To overcome\r\nthermal imbalance constraints, an innovative strategy leveraging plastic shell containment is proposed to elevate\r\nthe expulsion-free heat input threshold. By applying a combined preheating and ramping current profile, a coordinated “shell-first, nugget-second” sequence is achieved. This mechanism creates a solid-state barrier prior to\r\nrapid fusion, effectively preventing expulsion. Experimental results demonstrate that while the reference\r\nconstant-current schedule fails to maintain a process window under a 2 mm initial gap (IG) disturbance, the\r\nproposed strategy significantly enhances process stability. It increases the maximum expulsion-free heat input by\r\n24 % (to 6338 J) under normal conditions and by 77 % (to 6482 J) under the IG condition. Crucially, the\r\nincreased heat input drives nugget growth across all interfaces, achieving a penetration depth of 0.38 mm (48 %\r\npenetration ratio) in the low-carbon steel sheet under the gap condition. These findings validate the strategy’s\r\neffectiveness in ensuring weld quality and robustness, which is further confirmed by its transferability to a lowerresistivity DX54D cover sheet."}],"publication":"Journal of Manufacturing Processes","title":"Process window expansion with transferable applicability in three-layer dissimilar steel resistance spot welding via expulsion prevention","date_created":"2025-12-22T08:20:34Z","publisher":"Elsevier BV","year":"2026","issue":"Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.","quality_controlled":"1"},{"file_date_updated":"2025-12-26T13:42:22Z","article_type":"original","department":[{"_id":"157"}],"user_id":"65085","_id":"63418","status":"public","type":"journal_article","doi":"10.1016/j.jmapro.2025.12.058","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S1526612525013787?via%3Dihub","open_access":"1"}],"volume":157,"author":[{"last_name":"Olfert","id":"5974","full_name":"Olfert, Viktoria","first_name":"Viktoria"},{"first_name":"Keke","id":"65085","full_name":"Yang, Keke","last_name":"Yang","orcid":"0000-0001-9201-9304"},{"full_name":"Rochel, Philip","last_name":"Rochel","first_name":"Philip"},{"full_name":"Bähr, Philipp","last_name":"Bähr","first_name":"Philipp"},{"first_name":"David","id":"7728","full_name":"Hein, David","last_name":"Hein"},{"first_name":"Silke","last_name":"Sommer","full_name":"Sommer, Silke"},{"id":"32056","full_name":"Meschut, Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","first_name":"Gerson"}],"date_updated":"2025-12-26T14:06:38Z","oa":"1","intvolume":"       157","page":"1250-1273","citation":{"short":"V.

This study establishes a validated hierarchical methodology to predict tolerance-dependent failure behavior of SPR joints, progressing from coupon to sub-component scale through an integrated experimental–numerical approach. Five critical manufacturing tolerances, including rivet length (±0.5 mm), rivet head position (±0.3 mm), orthogonality deviation (2.8° and 5°), lateral offset (up to 1.2 mm), and flange overlap reduction (up to 7.5 mm), were investigated. Steel–steel joints exhibited a higher sensitivity to tolerances by a factor of 2–3 compared to steel–aluminum joints. A unified effective rivet length concept was developed to consolidate the geometric effects of all tolerances into a single physically meaningful parameter, enabling load-bearing capacity prediction with R2 > 0.95 across all evaluated loading directions. The sub-component validation employing T-joint specimens indicates a 2–3 fold amplification of tolerance effects at critical structural regions, providing experimental evidence for the hierarchical scaling principle. The methodology was implemented in a tolerance-dependent CONSTRAINED_SPR3 formulation, providing >99 % computational efficiency improvement while maintaining a deviation in maximum force prediction within ±7 %. This framework enables the physically consistent representation of manufacturing variation within large-scale simulations and establishes a transferable basis for tolerance-resilient virtual vehicle development."}],"publication":"Journal of Manufacturing Processes","title":"Predictive modeling of tolerance-dependent failure behavior of self-pierce riveted joints: From coupon-level tests to sub-component validation","date_created":"2025-12-26T13:41:43Z","publisher":"Elsevier BV","year":"2026","issue":"Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.","quality_controlled":"1"},{"type":"journal_article","status":"public","department":[{"_id":"157"}],"user_id":"65085","_id":"58535","file_date_updated":"2025-02-07T10:09:17Z","has_accepted_license":"1","publication_identifier":{"issn":["1526-6125"]},"publication_status":"published","page":"306-319","intvolume":"       137","citation":{"apa":"Yang, K., Wang, Z., Haak, V., Olfert, V., El-Sari, B., Hein, D., Biegler, M., Rethmeier, M., &#38; Meschut, G.

