In general, the conditions in a deep-drawing process change due to changing tribology conditions, varying degrees of spring back, or scattering material properties in the sheet blanks, which affects the resulting pre-strain. Mechanical joining processes, especially clinching, are influenced by these process-related pre-strains. The final geometric shape of a clinched joint is affected to a significant level by the prior material deformation when joining with constant process parameters. That leads to a change in the stiffness and force transmission in the clinched joint due to the different geometric dimensions, such as interlock, neck thickness and bottom thickness, which directly affect the load bearing capacity. Here, the influence of the pre-straining in the deep drawing process on the force distribution in clinch points in an automotive assembly is investigated by finite-element models numerically. In further studies, the results are implemented in an optimization tool for designing clinched components. The methodology starts with a pre-straining of metal sheets. This step is followed by 2D rotationally symmetric forming simulations of the joining process. The resulting mesh of each forming simulation is rotated and 3D models are obtained. The clinched joint solid model with pre-strains is used further to determine the joint stiffnesses. With the simulation of the same test set-up with an equivalent point-connector model, the equivalent stiffness for each pre-strain combination is determined. Simulations are performed on a clinched component to assess the influence of pre-strain and sheet thinning on the clinched joint loadings by using the equivalent stiffnesses. The investigations clearly show that for the selected component, the loadings at the clinch points are dependent on the sheet thinning and the stiffnesses due to pre-strain. The magnitude of the influence varies depending on the quantity considered. For example, the shear force is more sensitive to the joint stiffness than to the sheet thinning.</jats:p>","lang":"eng"}],"keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2022","publisher":"Springer Science and Business Media LLC","date_created":"2022-02-22T12:52:09Z","title":"Numerical investigation of the clinched joint loadings considering the initial pre-strain in the joining area"},{"language":[{"iso":"eng"}],"user_id":"38177","department":[{"_id":"321"},{"_id":"149"},{"_id":"630"}],"project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"_id":"140","name":"TRR 285 – B01: TRR 285 - Subproject B01"}],"_id":"32813","status":"public","type":"journal_article","publication":"Key Engineering Materials","main_file_link":[{"open_access":"1","url":"https://www.scientific.net/KEM.926.1505"}],"conference":{"end_date":"29.04.2022","location":"Braga","name":"25th International Conference in Material Forming","start_date":"27.04.2022"},"doi":"  https://doi.org/10.4028/p-09md1c","title":"Influence of the Surrounding Sheet Geometry on a Clinched Joint","author":[{"first_name":"Sven","full_name":"Martin, Sven","id":"38177","last_name":"Martin"},{"full_name":"Kurtusic, Kristijan","last_name":"Kurtusic","first_name":"Kristijan"},{"last_name":"Tröster","id":"553","full_name":"Tröster, Thomas","first_name":"Thomas"}],"date_created":"2022-08-15T11:02:37Z","volume":927,"oa":"1","date_updated":"2023-04-28T11:58:23Z","citation":{"ama":"Martin S, Kurtusic K, Tröster T.

In this process, the core structure, which is provided with stiffening ribs and functional elements, is formed and joined to two metal belts in one single step. For experimental validation of the concept, the development of a prototypic molding tool and the manufacturing of hybrid beams including process parameters are described. Three-point bending tests and optical measurement technologies are used to characterize the failure behavior and mechanical properties of the produced hybrid beams. It was found that the innovative IMA process enables the manufacturing of hybrid components with high energy absorption and low weight in one step.

Therefore, artificial powder-spread-flaws are applied to the build jobs of tensile test specimens which are measured and analyzed regarding the elongation at break, strength and fracture position. For the characteristics of the flaws, the artificial grooves are varied in depth and width. Furthermore, the position of the flaw is changed form mid part to close to surface areas. It was shown, that several flaws are visible at the part surface, resulting in stress concentration and reduced performance. But there are as well parts with flaw-layers, which are not visible after the build process on the part. Those parts can have significantly reduced mechanical properties as well.","lang":"eng"}],"status":"public","_id":"33356","user_id":"464","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"keyword":["Selective Sasersintering","Process Monitoring","Powder Spread"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2022","place":"Austin, TX, USA","citation":{"apa":"Klippstein, S.

