In this\r\nrespect, the use of hybrid structures, made of dissimilar materials offers many advantages. However, such hybrid\r\nstructures often have undesirable side effects. For example, brittle intermetallic phases are formed when\r\naluminum and steel are welded. Clinching as a mechanical joining process does not produce such intermetallic\r\nphases since the connection is realized through form and force closure. In this process, a punch passes through\r\ntwo or more sheets and forms them into a permanent joint in a die. In the present work, the corrosion phenomena\r\nof an aluminum-steel clinched joint have been investigated by both experiments and numerical simulations in\r\norder to explain the superior fatigue behavior of pre-corroded joints. Therefore, the clinched joints have been\r\ncorroded by a three-week salt-spray test. In addition, the electric potential and the von Mises stress are calculated\r\nunder the assumption of a static loading. The results of both experiments and numerical simulations can explain\r\nthe improvement in the fatigue behavior of the corroded specimens. This phenomenon can be attributed to the\r\naccumulation of corrosion products in small gaps between the joined metal sheets."}],"publication":"Journal of Advanced Joining Processes","language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Mechanics of Materials","Engineering (miscellaneous)","Chemical Engineering (miscellaneous)"],"intvolume":"         6","citation":{"chicago":"Harzheim, Sven, Lars Ewenz, Martina Zimmermann, and Thomas Wallmersperger. “Corrosion Phenomena and Fatigue Behavior of Clinched Joints: Numerical and Experimental Investigations.” <i>Journal of Advanced Joining Processes</i> 6 (2022). <a href=\"https://doi.org/10.1016/j.jajp.2022.100130\">https://doi.org/10.1016/j.jajp.2022.100130</a>.","ieee":"S.

Clinch connections are applicable to difficult-to-join hybrid material combinations, such as steel and aluminum. Therefore, this technology is interesting for the application of AISI 304 components, as this material is widely used as a highly formable sheet material. A characteristic feature of AISI 304 is its metastability, i.e., the face-centered cubic (fcc) γ-austenite can transform into a significantly stronger body-centered cubic (bcc) α’-martensite under plastic deformation. This work investigates the effect of heat treatment—a process that involves the formation of an oxidation layer on the sheet surface—on the forming process during joining and the resulting mechanical properties of clinch joints made from AISI 304. For this purpose, different joints made from non-heat treated and heat-treated sheets were examined using classical metallography and advanced SEM techniques, accompanied by further investigations, such as hardness and feritscope measurements. The shear tensile strength was determined, and the fracture behavior of the samples was investigated. Clear influences of heat-treatment-induced surface roughness on the joint geometry and strength were observed.","lang":"eng"}],"publication":"Metals","language":[{"iso":"eng"}],"keyword":["General Materials Science","Metals and Alloys"],"citation":{"ieee":"A.

For this reason, new versatile joining processes are in demand for joining dissimilar materials. In this regard, pin joining with cold extruded pin structures is a relatively new, two-stage joining process for joining materials such as high-strength steel and aluminium as well as steel and fibre-reinforced plastic to multi-material systems, without the need for auxiliary elements. Due to the novelty of the process, there are currently only a few studies on the robustness of this joining process available. Thus, limited statements on the stability of the joining process considering uncertain process conditions, such as varying material properties or friction values, can be provided. Motivated by this, the presented work investigates the influence of different uncertain process parameters on the pin extrusion as well as on the joining process itself, carrying out a systematic robustness analysis. Therefore, the methodical approach covers the complete process chain of pin joining, including the load-bearing capacity of the joint by means of numerical simulation and data-driven methods. Thereby, a deeper understanding of the pin joining process is generated and the versatility of the novel joining process is increased. Additionally, the provision of manufacturing recommendations for the forming of pin joints leads to a significant decrease in the failure probability caused by ploughing or buckling effects."}],"status":"public","_id":"34249","project":[{"grant_number":"418701707","name":"TRR 285: TRR 285","_id":"130"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"name":"TRR 285 – B05: TRR 285 - Subproject B05","_id":"144"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285 – C01: TRR 285 - Subproject C01","_id":"145"}],"department":[{"_id":"630"}],"user_id":"14931","keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering","Mechanics of Materials"],"article_number":"122","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2504-4494"]},"publication_status":"published","issue":"5","year":"2022","intvolume":"         6","citation":{"ama":"Römisch D, Zirngibl C, Schleich B, Wartzack S, Merklein M.

