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."}],"issue":"2","publication":"Nanomanufacturing and Metrology","doi":"10.1007/s41871-022-00143-9","language":[{"iso":"eng"}],"intvolume":" 5","publication_status":"published","date_updated":"2023-01-02T11:10:08Z","author":[{"full_name":"Schaude, Janik","first_name":"Janik","last_name":"Schaude"},{"last_name":"Hausotte","first_name":"Tino","full_name":"Hausotte, Tino"}],"publication_identifier":{"issn":["2520-811X","2520-8128"]},"year":"2022","title":"Atomic Force Microscope with an Adjustable Probe Direction and Integrated Sensing and Actuation","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285 – C05: TRR 285 - Subproject C05","_id":"149"}],"citation":{"mla":"Schaude, Janik, and Tino Hausotte. “Atomic Force Microscope with an Adjustable Probe Direction and Integrated Sensing and Actuation.” Nanomanufacturing and Metrology, vol. 5, no. 2, Springer Science and Business Media LLC, 2022, pp. 139–48, doi:10.1007/s41871-022-00143-9.","bibtex":"@article{Schaude_Hausotte_2022, title={Atomic Force Microscope with an Adjustable Probe Direction and Integrated Sensing and Actuation}, volume={5}, DOI={10.1007/s41871-022-00143-9}, number={2}, journal={Nanomanufacturing and Metrology}, publisher={Springer Science and Business Media LLC}, author={Schaude, Janik and Hausotte, Tino}, year={2022}, pages={139–148} }","ama":"Schaude J, Hausotte 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."}],"publication":"Key Engineering Materials","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"type":"conference","department":[{"_id":"630"}],"date_created":"2022-12-07T16:38:44Z"},{"project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B05: TRR 285 - Subproject B05","_id":"144"}],"citation":{"ieee":"C.

Since the application of such joining techniques often base on the ability to reach similar or even better joint loading capacities compared to established joining processes (e.g., spot welding), few contributions investigated the systematic improvement of clinch joint characteristics. In this regard, the use of data-driven methods in combination with optimization algorithms showed already high potentials for the analysis of individual joints and the definition of optimal tool configurations. However, the often missing consideration of uncertainties, such as varying material properties, and the related calculation of their impact on clinch joint properties can lead to poor estimation results and thus to a decreased reliability of the entire joint connection. This can cause major challenges, especially for the design and dimensioning of safety-relevant components, such as in car bodies. Motivated by this, the presented contribution introduces a novel method for the robust estimation of clinch joint characteristics including uncertainties of varying and versatile process chains in mechanical joining. Therefore, the utilization of Gaussian process regression models is demonstrated and evaluated regarding the ability to achieve sufficient prediction qualities."}],"publication":"The International Journal of Advanced Manufacturing Technology","keyword":["Industrial and Manufacturing Engineering","Computer Science Applications","Mechanical Engineering","Software","Control and Systems Engineering"],"type":"journal_article","department":[{"_id":"630"}],"date_created":"2022-12-14T12:24:29Z","publication_status":"published","date_updated":"2023-01-02T11:14:26Z","title":"Robust estimation of clinch joint characteristics based on data-driven methods","year":"2022","publication_identifier":{"issn":["0268-3768","1433-3015"]},"author":[{"full_name":"Zirngibl, Christoph","last_name":"Zirngibl","first_name":"Christoph"},{"first_name":"Benjamin","last_name":"Schleich","full_name":"Schleich, Benjamin"},{"first_name":"Sandro","last_name":"Wartzack","full_name":"Wartzack, Sandro"}],"doi":"10.1007/s00170-022-10441-7","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s00170-022-10441-7","open_access":"1"}],"language":[{"iso":"eng"}]},{"author":[{"first_name":"Sven","last_name":"Harzheim","full_name":"Harzheim, Sven"},{"full_name":"Hofmann, Martin","last_name":"Hofmann","first_name":"Martin"},{"full_name":"Wallmersperger, Thomas","last_name":"Wallmersperger","first_name":"Thomas"}],"publication_identifier":{"issn":["1537-6494","1537-6532"]},"year":"2022","title":"Numerical fatigue life prediction of corroded and non-corroded clinched joints","publication_status":"published","date_updated":"2023-01-02T11:10:49Z","language":[{"iso":"eng"}],"doi":"10.1080/15376494.2022.2140233","publication":"Mechanics of Advanced Materials and Structures","abstract":[{"lang":"eng","text":"Mechanical clinching is used to create lightweight hybrid structures.

