However, inherent to plastic forming is the nucleation and growth of defects, whose detrimental effects on the material behaviour can be described by continuum damage models and eventually lead to material failure. As the damage evolution strongly depends on the stress state, a stress-state-dependent model is utilised to correctly track the accumulation. To formulate and parameterise this model, besides classical experiments, so-called modified punch tests are also integrated herein to enhance the calibration of the failure model by capturing a larger range of stress states and metal-forming-specific loading conditions. Moreover, when highly ductile materials are considered, such as the dual-phase steel HCT590X and the aluminium alloy EN AW-6014 T4 investigated here, strong necking and localisation might occur prior to fracture. This can alter the stress state and affect the actual strain at failure. This influence is captured by coupling plasticity and damage to incorporate the damage-induced softening effect. Its relative importance is shown by conducting inverse parameter identifications to determine damage and failure parameters for both mentioned ductile metals based on up to 12 different experiments.","lang":"eng"}],"publication":"Journal of Manufacturing and Materials Processing","issue":"4","doi":"10.3390/jmmp8040157","article_number":"157","language":[{"iso":"eng"}],"date_updated":"2026-05-13T13:53:29Z","publication_status":"published","intvolume":"         8","title":"Material Parameter Identification for a Stress-State-Dependent Ductile Damage and Failure Model Applied to Clinch Joining","year":"2024","author":[{"full_name":"Friedlein, Johannes","first_name":"Johannes","last_name":"Friedlein"},{"full_name":"Böhnke, Max","last_name":"Böhnke","first_name":"Max","id":"45779"},{"id":"61977","full_name":"Schlichter, Malte Christian","first_name":"Malte Christian","last_name":"Schlichter"},{"id":"7850","full_name":"Bobbert, Mathias","last_name":"Bobbert","first_name":"Mathias"},{"last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson","full_name":"Meschut, Gerson","id":"32056"},{"last_name":"Mergheim","first_name":"Julia","full_name":"Mergheim, Julia"},{"full_name":"Steinmann, Paul","last_name":"Steinmann","first_name":"Paul"}],"publication_identifier":{"issn":["2504-4494"]},"quality_controlled":"1","project":[{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"mla":"Friedlein, Johannes, et al. “Material Parameter Identification for a Stress-State-Dependent Ductile Damage and Failure Model Applied to Clinch Joining.” <i>Journal of Manufacturing and Materials Processing</i>, vol. 8, no. 4, 157, MDPI AG, 2024, doi:<a href=\"https://doi.org/10.3390/jmmp8040157\">10.3390/jmmp8040157</a>.","bibtex":"@article{Friedlein_Böhnke_Schlichter_Bobbert_Meschut_Mergheim_Steinmann_2024, title={Material Parameter Identification for a Stress-State-Dependent Ductile Damage and Failure Model Applied to Clinch Joining}, volume={8}, DOI={<a href=\"https://doi.org/10.3390/jmmp8040157\">10.3390/jmmp8040157</a>}, number={4157}, journal={Journal of Manufacturing and Materials Processing}, publisher={MDPI AG}, author={Friedlein, Johannes and Böhnke, Max and Schlichter, Malte Christian and Bobbert, Mathias and Meschut, Gerson and Mergheim, Julia and Steinmann, Paul}, year={2024} }","ama":"Friedlein J, Böhnke M, Schlichter MC, et al.