The load behaviour of composite parts strongly depends on the resultant material structure. The prediction of this material structure is a challenging task and requires a deep knowledge of the material behaviour above melting temperature and the occurring complex forming phenomena. Through this knowledge, the optimisation of manufacturing parameters for a more efficient and reproducible process can be enabled and are in the focus of many investigations. In the present paper, a simplified pultrusion test rig is developed and presented to investigate the deformation behaviour of a thermoplastic semi-finished fiber product in a forming element. Therefore, different process parameters, like forming element temperature, pulling velocity as well as the forming element geometry, are varied. The deformation behaviour in the forming zone of the thermoplastic preimpregnated continuous glass fibre-reinforced material is investigated by computed tomography and the resultant pulling forces are measured. The results clearly show the correlation between the forming element temperature and the resulting forces due to a change in the viscosity of the thermoplastic matrix and the resulting fiber matrix interaction. In addition, the evaluation of the measurement data shows which forming forces are required to change the shape of the thermoplastic unidirectional material with a rectangular cross-section to a round one."}],"language":[{"iso":"eng"}],"keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering","Mechanics of Materials"],"publication_status":"published","publication_identifier":{"issn":["2504-4494"]},"citation":{"ieee":"A.

Nevertheless, the process of pin extrusion offers process limits regarding sheet thinning as a consequence of the punch penetration depth into the sheet. Thereby, cracks at the residual sheet thickness can occur during strength tests, resulting in a failure of the complete joint due to severe thinning. Therefore, measures have to be taken into account to reduce the thinning. One possibility is the application of orbital formed tailored blanks with a local material pre-distribution, which allows a higher sheet thickness in the desired area. Within this contribution, the novel approach of a process combination of orbital forming and pin extrusion is investigated. To reveal the potential of a local material pre-distribution, conventional specimens are compared with previously orbital formed components. Relevant parameters such as the residual sheet thickness, the pin height as well as the average hardness values are compared. The results show a significant positive influence of a local material pre-distribution on the residual sheet thickness as well as the resulting pin height. Furthermore, the strain hardening during orbital forming can be seen as an additional advantage. To conclude the results, the process limits of conventional pin extrusion can be expanded significantly by the application of specimens with a local material pre-distribution."}],"publication":"Journal of Manufacturing and Materials Processing","language":[{"iso":"eng"}],"keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering","Mechanics of Materials"],"year":"2022","issue":"6","title":"Pin Extrusion for Mechanical Joining from Orbital Formed Tailored Blanks with Local Material Pre-Distribution","date_created":"2022-12-06T18:56:24Z","publisher":"MDPI AG"},{"publication":"Polymers","abstract":[{"text":"The paper presents research regarding a thermally supported multi-material clinching process (hotclinching) for metal and thermoplastic composite (TPC) sheets: an experimental approach to investigate the flow pressing phenomena during joining.

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.