Clinching is a conventional cold forming process in which two or more sheets can be joined without auxiliary parts. A pre-forming of the parts to be joined, which is introduced by previous manufacturing steps, has an influence on the joining result. When considering the suitability for joining with regard to the formability of the materials, the influence of the preforming steps must be taken into account. The influences of strain hardening and sheet thickness on the joining properties must be investigated. In this context, a Finite Element Method (FEM) based metamodel analysis of the clinching process was carried out in [1] to investigate the robustness of the clinching process with respect to the different material pre-strains. In [2], the method was extended to the load bearing simulation.Procedure. The metamodel from preliminary work based on various FE models, which predicts the load-bearing capacity of a clinched joint influenced by pre-straining, is compared here with experimental data and the accuracy of the metamodel prediction is discussed. For this purpose an experimental procedure was further develop which allows the preforming of metal sheets from which joining specimens can be separated with a certain degree of unidirectional deformation. In the study, the procedure for preparing the joint specimens and the results of the loading tests are presented. Different possible relevant pre-strain combinations are investigated and compared with the simulation results, to validate the FE models and choose suitable metamodel.","lang":"eng"}],"publication":"Key Engineering Materials","department":[{"_id":"157"}],"type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"date_created":"2022-07-25T11:16:15Z","intvolume":" 926","date_updated":"2023-01-12T14:22:52Z","publication_status":"published","publication_identifier":{"issn":["1662-9795"]},"author":[{"id":"34782","full_name":"Bielak, Christian Roman","last_name":"Bielak","first_name":"Christian Roman"},{"last_name":"Böhnke","first_name":"Max","full_name":"Böhnke, Max","id":"45779"},{"first_name":"Mathias","last_name":"Bobbert","full_name":"Bobbert, Mathias","id":"7850"},{"id":"32056","first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","full_name":"Meschut, Gerson"}],"title":"Experimental and Numerical Investigation on Manufacturing-Induced Pre-Strain on the Load-Bearing Capacity of Clinched Joints","year":"2022","doi":"10.4028/p-5d009y","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"ieee":"C.

For example, in the automotive sector, cast components are used at the junctions of the body and joined with different types of sheet metal and extruded profiles. To be able to join structures consisting of different materials, alternative joining technologies have emerged in recent years. This includes clinching, which allows assembling of two or more thin sheet metal and casting parts by solely cold forming the material. Clinching the brittle and usually less ductile cast aluminium alloys remains a challenge because the brittle character of the cast aluminium alloys can cause cracks during the forming of the clinched joint. In this study, the influence of the heat treatment time of an aluminium casting alloy AlSi9 on the joinability in the clinching process is investigated. Specific heat treatment of the naturally hard AlSi9 leads to a modification of the eutectic microstructure, which can increase ductility. Based on this, it will be examined if specific clinching die geometries can be used, which achieve an optimized geometrical formation of the clinched joint. The load-bearing capacities of the clinched joints are determined and compared by shear tensile and head tensile tests. Furthermore, the joints are examined microscopically to investigate the influence of the heat treatment on the failure behaviour during the load-bearing tests as well as crack initiation within the joining process.

In spaceframe technology, both sheet metal and continuous cast are joined to castings at the nodal points of the chassis. Since resistance spot welding is not an option when different materials are joined, research is focusing on mechanical joining methods for multi-material designs. To reduce weight and achieve the required strength, hardenable cast aluminium alloys of the AlSi-system are widely used. Thus, 85–90% of aluminium castings in the automotive industry are comprised of the AlSi-system. Due to the limited weldability, mechanical joining is a suitable process. For this application, various optimisation strategies are required to produce a crack-free joint, as the brittle character of the AlSi alloy poses a challenge. Thus, adapted castings with appropriate ductility are needed. Hence, in this study, the age-hardenable cast aluminium alloy AlSi10Mg is investigated regarding the correlation of the different thicknesses, the microstructural characteristics as well as the resulting mechanical properties. A variation of the thicknesses leads to different solidification rates, which in turn affect the microstructure formation and are decisive for the mechanical properties of the casting as well as the joinability. For the investigation, plates with thicknesses from 2.0 to 4.0 mm, each differing by 0.5 mm, are produced via sand casting. Hence, the overall aim is to evaluate the joinability of AlSi10Mg and derive conclusions concerning the microstructure and mechanical properties.","lang":"eng"}],"publication":"Production Engineering","keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering"],"type":"journal_article","department":[{"_id":"43"},{"_id":"158"},{"_id":"321"},{"_id":"630"}],"date_created":"2022-01-24T08:27:48Z","status":"public","user_id":"32340","_id":"29505","publisher":"Springer Science and Business Media LLC","quality_controlled":"1","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 – A02: TRR 285 - Subproject A02","_id":"136"}],"citation":{"apa":"Neuser, M., Grydin, O., Frolov, Y., & Schaper, M.

LME manifested itself as high-penetration cracks around the circumference of the spot welds for welding currents closely below the expulsion limit. At the same time, the observed tendency for LME cracking showed no direct correlation with the overall heat input of the investigated welding processes. To identify a reliable indicator of the tendency for LME cracking, the local strain rate at the origin of the observed cracks was analyzed over the course of the welding process via finite element simulation.