Liquid Metal Embrittlement (LME) cracking is a well-documented issue encountered during resistance spot welding (RSW) of zinc-coated advanced high-strength steels (AHSS) in automotive manufacturing. Given that existing research has predominantly focused on laboratory-scale samples and lacks investigation into the load-bearing capacity of joints under crash conditions, this study aims to fill these gaps by analyzing third-generation zinc-coated AHSS. S-Rail components were produced through stamping to replicate real-world manufacturing conditions and geometries of automotive parts. To account for the disturbances typically encountered in production, samples with LME cracks were intentionally fabricated. Subsequently, a modified three-point bending test, assisted by numerical simulations, was developed to effectively apply loads to the weld spots of the S-Rail components. Results from crash tests demonstrated that observed light crack severity does not significantly compromise the joint's load-bearing capacity or lead to earlier joint failure.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"ddc":["600"],"quality_controlled":"1","year":"2025","date_created":"2025-03-25T07:59:49Z","publisher":"Materials Research Forum LLC","title":"Influence of Liquid metal embrittlement on load-bearing capacity of resistance spot welds under crash loads: A study based on S-Rail components"},{"publication_identifier":{"issn":["2474-395X"]},"publication_status":"published","intvolume":"        54","citation":{"mla":"Olfert, Viktoria, et al. “Analysis of Fatigue Behaviour of Self-Piercing Riveted Joints under Cyclic Loading Using Laser Vibrometry.” <i>Materials Research Proceedings</i>, vol. 54, Materials Research Forum LLC, 2025, doi:<a href=\"https://doi.org/10.21741/9781644903599-154\">10.21741/9781644903599-154</a>.","short":"V.

In the field of online condition monitoring, non-destructive testing methods using active acoustic testing [1] emerged as innovative tools. These techniques are particularly effective because damage in joined structures leads to significant changes in their vibrational characteristics. However, the consistent use of online condition monitoring through active acoustic testing combined with complex pattern recognition for early crack detection in joined components has not yet been fully established. This research aims to develop an online crack detection system employing pattern recognition techniques under cyclic loading during fatigue tests, utilizing non-contact active acoustic testing with laser vibrometry. Due to the wide range of materials that can be joined, mechanical joining processes can be used in many different industry branches. Self-pierce riveting (SPR), in particular, is a well-established joining process. Therefore, the investigations for online crack detection initially focus on SPR joints. To achieve this, the fatigue behavior of SPR joints in a lap-shear configuration was characterized. Experimental fatigue testing demonstrated that SPR joint failure occurs either through cracks propagating in the sheet material away from the rivet or in the rivet foot, depending on the material combination. Laser vibrometry has been successfully used as a crack detection system and has proven to be effective in detecting crack initiation in SPR joints. Cracks can be detected without contact regardless of the material combination, the damage location, the size of the damage, or the type of damage.  The optimization of the crack detection system involved several key enhancements, including adjusting data acquisition to improve crack detection, incorporating principal component analysis (PCA) to reduce dimensionality, and implementing a classification model based on a global training dataset. An intuitive, problem-specific software demonstrator for analyzing the crack initiation behavior of SPR joints under cyclic loading was developed and iteratively optimized. Future work will focus on the implementation of an autoencoder network to further enhance crack detection capabilities.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}]},{"publisher":"Wiley","date_updated":"2024-03-18T12:49:31Z","date_created":"2024-01-22T09:17:07Z","author":[{"first_name":"Lilia","full_name":"Schuster, Lilia","last_name":"Schuster"},{"first_name":"Viktoria","full_name":"Olfert, Viktoria","id":"5974","last_name":"Olfert"},{"full_name":"Sherepenko, Oleksii","last_name":"Sherepenko","first_name":"Oleksii"},{"full_name":"Fehrenbach, Clemens","last_name":"Fehrenbach","first_name":"Clemens"},{"first_name":"Shiyuan","last_name":"Song","full_name":"Song, Shiyuan"},{"first_name":"David","id":"7728","full_name":"Hein, David","last_name":"Hein"},{"first_name":"Gerson","full_name":"Meschut, Gerson","id":"32056","orcid":"0000-0002-2763-1246","last_name":"Meschut"},{"first_name":"Elliot","last_name":"Biro","full_name":"Biro, Elliot"},{"full_name":"Münstermann, Sebastian","last_name":"Münstermann","first_name":"Sebastian"}],"title":"Influences of Weld Nugget Shape and Material Gradient on the Shear Strength of Resistance Spot‐Welded Joints","doi":"10.1002/srin.202300530","publication_status":"published","publication_identifier":{"issn":["1611-3683","1869-344X"]},"quality_controlled":"1","year":"2024","citation":{"chicago":"Schuster, Lilia, Viktoria Olfert, Oleksii Sherepenko, Clemens Fehrenbach, Shiyuan Song, David Hein, Gerson Meschut, Elliot Biro, and Sebastian Münstermann. “Influences of Weld Nugget Shape and Material Gradient on the Shear Strength of Resistance Spot‐Welded Joints.” <i>Steel Research International</i>, 2024. <a href=\"https://doi.org/10.1002/srin.202300530\">https://doi.org/10.1002/srin.202300530</a>.","ieee":"L.

