The material responses of both the fiber and matrix are modeled using strain energy functions that account for damage evolution, while a complete linearization of the homogenization process is derived to ensure the consistent implementation of the Newton–Raphson iteration scheme in large deformation simulations. The innovative aspect of this work lies in the constitutive linearization for the hyperelastic-plastic-damage formulation within a mean-field homogenization framework, providing an efficient Newton algorithm for modeling the nonlinear behavior of CFRP. A failure criterion for the hyperelastic model of fibers is introduced, along with a damage saturation variable in rate form for the matrix, effectively capturing damage evolution.

To tackle this challenge, on the one hand, modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight design offers various possibilities. Multi-Material Design (MMD) involves designing car\r\nbodies that combine different materials that require joining. Given the variety of materials, mechanical joining\r\nprocesses are preferred. Especially the current development of the Giga/Mega-casting process concerning\r\naluminium casting and the subsequent mechanical joining illustrates the challenges of this material group. In car\r\nproduction, aluminium castings are mainly made from aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient ductility leads to crack initiation during mechanical joining. Cast parts are therefore often\r\nused in areas of the car body that are exposed to high-pressure loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure through tailored solidification rates and a developed heat-treatment chain strategy adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical, and joining properties are used to develop a\r\nsolidification-joining correlation for the SPR process across a range of Si contents and solidification rates. The\r\npurpose is to develop the ability to produce suitable aluminium castings with sufficient joinability, thereby\r\nimproving versatility.","lang":"eng"}],"author":[{"id":"32340","full_name":"Neuser, Moritz","last_name":"Neuser","first_name":"Moritz"},{"first_name":"Pia Katharina","full_name":"Kaimann, Pia Katharina","id":"44935","last_name":"Kaimann"},{"last_name":"Stratmann","full_name":"Stratmann, Ina","first_name":"Ina"},{"first_name":"Mathias","last_name":"Bobbert","full_name":"Bobbert, Mathias","id":"7850"},{"last_name":"Klöckner","full_name":"Klöckner, Johann Moritz Benedikt","first_name":"Johann Moritz Benedikt"},{"first_name":"Moritz","last_name":"Mann","full_name":"Mann, Moritz"},{"first_name":"Kay-Peter","full_name":"Hoyer, Kay-Peter","id":"48411","last_name":"Hoyer"},{"first_name":"Gerson","full_name":"Meschut, Gerson","id":"32056","orcid":"0000-0002-2763-1246","last_name":"Meschut"},{"first_name":"Mirko","full_name":"Schaper, Mirko","id":"43720","last_name":"Schaper"}],"volume":164,"date_updated":"2026-02-26T11:22:03Z","doi":"https://doi.org/10.1016/j.jmapro.2026.02.040","publication_status":"published","citation":{"chicago":"Neuser, Moritz, Pia Katharina Kaimann, Ina Stratmann, Mathias Bobbert, Johann Moritz Benedikt Klöckner, Moritz Mann, Kay-Peter Hoyer, Gerson Meschut, and Mirko Schaper. “Solidification-Joinability Correlation of Hypoeutectic Aluminium Casting Alloys for Self-Piercing Riveting (SPR).” <i>Journal of Manufacturing Processes</i> 164 (2026). <a href=\"https://doi.org/10.1016/j.jmapro.2026.02.040\">https://doi.org/10.1016/j.jmapro.2026.02.040</a>.","ieee":"M.

To achieve their maximum mechanical properties, the fiber-matrix adhesion (FMA) is critical. In this work, continuous fiber-reinforced thermoplastic laminates (CFRTPL) with a polypropylene (PP) matrix and twill woven glass fiber fabrics are produced by film stacking. The films used contain different amounts of maleic-anhydride-grafted PP (MA-g-PP) as a coupling agent to produce CFRTPL of different mechanical strengths. To analyze the FMA, the CFRTPL are subjected to Charpy-impact and tensile tests. Additionally, single fiber pull-out tests (SFPT) are conducted to further investigate the effect of MA-g-PP on the FMA. The results of the SFPT show an improvement in apparent interfacial shear strength (AIFSS) when the MA-g-PP content is increased, which can be attributed to an increase in FMA. However, the research shows that MA-g-PP has a low impact on the mechanical properties if the force is applied parallel to the warp and weft threads during tensile testing and the results of the Charpy-impact testing suffer from embrittlement of the matrix material. Subsequently, the results of this study are compared to three-point flexural tests conducted in a previous study. It can be concluded that tensile and impact tests are not suited to investigate FMA on a macroscopic scale, while SFPT and flexural tests provide a better alternative.</jats:p>"}]},{"status":"public","type":"journal_article","article_number":"e70093","user_id":"85414","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"_id":"65266","citation":{"apa":"Börger, A., Mahnken, R., Caylak, I., &#38; Ostwald, R.