An efficient design and dimensioning of clinched joints requires a holistic understanding of the material, the joining process and the resulting properties of the joint. In this paper, the process chain for clinching metal sheets is described and experimental techniques are proposed to analyze the process-microstructure-property relationships from the sheet metal to the joined structure. At the example of clinching aluminum EN AW 6014, characterization methods are applied and discussed for the following characteristics: the mechanical properties of the sheet materials, the tribological behavior in the joining system, the joining process and the resulting material structure, the load-bearing behavior of the joint, the damage and degradation as well as the service life and crack growth behavior. The compilation of the characterization methods gives an overview on the advantages and weaknesses of the methods and the multiple interactions of material, process and properties during clinching. In addition, the results of the analyses on EN AW 6014 can be applied for parameterization and validation of simulations.","lang":"eng"}],"publication":"Journal of Advanced Joining Processes","doi":"10.1016/j.jajp.2022.100108","article_number":"100108","language":[{"iso":"eng"}],"date_updated":"2024-03-20T11:54:33Z","publication_status":"published","intvolume":" 5","year":"2022","title":"Clinching of Aluminum Materials – Methods for the Continuous Characterization of Process, Microstructure and Properties","author":[{"full_name":"Kupfer, Robert","first_name":"Robert","last_name":"Kupfer"},{"full_name":"Köhler, Daniel","last_name":"Köhler","first_name":"Daniel"},{"last_name":"Römisch","first_name":"David","full_name":"Römisch, David"},{"first_name":"Simon","last_name":"Wituschek","full_name":"Wituschek, Simon"},{"first_name":"Lars","last_name":"Ewenz","full_name":"Ewenz, Lars"},{"full_name":"Kalich, Jan","first_name":"Jan","last_name":"Kalich"},{"id":"45673","full_name":"Weiß, Deborah","last_name":"Weiß","first_name":"Deborah"},{"full_name":"Sadeghian, Behdad","last_name":"Sadeghian","first_name":"Behdad"},{"first_name":"Matthias","last_name":"Busch","full_name":"Busch, Matthias"},{"full_name":"Krüger, Jan Tobias","last_name":"Krüger","first_name":"Jan Tobias","orcid":"0000-0002-0827-9654","id":"44307"},{"id":"32340","full_name":"Neuser, Moritz","first_name":"Moritz","last_name":"Neuser"},{"last_name":"Grydin","first_name":"Olexandr","full_name":"Grydin, Olexandr","id":"43822"},{"last_name":"Böhnke","first_name":"Max","full_name":"Böhnke, Max","id":"45779"},{"id":"34782","first_name":"Christian Roman","last_name":"Bielak","full_name":"Bielak, Christian Roman"},{"full_name":"Troschitz, Juliane","first_name":"Juliane","last_name":"Troschitz"}],"publication_identifier":{"issn":["2666-3309"]},"quality_controlled":"1","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"148","name":"TRR 285 – C04: TRR 285 - Subproject C04"},{"name":"TRR 285 – C02: TRR 285 - Subproject C02","_id":"146"},{"_id":"145","name":"TRR 285 – C01: TRR 285 - Subproject C01"},{"_id":"132","name":"TRR 285 - B: TRR 285 - Project Area B"},{"name":"TRR 285 – B02: TRR 285 - Subproject B02","_id":"141"},{"_id":"138","name":"TRR 285 – A04: TRR 285 - Subproject A04"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"},{"name":"TRR 285 – A02: TRR 285 - Subproject A02","_id":"136"},{"_id":"149","name":"TRR 285 – C05: TRR 285 - Subproject C05"},{"name":"TRR 285 – B04: TRR 285 - Subproject B04","_id":"143"}],"citation":{"short":"R.

Reactive intermediates are detected to understand the underlying chemistry by using a microreactor coupled to a synchrotron light source. Utilizing soft photoionization coupled with photoelectron‐photoion coincidence detection enables us to characterize exclusive intermediates isomer‐selectively. A reaction mechanism for the ferrocene decomposition is proposed, which proceeds as a two‐step process. Initially, the molecule decomposes in a homogeneous surface reaction at temperatures <900 K, leading to products such as cyclopentadiene and cyclopentadienyl radicals that are immediately released to the gas‐phase. At higher temperatures, ferrocene rapidly decomposes in the gas‐phase, losing two cyclopentadienyl radicals in conjunction with iron. The addition of hydrogen to the reaction mixture reduces the decomposition temperature, and changes the branching ratio of the products. This change is mainly attributed to the H‐addition of cyclopentadienyl radicals on the surface, which leads to a release of cyclopentadiene into the gas‐phase. On the surface, ligand fragments may also undergo a series of catalytic H‐losses leading most probably to a high carbon content in the film. Finally, Arrhenius parameters for both global reactions are presented."}],"extern":"1","date_created":"2024-03-27T17:47:25Z","type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials"],"department":[{"_id":"728"}],"status":"public","publisher":"Wiley","_id":"53083","user_id":"94562","volume":9,"citation":{"apa":"Grimm, S., Hemberger, P., Kasper, T., & Atakan, B.

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. Strain rates of up to 240 s-1 are investigated.","lang":"eng"}],"publication":"Key Engineering Materials","department":[{"_id":"157"},{"_id":"630"}],"keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"type":"journal_article","date_created":"2022-08-18T09:33:54Z","conference":{"location":"Braga, Portugal","name":"ESAFORM 2022"},"status":"public","volume":926,"user_id":"45779","_id":"33002","publisher":"Trans Tech Publications, Ltd.","page":"1564-1572","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"}],"quality_controlled":"1","citation":{"ieee":"M.