The AFM, which is operated in closed-loop intermittent contact mode, is based on two rotational axes that enable the adjustment of the probe direction to cover a complete hemisphere. The axes greatly enlarge the metrology frame of the measuring system by materials with a comparatively high coefficient of thermal expansion, which ultimately limits the achievable measurement uncertainty of the measuring system. Thus, to reduce the thermal sensitivity of the system, the redesign of the rotational kinematics is mandatory. However, in this article, some preliminary investigations on the application of a self-sensing cantilever with an integrated micro heater for its stimulation will be presented. In previous investigations, a piezoelectric actuator has been applied to stimulate the cantilever. However, the removal of the piezoelectric actuator, which is enabled by the application of a cantilever with an integrated micro heater, promises an essential simplification of the sensor holder. Thus, in the future it might be possible to use materials with a low coefficient of thermal expansion, which are often difficult to machine and therefore only allow for rather simple geometries. Furthermore, because of the creepage of piezoelectric actuators, their removal from the metrology frame might lead to improved metrological characteristics. As will be shown, there are no significant differences between the two modes of actuation. Therefore, the redesigned rotational system will be based on the cantilever with integrated sensing and actuation.","lang":"eng"}],"publication":"Nanomanufacturing and Metrology","doi":"10.1007/s41871-022-00143-9","volume":5,"author":[{"full_name":"Schaude, Janik","last_name":"Schaude","first_name":"Janik"},{"first_name":"Tino","full_name":"Hausotte, Tino","last_name":"Hausotte"}],"date_updated":"2023-01-02T11:10:08Z","intvolume":"         5","page":"139-148","citation":{"ama":"Schaude J, Hausotte T.

The demand for precise predictions increases with the desire of lightweight design in transportation due to environmental protection. Corrosion with its manifold of mechanisms often occurs together with the production of hydrogen by electrochemical reactions. Hydrogen embrittlement is one of the most feared damage mechanisms for metal constructions often leading to early and unexpected failure. Until now, predictions are mostly based on costly experiments. Hence, a rational predictive model based on the fundamentals of electrochemistry and damage mechanics has to be developed in order to reduce the costs. In this work, a first model approach based on classical continuum damage mechanics is presented to couple both, the damage induced by the mechanical stress and the hydrogen embrittlement. An elaborated two-scale model based on the selfconsistent theory is applied to describe the mechanical damage due to fatigue. The electrochemical kinetics are elucidated through the Langmuir adsorption isotherm and the diffusion equation to consider the impact of hydrogen embrittlement on the fatigue. The modeling of the mechanism of hydrogen embrittlement defines the progress of damage accumulation due to the electrochemistry. The durability results like the S-N diagram show the influence of hydrogen embrittlement by varying, e.g. the fatigue frequency or the stress ratio."}],"type":"book_chapter","publication":"Material Modeling and Structural Mechanics","doi":"10.1007/978-3-030-97675-0_9","title":"A Damage Model for Corrosion Fatigue Due to Hydrogen Embrittlement","date_created":"2022-12-05T20:53:13Z","author":[{"first_name":"Yuhao","last_name":"Shi","full_name":"Shi, Yuhao"},{"first_name":"Sven","last_name":"Harzheim","full_name":"Harzheim, Sven"},{"last_name":"Hofmann","full_name":"Hofmann, Martin","first_name":"Martin"},{"first_name":"Thomas","full_name":"Wallmersperger, Thomas","last_name":"Wallmersperger"}],"date_updated":"2023-01-02T11:10:26Z","publisher":"Springer International Publishing","citation":{"chicago":"Shi, Yuhao, Sven Harzheim, Martin Hofmann, and Thomas Wallmersperger. “A Damage Model for Corrosion Fatigue Due to Hydrogen Embrittlement.” In <i>Material Modeling and Structural Mechanics</i>.

Clinching is a well-known joining process for use in sheet metalworking. Currently, clinched joints are focusing on mechanically enhanced connections. Additionally, the demand for integrating electrical requirements to transmit electrical currents will be increased in the future. This integration is particularly important, for instance, in the e-mobility sector. It enables connecting battery cells with electrical joints of aluminum and copper. Systematic use of the process-specific advantages of this joining method opens up the possibility to find and create electrically optimized connections. The optimization for the transmission of electrical currents will be demonstrated for clinched joints by adapting the tool geometry and the clinched joint design. Based on a comparison of the electrical joint resistance, the limit use temperature is defined for the joining materials used based on the microstructural condition and the aging condition due to artificial aging. As a result of the investigations carried out, reliable current transmission at a constant conductor temperature of up to 120 °C can be achieved for clinched copper–copper joints.

