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"],"language":[{"iso":"eng"}]},{"date_created":"2024-04-23T08:20:05Z","author":[{"last_name":"Dornbusch","full_name":"Dornbusch, Daniel","first_name":"Daniel"},{"full_name":"Hanke, Marcel","last_name":"Hanke","first_name":"Marcel"},{"first_name":"Emilia","id":"68157","full_name":"Tomm, Emilia","last_name":"Tomm"},{"last_name":"Kielar","full_name":"Kielar, Charlotte","first_name":"Charlotte"},{"first_name":"Guido","last_name":"Grundmeier","full_name":"Grundmeier, Guido","id":"194"},{"first_name":"Adrian","orcid":"0000-0001-7139-3110","last_name":"Keller","id":"48864","full_name":"Keller, Adrian"},{"first_name":"Karim","full_name":"Fahmy, Karim","last_name":"Fahmy"}],"publisher":"Royal Society of Chemistry (RSC)","date_updated":"2024-04-23T08:21:05Z","doi":"10.1039/d3cc05985e","title":"Cold denaturation of DNA origami nanostructures","publication_status":"published","publication_identifier":{"issn":["1359-7345","1364-548X"]},"citation":{"mla":"Dornbusch, Daniel, et al. “Cold Denaturation of DNA Origami Nanostructures.” <i>Chemical Communications</i>, Royal Society of Chemistry (RSC), 2024, doi:<a href=\"https://doi.org/10.1039/d3cc05985e\">10.1039/d3cc05985e</a>.","short":"D.

To capture this in simulations, intricate models with a variety of parameters are typically used. The identification of values for such parameters is highly challenging and requires in depth understanding of the model itself. Machine learning (ML) is a promising approach for alleviating this challenge by directly predicting parameters based on experimental results. So far, this works mostly for purely artificial data. In this work, two approaches to generalize to experimental data are investigated: a sequential approach, leveraging understanding of the constitutive model and a direct, purely data driven approach. This is exemplary carried out for a highly non-linear strain rate dependent constitutive model for the shear behavior of FRP.The sequential model is found to work better on both artificial and experimental data. It is capable of extracting well suited parameters from the artificial data under realistic conditions. For the experimental data, the model performance depends on the composition of the experimental curves, varying between excellently suiting and reasonable predictions. Taking the expert knowledge into account for ML-model training led to far better results than the purely data driven approach. Robustifying the model predictions on experimental data promises further improvement.

However, a decisive disadvantage of these composite materials has so far been the high material and process costs, which is why fiber-reinforced plastics are almost exclusively used in small to medium-sized series. Optimization of manufacturing methods is of great importance to reduce the production cost. In this study, two concepts are proposed that can optimize vacuum assisted light resin transfer molding (VA-LRTM) further, leading to a possibility of fully automatic process. Conventional VA-LRTM methods are used to produce complex fiber-reinforced plastics (FRP) and hybrid components. Traditional molds used to produce components via VA-LRTM are sealed using polymer materials to prevent the leakage of matrix system. The seals undergo tremendous amounts of thermal, chemical, and mechanical loadings. Thus, sealings must be replaced in short intervals. In the current study, a concept where sealing is achieved by accelerating the curing of matrix system itself with the help of heating elements and catalysts resulting in a self-sealing approach is proposed. Another concern is mold surface contamination during component production. To address this, a modified automatic cleaning technique based on ultrasonic cleaning was proposed which can be integrated into the production line with minimum modification. Both the proposed concepts were validated and optimized using experiments, simulations, and analytical approaches by producing metal-FRP hybrid shafts.","lang":"eng"}],"file":[{"content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2024-01-11T09:24:01Z","date_created":"2024-01-11T09:24:01Z","creator":"dcj","file_size":7694237,"access_level":"closed","file_id":"50451","file_name":"01_Dissertation_CJDP_7065653_V1.pdf"}],"status":"public","type":"dissertation","title":"Advances In RTM Manufacturing Of Metal-FRP Hybrids By Self-Sealing And In-Mold Cleaning Techniques","date_updated":"2024-03-26T09:18:31Z","date_created":"2024-01-11T09:28:04Z","author":[{"first_name":"Deviprasad","last_name":"Chalicheemalapalli Jayasankar","orcid":"https://orcid.org/ 0000-0002-3446-2444","id":"49504","full_name":"Chalicheemalapalli Jayasankar, Deviprasad"}],"supervisor":[{"last_name":"Tröster","full_name":"Tröster, Thomas","first_name":"Thomas"},{"first_name":"Wolfgang","full_name":"Bremser, Wolfgang","last_name":"Bremser"}],"year":"2023","citation":{"ama":"Chalicheemalapalli Jayasankar D. <i>Advances In RTM Manufacturing Of Metal-FRP Hybrids By Self-Sealing And In-Mold Cleaning Techniques</i>.; 2023.","ieee":"D.