The effect of weld nugget shape and material property gradients is studied based on damage mechanics modeling and experimental validation to shed light on the underlying influencing factors. For a three‐steel‐sheet spot‐welded joint combining DP600 (1.5 mm)–CR1900T (1.0 mm)–CR1900T (1.0 mm), experiments under shear loading reveal that fracture occurs in the DP600 sheet along the weld nugget edge. In subsequent numerical simulation studies with damage mechanics models whose parameters are independently calibrated for every involved material configuration, three variations of the geometrical joint configuration are considered—an approximation of the real joint, one variation with a steeper weld nugget shape, and one variation with a less pronounced gradient between weld nugget material and heat‐affected zone material properties. The results of the finite‐element simulations show that a shallower weld nugget and a more pronounced material gradient lead to a faster increase of plastic strain at the edge of the weld nugget and promote the occurrence of total dome failure.</jats:p>"}],"status":"public"},{"_id":"58382","user_id":"30228","department":[{"_id":"157"}],"language":[{"iso":"ger"}],"type":"conference_abstract","publication":"14.

Eine besondere Herausforderung ist das durch die Batterie ins Fahrzeug eingebrachte Zusatzgewicht. Hierdurch ergibt sich ein Konflikt zu der bestehenden Kundenerwartung nach einer hohen Reichweite.\r\nDurch den umfangreichen Einsatz von höchstfesten Stählen in dünnen Blechdicken im Karosseriebau soll die Reduzierung des Gesamtfahrzeuggewichts vorangetrieben werden. Vor allem im stahlintensiven Leichtbau ist das Widerstandspunktschweißen aufgrund des hohen Automatisierungsgrads, der Prozesssicherheit und der damit verbundenen Wirtschaftlichkeit das dominierende Fügeverfahren. Um Begrenzungen des Bauraums der Karosserie zu begegnen und um den Materialeinsatz im Leichtbau möglichst effizient zu gestalten, werden mehrschnittige Punktschweißverbindungen eingesetzt. Hieraus ergeben sich neue Herausforderungen für die Vorhersage des Trag- und Versagensverhaltens unter Crashbelastung.\r\nDieser Beitrag stellt eine systematische Charakterisierung von 3-Blechverbindungen zur Auffindung von formelmäßigen, empirischen Zusammenhängen zwischen der Festigkeit der Verbindung und den Einflussgrößen vor.\r\nNach der Identifikation geeigneter Einflussgrößen, wie zum Beispiel Blechfestigkeit, Blechanordnung, Blechdickenkombination sowie Belastungsart und Lasteinleitung, auf das Trag- und Versagensverhalten, werden numerische Simulationen durchgeführt, um Ursachen für auftretende Phänomene aus den experimentellen Ergebnissen aufzuklären. Weiterhin wird untersucht, inwieweit das Verhalten von 2-Blechverbindungen auf \r\n3-Blechverbindungen übertragbar ist. Die gefundenen Zusammenhänge sollen schnelle und kostengünstige Abschätzungen über die Festigkeit von 3-Blechbverbindungen ermöglichen. Darüber hinaus werden Ersatzmodelle für die Crashsimulation von \r\n3-Blechverbindungen entwickelt, die recheneffizient für die Sicherheitsbewertung von großen, geschweißten Bauteilen eingesetzt werden können. Dabei sollen insbesondere die Einflüsse des Lastangriffs an jeweils einer oder beiden Fügebenen auf die Festigkeit und Energieabsorption unter verschiedenen Belastungen wie Zug, Scherung sowie Biegung abbildbar sein.