In the numerical simulation of mechanical joining technologies such as clinching, the material modeling of the joining parts is of major importance. This includes modeling the damage and failure behavior of the materials in accordance with varying occurring stress states. This paper presents a calibration method of three different fracture models. The calibration of the models is done by use of experimental data from a modified punch test, tensile test and bulge test in order to map the occurring stress states from clinching processes and to precisely model the resulting failure behavior. Experimental investigations were carried out for an aluminum alloy  EN AW-6014 in temper T4 and compared with the simulative results generated in LS-DYNA. The comparison of force-displacement curves and failure initiation shows that the Hosford–Coulomb model predicts the failure behavior for the material used and the tests applied with the best accuracy. </jats:p>","lang":"eng"}],"quality_controlled":"1","date_created":"2023-04-13T07:42:53Z","department":[{"_id":"157"}],"type":"conference","author":[{"id":"45779","full_name":"Böhnke, Max","last_name":"Böhnke","first_name":"Max"},{"full_name":"Bielak, Christian Roman","first_name":"Christian Roman","last_name":"Bielak","id":"34782"},{"full_name":"Friedlein, Johannes","last_name":"Friedlein","first_name":"Johannes"},{"id":"7850","last_name":"Bobbert","first_name":"Mathias","full_name":"Bobbert, Mathias"},{"full_name":"Mergheim, Julia","last_name":"Mergheim","first_name":"Julia"},{"full_name":"Steinmann, Paul","first_name":"Paul","last_name":"Steinmann"},{"orcid":"0000-0002-2763-1246","first_name":"Gerson","last_name":"Meschut","full_name":"Meschut, Gerson","id":"32056"}],"publication_identifier":{"issn":["2474-395X"]},"title":"A calibration method for failure modeling in clinching process simulations","status":"public","year":"2023","publication_status":"published","date_updated":"2024-03-11T08:14:53Z","language":[{"iso":"eng"}],"_id":"43462","publisher":"Materials Research Forum LLC","user_id":"45779","doi":"10.21741/9781644902417-34"},{"publication_status":"published","date_updated":"2024-03-11T08:13:57Z","author":[{"last_name":"Friedlein","first_name":"Johannes","full_name":"Friedlein, Johannes"},{"last_name":"Bielak","first_name":"Christian Roman","full_name":"Bielak, Christian Roman","id":"34782"},{"id":"45779","last_name":"Böhnke","first_name":"Max","full_name":"Böhnke, Max"},{"first_name":"Mathias","last_name":"Bobbert","full_name":"Bobbert, Mathias","id":"7850"},{"full_name":"Mergheim, Julia","first_name":"Julia","last_name":"Mergheim"},{"first_name":"Paul","last_name":"Steinmann","full_name":"Steinmann, Paul"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson"}],"title":"Influence of plastic orthotropy on clinching of sheet metal","status":"public","year":"2023","user_id":"45779","doi":"10.21741/9781644902417-17 ","_id":"43463","publisher":"Materials Research Forum LLC","language":[{"iso":"eng"}],"project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"name":"TRR 285 – A05: TRR 285 - Subproject A05","_id":"139"},{"name":"TRR 285 – A01: TRR 285 - Subproject A01","_id":"135"}],"quality_controlled":"1","citation":{"chicago":"Friedlein, Johannes, Christian Roman Bielak, Max Böhnke, Mathias Bobbert, Julia Mergheim, Paul Steinmann, and Gerson Meschut. “Influence of Plastic Orthotropy on Clinching of Sheet Metal.” In <i>Materials Research Proceedings</i>.

For online monitoring of self-piercing riveting, envelope curves are often used to define a tolerance zone for the measured setting force. However, the measurement uncertainty is typically not considered and the force curve of a joint can be wrongly rated as non-conform due to measurement errors and noise. In this article, we present a method for dynamical online filtering and uncertainty determination for noisy force curves using two types of Bayesian filters. The methodology is based on a Bayesian probability framework using a priori information for the process curve and sensor noise. To investigate the general feasibility of the method, force measurements with different noise levels are simulated and processed. The conformity is further assessed taking the uncertainty of the filtered signal into account. The results show that the Bayes filter technique is principally able to reduce noise for well-known characteristics of the process curve and sensor noise. Advantages over common filtering techniques, especially for experimental conditions with less known characteristics, are still to be verified. The methodology could be used in future for closed-loop controls to adapt process parameters dynamically. </jats:p>"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://www.mrforum.com/wp-content/uploads/open_access/9781644902417/48.pdf"}],"doi":"10.21741/9781644902417-48","publication_identifier":{"issn":["2474-395X"]},"author":[{"full_name":"Butzhammer, Lorenz","first_name":"Lorenz","last_name":"Butzhammer"},{"id":"66459","first_name":"Fabian","last_name":"Kappe","full_name":"Kappe, Fabian"},{"full_name":"Meschut, Gerson","first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","id":"32056"},{"first_name":"Tino ","last_name":"Hausotte","full_name":"Hausotte, Tino "}],"year":"2023","title":"Dynamic conformity assessment for joining force monitoring using Bayes filters","publication_status":"published","date_updated":"2024-03-25T10:44:19Z","oa":"1","citation":{"short":"L.

