last_name":"Hermann","full_name":"Hermann, Katharina","first_name":"Katharina"},{"full_name":"Neuhausen, Timo","id":"99991","orcid":"0000-0002-8262-767X","last_name":"Neuhausen","first_name":"Timo"},{"last_name":"Maxelon","full_name":"Maxelon, Dominik","first_name":"Dominik"},{"first_name":"Verena","full_name":"Weidner, Verena","last_name":"Weidner"}],"date_created":"2026-02-28T09:50:45Z","date_updated":"2026-02-28T15:29:25Z","publisher":"Waxmann","oa":"1","main_file_link":[{"open_access":"1"}],"doi":"10.31244/9783818850715.13","title":"\"Wofür bin ich denn hier, wenn ich nicht in irgendeiner Weise auch helfen kann?\" Zur Rolle der Lehrkraft beim selbstständigen Songwriting im Unterricht","publication_status":"published","quality_controlled":"1","publication_identifier":{"isbn":["9783818800710"]},"citation":{"ama":"Godau M, Barreiro J, Hermann K, Neuhausen T, Maxelon D, Weidner V. “Wofür bin ich denn hier, wenn ich nicht in irgendeiner Weise auch helfen kann?” Zur Rolle der Lehrkraft beim selbstständigen Songwriting im Unterricht.

On the socio-materiality of songwriting-producing in the bedroom studio This study examines the socio-materiality of hybrid music practices in bedroom studios, focusing on the interplay between traditional music education institutions and YouTube education. 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. The findings suggest that songwriting-producing is not simply a sum of different practices, but rather a process of negotiation and compromise between different standards and goals, as well as the distribution of practice between humans and technology."}],"publication":"46.