The quantitative description of the material behavior under dynamic loading is of major importance for the evaluation of crash safety. This is carried out using numerical methods and requires characteristic values for the materials used. For the standardized determination of dynamic characteristic values in sheet metal materials, tensile tests performed according to the guideline from [1]. A particular challenge in dynamic tensile tests is the force measurement during the test. For this purpose, strain gauges are attached on each specimen, wired to the measuring equipment and calibrated. This is a common way to determine a force signal that is as low in vibration and as free of bending moments as possible. The preparation effort for the used strain gauges are enormous. For these reasons, an optical method to determine the force by strain measurement using DIC is presented. The experiments are carried out on a high speed tensile testing system. In combioantion with a 3D DIC high speed system for optical strain measurement. The elastic deformation of the specimen in the dynamometric section is measured using strain gauges and the optical method. The measured signals are then compared to validate the presented method. The investigations are conducted using the dual phase steel material HCT590X and the aluminum material EN AW-6014 T4.

One particular challenge is the additional weight added to the vehicle by the battery, which stands in direct contrast to the existing customer expectation of a high driving range. The reduction of the total vehicle weight is driven by the extensive use of ultra-high-strength steels in thin sheet thicknesses in car body construction. Resistance spot welding is the dominant joining process in steel-intensive lightweight construction due to its high degree of automation, process reliability and the associated economic efficiency.\r\nIn order to comply limitations of the space in the vehicle body and to ensure the most efficient use of materials in lightweight construction, joints are used that connect several sheets with a single spot weld. This leads to new challenges for the prediction of the load-bearing capacity and failure behaviour under crash loading.  \r\nThis paper presents a systematic characterisation of 3 sheet steel joints in order to find formulary, empirical relationships between the load-bearing capacity of the joint and the affecting parameters.\r\nNumerical simulations are carried out in order to clarify the causes of occurring phenomena in experiments. For this purpose, influencing variables such as joint strength, joint arrangement, sheet thickness, sheet strength, load type and load case on the load bearing capacity and failure behaviour are identified.\r\nFurthermore, the extent to which the behaviour of 2-sheet joints can be transferred to 3-sheet joints is investigated. A formulary correlation enables a quick and inexpensive estimates of the load-bearing capacity of 3-sheet metal connections. These models can be used for a computer-efficient simulation of components with three layered spot welded joints.","lang":"eng"}],"user_id":"7728","_id":"35947","language":[{"iso":"eng"}]},{"date_created":"2022-05-30T08:50:00Z","author":[{"last_name":"Olfert","full_name":"Olfert, Viktoria","id":"5974","first_name":"Viktoria"},{"full_name":"Meschut, Gerson","id":"32056","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson"},{"last_name":"Hein","id":"7728","full_name":"Hein, David","first_name":"David"},{"first_name":"Philip","last_name":"Rochel","full_name":"Rochel, Philip"},{"full_name":"Sommer, Silke","last_name":"Sommer","first_name":"Silke"}],"date_updated":"2022-05-30T08:52:02Z","conference":{"name":"11.