The ALE method is more suited for this task since fibres are embedded without any mesh restrictions. Element types beam, solid, and discrete are considered for fibre modelling. It is shown that the beam formulation for ALE and 3D solid elements for the CFD method are the preferred options.","lang":"eng"}],"publication":"Materials","title":"Modelling and Simulation Strategies for Fluid–Structure-Interactions of Highly Viscous Thermoplastic Melt and Single Fibres—A Numerical Study","date_created":"2022-12-06T20:33:11Z","publisher":"MDPI AG","year":"2022","issue":"20"},{"date_created":"2022-12-06T20:47:16Z","publisher":"Springer Science and Business Media LLC","title":"Comparison of two mesh-moving techniques for finite element simulations of galvanic corrosion","issue":"11","year":"2022","language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Computational Mechanics"],"publication":"Acta Mechanica","abstract":[{"text":"Galvanic corrosion is a destructive process between dissimilar metals. The present paper presents a constructed numerical test case to simulate galvanic corrosion of two dissimilar metals. This test case is used to study the accuracy of different implementations to track the dissolving anode boundary. One technique is to numerically simulate a mesh displacement based on the prescribed displacement at the anode boundary. The second method is to adjust only the boundary elements. Re-meshing after a certain number of time steps is applied to both implementations. They produce similar results for an electrical and electrochemical field problem. This work shows that mesh smoothing does not result in higher accuracy when modeling a moving anode front. Adjusting only the boundary elements is sufficient when frequent re-meshing is used.","lang":"eng"}],"author":[{"first_name":"Sven","last_name":"Harzheim","full_name":"Harzheim, Sven"},{"first_name":"Martin","full_name":"Hofmann, Martin","last_name":"Hofmann"},{"first_name":"Thomas","last_name":"Wallmersperger","full_name":"Wallmersperger, Thomas"}],"volume":233,"date_updated":"2023-01-02T11:07:28Z","oa":"1","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s00707-022-03326-z","open_access":"1"}],"doi":"10.1007/s00707-022-03326-z","publication_status":"published","publication_identifier":{"issn":["0001-5970","1619-6937"]},"citation":{"ama":"Harzheim S, Hofmann M, Wallmersperger T.

To assure the clinch point’s quality, the force displacement curve during clinching or the bottom thickness are monitored. The most significant geometrical characteristics of the clinch point, neck thickness and undercut, are usually tested destructively by microsectioning. However, micrograph preparation goes ahead with a resetting of elastic deformations and crack-closing after unloading. To generate a comprehensive knowledge of the clinch point’s inner geometry under load, in-situ computed tomography (CT) and acoustic testing (TDA) can be combined. While the TDA is highly sensitive to the inner state of the clinch point, it could detect critical events like crack development during loading. If such events are indicated, the loading process is stopped and a stepped in-situ CT of the following crack and deformation development is performed. In this paper, the concept is applied to the process of clinching itself, providing a detailed three-dimensional insight in the development of the joining zone. A test set-up is used which allows a stepwise clinching of two aluminium sheets EN AW 6014. Furthermore, this set-up is positioned within a CT system. In order to minimize X-ray absorption, a beryllium cylinder is used within the set-up frame and clinching tools are made from Si3N4. The actuator and sensor necessary for the TDA are integrated in the set-up. In regular process steps, the clinching process is interrupted in order to perform a TDA and a CT scan. In order to enhance the visibility of the interface, a thin tin layer is positioned between the sheets prior clinching. It is shown, that the test-set up allows a monitoring of the dynamic behaviour of the specimen during clinching while the CT scans visualize the inner geometry and material flow non-destructively.","lang":"eng"}],"publication":"Key Engineering Materials","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"language":[{"iso":"eng"}]}]