In combination with additive manufacturing, which facilitates great flexibility of the implant design, it is possible to selectively adjust the microstructure of the material in the process, thereby control the corrosion and fatigue behavior. In the present study, conventional hot-rolled (HR) pure iron is compared to pure iron manufactured by electron beam melting (EBM). The microstructure, the corrosion behavior and the fatigue properties were studied comprehensively. The investigated sample conditions showed significant differences in the microstructures that led to changes in corrosion and fatigue properties. The EBM iron showed significantly lower fatigue strength compared to the HR iron. These different fatigue responses were observed under purely mechanical loading as well as with superimposed corrosion influence and are summarized in a model that describes the underlying failure mechanisms.</jats:p>","lang":"eng"}],"publication":"npj Materials Degradation","type":"journal_article","doi":"10.1038/s41529-022-00226-4","title":"Corrosion fatigue behavior of electron beam melted iron in simulated body fluid","volume":6,"author":[{"last_name":"Wackenrohr","full_name":"Wackenrohr, Steffen","first_name":"Steffen"},{"full_name":"Torrent, Christof Johannes Jaime","last_name":"Torrent","first_name":"Christof Johannes Jaime"},{"first_name":"Sebastian","last_name":"Herbst","full_name":"Herbst, Sebastian"},{"full_name":"Nürnberger, Florian","last_name":"Nürnberger","first_name":"Florian"},{"last_name":"Krooss","full_name":"Krooss, Philipp","first_name":"Philipp"},{"last_name":"Ebbert","full_name":"Ebbert, Christoph","first_name":"Christoph"},{"full_name":"Voigt, Markus","id":"15182","last_name":"Voigt","first_name":"Markus"},{"full_name":"Grundmeier, Guido","id":"194","last_name":"Grundmeier","first_name":"Guido"},{"full_name":"Niendorf, Thomas","last_name":"Niendorf","first_name":"Thomas"},{"full_name":"Maier, Hans Jürgen","last_name":"Maier","first_name":"Hans Jürgen"}],"date_created":"2022-04-20T07:55:17Z","date_updated":"2022-04-20T07:59:08Z","publisher":"Springer Science and Business Media LLC","intvolume":"         6","citation":{"ieee":"S.

An Iosipescu testing setup on a servo-hydraulic high speed testing unit is used to experimentally characterise the in-plane and out-of-plane behaviour utilising three specimen configurations (12-, 13- and 31-direction). The experimental procedure as well as the testing results are presented and discussed. The measured shear stress–shear strain relations indicate a highly nonlinear behaviour and a distinct rate dependency. Two methods are investigated to derive according material characteristics: a classical engineering approach based on moduli and strengths and a data driven approach based on the curve progression. In all cases a Johnson–Cook based formulation is used to describe rate dependency. The analysis methodologies as well as the derived model parameters are described and discussed in detail. It is shown that a phenomenologically enhanced regression can be used to obtain material characteristics for a generalising constitutive model based on the data driven approach.</jats:p>","lang":"eng"}],"keyword":["Engineering (miscellaneous)","Ceramics and Composites"],"language":[{"iso":"eng"}],"issue":"10","year":"2022","publisher":"MDPI AG","date_created":"2022-12-06T20:42:38Z","title":"A Data Driven Modelling Approach for the Strain Rate Dependent 3D Shear Deformation and Failure of Thermoplastic Fibre Reinforced Composites: Experimental Characterisation and Deriving Modelling Parameters"},{"doi":"10.1088/1361-6668/ac5338","author":[{"id":"46170","full_name":"Protte, Maximilian","last_name":"Protte","first_name":"Maximilian"},{"last_name":"Verma","full_name":"Verma, Varun B","first_name":"Varun B"},{"first_name":"Jan Philipp","last_name":"Höpker","full_name":"Höpker, Jan Philipp","id":"33913"},{"first_name":"Richard P","full_name":"Mirin, Richard P","last_name":"Mirin"},{"full_name":"Woo Nam, Sae","last_name":"Woo Nam","first_name":"Sae"},{"full_name":"Bartley, Tim","id":"49683","last_name":"Bartley","first_name":"Tim"}],"volume":35,"date_updated":"2023-01-12T13:02:52Z","citation":{"mla":"Protte, Maximilian, et al. “Laser-Lithographically Written Micron-Wide Superconducting Nanowire Single-Photon Detectors.” <i>Superconductor Science and Technology</i>, vol. 35, no. 5, 055005, IOP Publishing, 2022, doi:<a href=\"https://doi.org/10.1088/1361-6668/ac5338\">10.1088/1361-6668/ac5338</a>.","bibtex":"@article{Protte_Verma_Höpker_Mirin_Woo Nam_Bartley_2022, title={Laser-lithographically written micron-wide superconducting nanowire single-photon detectors}, volume={35}, DOI={<a href=\"https://doi.org/10.1088/1361-6668/ac5338\">10.1088/1361-6668/ac5338</a>}, number={5055005}, journal={Superconductor Science and Technology}, publisher={IOP Publishing}, author={Protte, Maximilian and Verma, Varun B and Höpker, Jan Philipp and Mirin, Richard P and Woo Nam, Sae and Bartley, Tim}, year={2022} }","short":"M.