To model this complex material behavior, a micromorphic continuum is used. In the present contribution, we focus on the linear‐elastic regime and demonstrate the identifiability of micromorphic material parameters under deliberately induced inhomogeneous deformation states. In addition to the degrees of freedom of a classical continuum, the micromorphic model has additional degrees of freedom, introduced here in a phenomenological sense to represent kinematically enriched deformation modes associated with the granular microstructure. Accordingly, the micromorphic fields are not interpreted as a separate physical scale (e.g., “binder” vs. “grains”), but as an effective continuum description at the specimen scale. This contribution addresses parameter identification for a micromorphic model of cold‐box sand, with a clear separation between homogeneous deformation states governing classical elastic parameters and inhomogeneous states required to activate and identify micromorphic length‐scale parameters. The main challenge lies in identifying the micro material parameters. To determine these, the corresponding gradient terms in the constitutive formulation must be triggered via properly tuned experiments. Micro‐parameter identification is demonstrated using synthetic data generated from a boundary‐value problem with inhomogeneous displacement fields. The chosen benchmark enables controlled activation of gradient terms and thereby renders optimization‐based identification of micromorphic parameters feasible. The synthetic example is deliberately chosen to assess feasibility and identifiability under controlled conditions, thereby isolating micromorphic identifiability aspects from experimental uncertainties. The novelty of the contribution lies in explicitly linking micromorphic parameter identifiability to kinematic inhomogeneity, and in demonstrating this link within a tractable forward– inverse setting for a linear‐elastic micromorphic continuum.</jats:p>"}],"publication":"Proceedings in Applied Mathematics and Mechanics","language":[{"iso":"eng"}],"year":"2026","issue":"2","quality_controlled":"1","title":"Aspects of Parameter Identification for a Micromorphic Continuum applied to a Cold‐Box Sand","date_created":"2026-04-01T04:52:34Z","publisher":"Wiley"},{"ddc":["620"],"language":[{"iso":"eng"}],"file_date_updated":"2026-04-18T07:19:12Z","_id":"65458","user_id":"57708","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"file":[{"file_name":"1-s2.0-S0997753826001233-main.pdf","file_id":"65459","access_level":"open_access","file_size":3153415,"creator":"ahamdoun","date_created":"2026-04-18T07:19:12Z","date_updated":"2026-04-18T07:19:12Z","relation":"main_file","content_type":"application/pdf"}],"status":"public","type":"journal_article","publication":"European Journal of Mechanics / A Solids","title":"A gradient-damage model for amorphous glassy polymers: Consistent formulation of viscoplasticity and damage evolution in a micromorphic framework","doi":"https://doi.org/10.1016/j.euromechsol.2026.106137","date_updated":"2026-04-20T11:28:43Z","oa":"1","author":[{"id":"57708","full_name":"Hamdoun, Ayoub","last_name":"Hamdoun","first_name":"Ayoub"},{"first_name":"Rolf","full_name":"Mahnken, Rolf","id":"335","last_name":"Mahnken"},{"id":"106876","full_name":"Ostwald, Richard","orcid":"0000-0003-2147-8444","last_name":"Ostwald","first_name":"Richard"}],"date_created":"2026-04-18T07:19:21Z","year":"2026","citation":{"bibtex":"@article{Hamdoun_Mahnken_Ostwald_2026, title={A gradient-damage model for amorphous glassy polymers: Consistent formulation of viscoplasticity and damage evolution in a micromorphic framework}, DOI={<a href=\"https://doi.org/10.1016/j.euromechsol.2026.106137\">https://doi.org/10.1016/j.euromechsol.2026.106137</a>}, journal={European Journal of Mechanics / A Solids}, author={Hamdoun, Ayoub and Mahnken, Rolf and Ostwald, Richard}, year={2026} }","short":"A.