For the reduction of moving masses and the resources consumed, lightweight construction technologies are part of modern production processes in vehicle manufacturing, for example in the form of multi-material systems. Challenging in the manufacture of multi-material systems especially in view of changing supply chains is the variety of materials and geometries that bring conventional joining processes to their limits. Therefore, new processes are required, which can react versatile to process and disturbance variables. A widely used industrial joining process is semi-tubular self-piercing riveting, which is however a rigid process. To increase the versatility, the two newly established processes multi-range self-piercing riveting and tumbling self-piercing riveting are combined and the capabilities for targeted material flow control are united. Therefore, an innovative two-stage process based on the combination is introduced in this paper. The rivet is set with the multi-range self-piercing riveting process with an overlap of the rivet head and then formed by a tumbling process. Further, a specific adaptation of the tumbling strategy is used to investigate the possibility of reducing cracks in the rivet head. Thereby, different tumbling strategies are used and similar geometric joint formations are achieved to compare the results. </jats:p>"}],"publication":"Materials Research Proceedings","department":[{"_id":"157"}],"type":"conference","date_created":"2024-03-25T10:21:01Z","date_updated":"2024-03-25T12:41:23Z","publication_status":"published","publication_identifier":{"issn":["2474-395X"]},"author":[{"last_name":"Wituschek","first_name":"Simon","full_name":"Wituschek, Simon"},{"id":"66459","full_name":"Kappe, Fabian","last_name":"Kappe","first_name":"Fabian"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","first_name":"Gerson","orcid":"0000-0002-2763-1246"},{"full_name":"Lechner, Michael","last_name":"Lechner","first_name":"Michael"}],"year":"2023","title":"Combination of versatile self-piercing riveting processes","doi":"10.21741/9781644902417-16","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.mrforum.com/wp-content/uploads/open_access/9781644902417/16.pdf?","open_access":"1"}]},{"user_id":"45673","doi":"10.48447/WP-2023-244","publisher":"Deutscher Verband für Materialforschung und -prüfung e.V.","_id":"51739","language":[{"iso":"ger"}],"publication_status":"published","date_updated":"2024-04-10T07:08:49Z","author":[{"full_name":"Weiß, Deborah","first_name":"Deborah","last_name":"Weiß","id":"45673"},{"id":"41322","first_name":"Tobias","last_name":"Duffe","full_name":"Duffe, Tobias"},{"id":"83727","first_name":"Moritz","last_name":"Buczek","full_name":"Buczek, Moritz"},{"id":"291","first_name":"Gunter","last_name":"Kullmer","full_name":"Kullmer, Gunter"},{"id":"4668","full_name":"Schramm, Britta","first_name":"Britta","last_name":"Schramm"}],"conference":{"name":"Werkstoffprüfung 2023: Werkstoffe und Bauteile auf dem Prüfstand - Tagung","start_date":"2023-11-23","location":"Berlin","end_date":"2023-11-24"},"year":"2023","title":"Bruchmechanische Untersuchung des Dualphasenstahls HCT590X unter Temperatureinfluss","status":"public","department":[{"_id":"143"},{"_id":"630"}],"type":"conference","date_created":"2024-02-22T09:54:40Z","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"name":"TRR 285 – B04: TRR 285 - Subproject B04","_id":"143"}],"citation":{"apa":"Weiß, D., Duffe, T., Buczek, M., Kullmer, G., &#38; Schramm, B.

The miniaturisation of components leads to new demands on measurement systems. One of these is the resolution. As a volumetric analysis method and method of non-destructive testing, industrial X-ray computed\r\ntomography (XCT) has the ability to measure geometrical features and their corresponding dimensions without destroying them and can therefore be used for quality assurance. However, the concept of resolution is not trivial for XCT and has not yet been finally clarified. In particular, the interface structural resolution, the detectability of two surfaces facing each other after surface segmentation, faces a lack of a test specimen, a corresponding\r\nmeasurand and a reliable method. Simulation-based XCT investigations of a method to determine this type of resolution are presented in this article using the geometry of a test specimen that contains several radially\r\narranged holes of the same size. The borehole diameters correspond to the distance between the holes to investigate the resolvability of surfaces and interfaces. The evaluation is based on mean and extreme values of grey value\r\nprofiles between the individual boreholes of the reconstructed volume. It is shown that the geometrical detectability of the test specimen surface and interface can be extended by a reasonable choice of the threshold value for\r\nsurface segmentation within a defined interval. With regard to the resolving capability, a distinction is made between assured detectability and possible detectability, as well as the threshold value used when using the ISO50\r\nthreshold for surface segmentation and measurement chain completion.