In addition to the extrusion of decking boards, the material is also used increasingly in injection molding. Depending on the formulation, geometry and process parameters, WPC tends to exhibit irregular filling behavior, similar to the processing of thermosets. In this work, the influence of matrix material and wood fiber content on the flow, mold filling and segregation behavior of WPC is analyzed. For this purpose, investigations were carried out on a flow spiral and a sheet cavity. WPC based on thermoplastic polyurethane (TPU) achieves significantly higher flow path lengths at a wood mass content of 30% than polypropylene (PP)-based WPC. The opposite behavior occurs at higher wood contents due to the different shear thinning behavior. Slightly decreased wood contents could be observed at the beginning of the flow path and greatly increased wood contents at the end of the flow path, compared to the starting material. When using the plate cavity, flow anomalies in the form of free jets occur as a function of the wood content, with TPU exhibiting the more critical behavior. The flow front is frayed, but in contrast to the flow spiral, no significant wood accumulation could be detected due to the shorter flow path lengths.</jats:p>","lang":"eng"}],"publisher":"MDPI AG","date_created":"2022-10-21T05:57:03Z","title":"Analysis of the Segregation Phenomena of Wood Fiber Reinforced Plastics","quality_controlled":"1","issue":"10","year":"2022","_id":"33856","user_id":"38212","department":[{"_id":"321"},{"_id":"9"},{"_id":"367"},{"_id":"147"}],"article_number":"321","type":"journal_article","status":"public","oa":"1","date_updated":"2023-04-26T13:40:41Z","author":[{"first_name":"Elmar","full_name":"Moritzer, Elmar","id":"20531","last_name":"Moritzer"},{"first_name":"Felix","full_name":"Flachmann, Felix","id":"38212","orcid":"0000-0002-7651-7028","last_name":"Flachmann"},{"first_name":"Maximilian","last_name":"Richters","id":"38221","full_name":"Richters, Maximilian"},{"first_name":"Marcel","last_name":"Neugebauer","full_name":"Neugebauer, Marcel"}],"volume":6,"main_file_link":[{"open_access":"1"}],"doi":"10.3390/jcs6100321","publication_status":"published","publication_identifier":{"issn":["2504-477X"]},"citation":{"chicago":"Moritzer, Elmar, Felix Flachmann, Maximilian Richters, and Marcel Neugebauer. “Analysis of the Segregation Phenomena of Wood Fiber Reinforced Plastics.” <i>Journal of Composites Science</i> 6, no. 10 (2022). <a href=\"https://doi.org/10.3390/jcs6100321\">https://doi.org/10.3390/jcs6100321</a>.","ieee":"E.

The stacking sequence of the unidirectional plies forming a CFRP laminate, and their thicknesses, primarily determine the mechanical performance. However, during manufacturing, defects, e.g., pores and residual stresses, are induced, both affecting the mechanical properties. The objective of the present work is to accurately measure residual stresses in CFRPs as well as to investigate the effects of stacking sequence, overall laminate thickness, and the presence of pores on the residual stress state. Residual stresses were measured through the incremental hole-drilling method (HDM). Adequate procedures have been applied to evaluate the residual stresses for orthotropic materials, including calculating the calibration coefficients through finite element analysis (FEA) based on stacking sequence, laminate thickness and mechanical properties. Using optical microscopy (OM) and computed tomography (CT), profound insights into the cross-sectional and three-dimensional microstructure, e.g., location and shape of process-induced pores, were obtained. This microstructural information allowed for a comprehensive understanding of the experimentally determined strain and stress results, particularly at the transition zone between the individual plies. The effect of pores on residual stresses was investigated by considering pores to calculate the calibration coefficients at a depth of 0.06 mm to 0.12 mm in the model and utilizing these results for residual stress evaluation. A maximum difference of 46% in stress between defect-free and porous material sample conditions was observed at a hole depth of 0.65 mm. The significance of employing correctly calculated coefficients for the residual stress evaluation is highlighted by mechanical validation tests.</jats:p>"}],"language":[{"iso":"eng"}],"keyword":["Engineering (miscellaneous)","Ceramics and Composites"],"issue":"5","quality_controlled":"1","year":"2022","date_created":"2022-05-30T07:04:34Z","publisher":"MDPI AG","title":"Experimental Analysis of Residual Stresses in CFRPs through Hole-Drilling Method: The Role of Stacking Sequence, Thickness, and Defects","type":"journal_article","status":"public","department":[{"_id":"149"},{"_id":"321"}],"user_id":"72722","_id":"31496","funded_apc":"1","article_number":"138","publication_identifier":{"issn":["2504-477X"]},"publication_status":"published","intvolume":"         6","citation":{"chicago":"Wu, Tao, Roland Kruse, Steffen Rainer Tinkloh, Thomas Tröster, Wolfgang Zinn, Christian Lauhoff, and Thomas Niendorf. “Experimental Analysis of Residual Stresses in CFRPs through Hole-Drilling Method: The Role of Stacking Sequence, Thickness, and Defects.” <i>Journal of Composites Science</i> 6, no. 5 (2022). <a href=\"https://doi.org/10.3390/jcs6050138\">https://doi.org/10.3390/jcs6050138</a>.","ieee":"T.