Reuleaux triangle shaped clinched joints, in particular, show pronounced in-plane anisotropy depending on their orientation. While such effects have been studied at joint and specimen scale, their relevance at the structural level remains largely unexplored. In this work, the influence of joint orientation on the bending response of a joined structure is investigated using numerical simulations. A simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector formulation in LS-DYNA is employed, with parameters calibrated from previously obtained experimental force displacement data. A hat shaped profile structure subjected to three-point bending is analyzed in a parametric study considering variations in joint orientation, joint spacing, and profile geometry. The results show that joint orientation has little influence during the initial deformation phase but becomes increasingly significant at larger displacements, where joint behavior governs load transfer. Orientation dependent effects are found to influence the global force displacement response and local load redistribution among joints, with magnitudes comparable to those induced by changes in joint spacing and structural geometry. The findings confirm that joint orientation effects remain relevant at the structural level and should be considered in the design of structures assembled using non-rotationally symmetric clinched joints.</jats:p>"}],"status":"public","date_updated":"2026-04-22T08:30:15Z","publisher":"Trans Tech Publications, Ltd.","volume":1185,"author":[{"first_name":"Deekshith Reddy","full_name":"Devulapally, Deekshith Reddy","last_name":"Devulapally"},{"full_name":"Tröster, Thomas","last_name":"Tröster","first_name":"Thomas"}],"date_created":"2026-04-22T08:19:27Z","title":"A Numerical Study on the Mutual Influence of Joint Orientation and Component Geometry in Non-Rotationally Symmetric Clinched Joints","doi":"10.4028/p-0tiihi","publication_identifier":{"issn":["1662-9752"]},"publication_status":"published","year":"2026","page":"161-169","intvolume":"      1185","citation":{"ama":"Devulapally DR, Tröster T.

With the micropolar model, size effects can be considered and the boundary value problem can be regularized when localization effects occur. In order to map the microrotations, an additional strain measure and an additional stress are introduced. For simulation of plasticity, it is possible to define one yield function, and thus one plastic multiplier as well as one equivalent plastic strain occur. This approach is known as the single-surface plasticity approach. The macro- and micro-stresses are coupled in a common flow function. On the other hand, there is the so-called double-surface plasticity when one yield function, one plastic multiplier, and one equivalent plastic strain, respectively, are introduced for each of the macro- and micro-variables. The coupling of the macro- and micro-variables is established by a possible coupling of both yield functions.

Hierzu bedarf es einer umfassenden Mobilitätswende, welche die Etablierung emissionsärmerer und effizienterer Mobilitätsformen umfasst. Ein Lösungsansatz können on-demand Dienste bieten, die den öffentlichen Personennahverkehr bedarfsgerecht gestalten und so dessen Akzeptanz steigern. Zahlreiche bisher eingeführte on-demand Dienste mussten jedoch nach Beendigung des Projekt- bzw. Förderzeitraums wieder eingestellt werden. Maßgebliche Herausforderungen waren die Integration der Dienste in die bestehenden ÖPNV- und Mobilitäts-Strukturen sowie teilweise damit einhergehende ökonomische Aspekte. In diesem Beitrag wird eine Methode vorgestellt, welche neben der Einführung neuartiger Mobilitätsdienste auch die Entwicklung eines nachhaltigen Mobilitäts-Ökosystems anstrebt. Der Fokus liegt dabei auf ländlich geprägten Regionen und ihren besonderen Herausforderungen im Bereich des öffentlichen Nahverkehrs. Die Methode beschreibt ein fünf-phasiges Handlungsschema, in welchem Potenziale bestehender Strukturen genutzt, Mobilitäts-Stakeholder eingebunden und verhärtete Mobilitätsverhalten allmählich positiv verändert werden. Anhand der Initiative Neue Mobilität Paderborn wird aufgezeigt, dass mithilfe der Methode erste Schritte hin zu einem Mobilitäts-Ökosystem absolviert werden können. Darüber hinaus werden Einführungsszenarien für die neuartige, sich noch in der Entwicklung befindliche Mobilitätslösung NeMo.bil in einer Beispielregion erarbeitet."}],"status":"public","_id":"59905","user_id":"44763","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"language":[{"iso":"ger"}],"publication_status":"published","publication_identifier":{"isbn":["9783658464844","9783658464851"]},"place":"Wiesbaden","year":"2025","citation":{"ieee":"J.