Increasing resource efficiency is a major challenge and affects almost every aspect of social and economic life. The mobility sector in particular is responsible for a large share of primary energy consumption and is increasingly in the focus of public interest. One possibility to adress these challenges is to reduce the vehicle weight by means of lightweight construction technologies such as multi-material systems. These assemblies consist of workpieces with different mechanical and geometrical properties, which poses a major challenge for joining technology. Mechanical joining processes such as semi-tubular self-piercing riveting are often used in the production of these assemblies, but due to their process characteristics, they are rigid and can only react to changing process variables to a limited extent. One way to increase the versatility of self-piercing riveting is to superimpose a tumbling kinematics on the punch. During tumbling, an angular offset of the punch axis to the tool axis is set and the contact area between punch and workpiece is reduced. In this work, investigations were carried out to determine how the tumbling strategy, consisting of the parameters tumbling angle, tumbling onset and tumbling kinematics, affects the material flow of the rivet element. For this purpose, experimental tests are conducted with the typical materials of conventional multi-material systems and the geometric joint formations are determined by means of macrographs. </jats:p>","lang":"eng"}],"citation":{"mla":"Wituschek, S., et al. “Versatile Self-Piercing Riveting with a Tumbling Superimposed Punch.” <i>Materials Research Proceedings</i>, Materials Research Forum LLC, 2023, doi:<a href=\"https://doi.org/10.21741/9781644902479-122\">10.21741/9781644902479-122</a>.","ama":"Wituschek S, Elbel L, Lechner M.

Force-displacement measurements and macrosections are commonly used methods to validate numerical models of clinching processes. However, these ex-situ methods often lead to springback of elastic deformations and crack-closing after unloading. In contrast, the in-situ computed tomography (CT) can provide three-dimensional images of the clinching point under loading conditions. So far, the quantity of elastic springback that causes measuring deviations between in- and ex-situ measurements is not determined. In this paper, a method is described to quantitatively compare the results of in-situ CT, ex-situ CT and CT scans of cut specimens, which are prepared for macrosectioning, among each other. The method is applied to a single-lap shear test of two clinched aluminum sheets. Here, the test is conducted to specific process steps, then the specimen is CT scanned in-situ (during loading) and ex-situ (after unloading). Subsequently, the specimens are cut for macrosectioning and CT scanned. Finally, the outer contours and the interfaces of cross section images are determined by digital image analysis and the deviations over the clinching point between ex- and in-situ methods are calculated. </jats:p>","lang":"eng"}],"citation":{"ama":"Köhler D, Kupfer R, Troschitz J, Gude M.

The models being compared include plasticity - gradient-damage, where the gradient-enhancement is applied on the local damage variable, and gradient-plasticity - damage with a gradient-enhanced plastic hardening variable. Thereby, gradient-plasticity proved to be able to simultaneously regularise plastic and ductile (plasticity-driven) damage localisation as confirmed by numerical localisation analyses. This appears to be especially advantageous for logarithmic strain space plasticity-damage, because of the observed plastic localisation even for the case of plasticity with hardening. Even though gradient-plasticity appears to be numerically more demanding, two numerical examples indicate a good robustness and mesh objectivity in the softening regime. Moreover, the internal length for plasticity is able to adjust the damage zone width, similarly to gradient-damage, however ensuring a priori that damage takes place exclusively inside the plastic zone."}],"language":[{"iso":"eng"}],"article_number":"104946","doi":"10.1016/j.euromechsol.2023.104946","author":[{"last_name":"Friedlein","first_name":"Johannes","full_name":"Friedlein, Johannes"},{"last_name":"Mergheim","first_name":"Julia","full_name":"Mergheim, Julia"},{"full_name":"Steinmann, Paul","last_name":"Steinmann","first_name":"Paul"}],"publication_identifier":{"issn":["0997-7538"]},"year":"2023","title":"Efficient gradient enhancements for plasticity with ductile damage in the logarithmic strain space","intvolume":"        99","article_type":"original","date_updated":"2026-02-24T14:37:05Z","publication_status":"published","citation":{"bibtex":"@article{Friedlein_Mergheim_Steinmann_2023, title={Efficient gradient enhancements for plasticity with ductile damage in the logarithmic strain space}, volume={99}, DOI={<a href=\"https://doi.org/10.1016/j.euromechsol.2023.104946\">10.1016/j.euromechsol.2023.104946</a>}, number={104946}, journal={European Journal of Mechanics - A/Solids}, publisher={Elsevier BV}, author={Friedlein, Johannes and Mergheim, Julia and Steinmann, Paul}, year={2023} }","short":"J.