Recently, grafted perfect vortex beams (GPVBs) have attracted much attention due to their unique optical properties and potential applications. However, the current method to generate and manipulate GPVBs requires a complex and bulky optical system, hindering further investigation and limiting its practical applications. Here, a compact metasurface approach for generating and manipulating GPVBs in multiple channels is proposed and demonstrated, which eliminates the need for such a complex optical setup. A single metasurface is utilized to realize various superpositions of GPVBs with different combinations of topological charges in four channels, leading to asymmetric singularity distributions. The positions of singularities in the superimposed beam can be further modulated by introducing an initial phase difference in the metasurface design. The work demonstrates a compact metasurface platform that performs a sophisticated optical task that is very challenging with conventional optics, opening opportunities for the investigation and applications of GPVBs in a wide range of emerging application areas, such as singular optics and quantum science.","lang":"eng"}],"publisher":"Wiley","date_created":"2022-06-20T11:05:50Z","title":"Multichannel Superposition of Grafted Perfect Vortex Beams","quality_controlled":"1","issue":"30","year":"2022"},{"date_created":"2022-12-06T11:04:43Z","author":[{"last_name":"Kress","id":"13256","full_name":"Kress, Christian","first_name":"Christian"},{"first_name":"Tobias","last_name":"Schwabe","full_name":"Schwabe, Tobias","id":"39217"},{"full_name":"Rhee, Hanjo","last_name":"Rhee","first_name":"Hanjo"},{"first_name":"Sarp","last_name":"Kerman","full_name":"Kerman, Sarp"},{"first_name":"J.

This approach is based on the reduced density-matrix functional theory (RDMFT) formulation of the electronic structure problem. For that purpose, the density-matrix functional of the full system is decomposed into an indirectly coupled sum of density-matrix functionals for all its subsystems using the adaptive cluster approximation to RDMFT. The approximations involved in the decomposition and the adaptive cluster approximation itself can be systematically converged to the exact result. The solutions for the density-matrix functionals of the effective subsystems involves a constrained minimization over many-particle states that are approximated by parametrized trial states on the quantum computer similarly to the variational quantum eigensolver. The independence of the density-matrix functionals of the effective subsystems introduces a new level of parallelization and allows for the computational treatment of much larger molecules on a quantum computer with a given qubit count. In addition, for the proposed algorithm techniques are presented to reduce the qubit count, the number of quantum programs, as well as its depth. The evaluation of a density-matrix functional as the essential part of our approach is demonstrated for Hubbard-like systems on IBM quantum computers based on superconducting transmon qubits.","lang":"eng"}],"language":[{"iso":"eng"}]},{"citation":{"ieee":"V.

Their importance to various fields,\r\nincluding materials science, chemical sciences, computational chemistry and\r\ndevice physics, is underscored by the large fraction of available public\r\nsupercomputing resources devoted to these calculations. As we enter the\r\nexascale era, exciting new opportunities to increase simulation numbers, sizes,\r\nand accuracies present themselves. In order to realize these promises, the\r\ncommunity of electronic structure software developers will however first have\r\nto tackle a number of challenges pertaining to the efficient use of new\r\narchitectures that will rely heavily on massive parallelism and hardware\r\naccelerators. This roadmap provides a broad overview of the state-of-the-art in\r\nelectronic structure calculations and of the various new directions being\r\npursued by the community. It covers 14 electronic structure codes, presenting\r\ntheir current status, their development priorities over the next five years,\r\nand their plans towards tackling the challenges and leveraging the\r\nopportunities presented by the advent of exascale computing.","lang":"eng"}],"type":"preprint","publication":"arXiv:2209.12747","language":[{"iso":"eng"}],"user_id":"75963","department":[{"_id":"27"}],"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"external_id":{"arxiv":["2209.12747"]},"_id":"46275"},{"intvolume":"       111","citation":{"bibtex":"@article{Schade_Kenter_Elgabarty_Lass_Schütt_Lazzaro_Pabst_Mohr_Hutter_Kühne_et al._2022, title={Towards electronic structure-based ab-initio molecular dynamics simulations with hundreds of millions of atoms}, volume={111}, DOI={<a href=\"https://doi.org/10.1016/j.parco.2022.102920\">10.1016/j.parco.2022.102920</a>}, number={102920}, journal={Parallel Computing}, publisher={Elsevier BV}, author={Schade, Robert and Kenter, Tobias and Elgabarty, Hossam and Lass, Michael and Schütt, Ole and Lazzaro, Alfio and Pabst, Hans and Mohr, Stephan and Hutter, Jürg and Kühne, Thomas and et al.}, year={2022} }","short":"R.
