The stacking sequence of the unidirectional plies forming a CFRP laminate, and their thicknesses, primarily determine the mechanical performance. However, during manufacturing, defects, e.g., pores and residual stresses, are induced, both affecting the mechanical properties. The objective of the present work is to accurately measure residual stresses in CFRPs as well as to investigate the effects of stacking sequence, overall laminate thickness, and the presence of pores on the residual stress state. Residual stresses were measured through the incremental hole-drilling method (HDM). Adequate procedures have been applied to evaluate the residual stresses for orthotropic materials, including calculating the calibration coefficients through finite element analysis (FEA) based on stacking sequence, laminate thickness and mechanical properties. Using optical microscopy (OM) and computed tomography (CT), profound insights into the cross-sectional and three-dimensional microstructure, e.g., location and shape of process-induced pores, were obtained. This microstructural information allowed for a comprehensive understanding of the experimentally determined strain and stress results, particularly at the transition zone between the individual plies. The effect of pores on residual stresses was investigated by considering pores to calculate the calibration coefficients at a depth of 0.06 mm to 0.12 mm in the model and utilizing these results for residual stress evaluation. A maximum difference of 46% in stress between defect-free and porous material sample conditions was observed at a hole depth of 0.65 mm. The significance of employing correctly calculated coefficients for the residual stress evaluation is highlighted by mechanical validation tests.</jats:p>","lang":"eng"}],"article_number":"138","language":[{"iso":"eng"}],"doi":"10.3390/jcs6050138","year":"2022","title":"Experimental Analysis of Residual Stresses in CFRPs through Hole-Drilling Method: The Role of Stacking Sequence, Thickness, and Defects","author":[{"last_name":"Wu","first_name":"Tao","full_name":"Wu, Tao"},{"last_name":"Kruse","first_name":"Roland","full_name":"Kruse, Roland"},{"id":"72722","full_name":"Tinkloh, Steffen Rainer","last_name":"Tinkloh","first_name":"Steffen Rainer"},{"id":"553","first_name":"Thomas","last_name":"Tröster","full_name":"Tröster, Thomas"},{"full_name":"Zinn, Wolfgang","first_name":"Wolfgang","last_name":"Zinn"},{"full_name":"Lauhoff, Christian","first_name":"Christian","last_name":"Lauhoff"},{"full_name":"Niendorf, Thomas","last_name":"Niendorf","first_name":"Thomas"}],"publication_identifier":{"issn":["2504-477X"]},"publication_status":"published","date_updated":"2023-04-28T11:31:42Z","intvolume":"         6","citation":{"mla":"Wu, Tao, et al. “Experimental Analysis of Residual Stresses in CFRPs through Hole-Drilling Method: The Role of Stacking Sequence, Thickness, and Defects.” <i>Journal of Composites Science</i>, vol. 6, no. 5, 138, MDPI AG, 2022, doi:<a href=\"https://doi.org/10.3390/jcs6050138\">10.3390/jcs6050138</a>.","ama":"Wu T, Kruse R, Tinkloh SR, et al.

In order to predict relevant properties of clinched joints and to ensure the reliability of the process, it is numerically simulated during the product development process. The prediction accuracy of the simulated process depends on the implemented friction model. Therefore, a new method for determining friction coefficients in sheet metal materials was developed and tested. The aim of this study is the numerical investigation of this experimental method by means of FE simulation. The experimental setup is modelled in a 3D numerical simulation taking into account the process parameters varying in the experiment, such as geometric properties, contact pressure and contact velocity. Furthermore, the contact description of the model is calibrated via the experimentally determined friction coefficients according to clinch-relevant parameter space. It is shown that the assumptions made in the determination of the experimental data in preliminary work are valid. In addition, it is investigated to what extent the standard Coulomb friction model in the FEM can reproduce the results of the experimental method. </jats:p>"}],"publication":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","user_id":"34782","publisher":"SAGE Publications","_id":"30962","status":"public","project":[{"name":"TRR 285: TRR 285","_id":"130","grant_number":"418701707"},{"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":"C.

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>"}],"date_created":"2022-02-22T12:52:09Z","department":[{"_id":"321"},{"_id":"149"},{"_id":"630"},{"_id":"157"}],"keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering"],"type":"journal_article"},{"citation":{"chicago":"Tittmann, Karsten , Ilja  Koch, Serkan Çavdar, Maik  Gude, and Gerson Meschut. “Service Strength Analysis Method for Adhesively Bonded Hybrid Structures under Multiaxial Loading.” In <i>Proceedings of the 20th European Conference on Composite Materials</i>, edited by Ecole Polytechnique Fédérale de Lausanne (EPFL), 2:730–39, 2022.","short":"K.

Due to plastic deformation of metastable austenitic steel, phase transformation from γ-austenite into α’-martensite occurs. This is initiated by the formation of shear bands as product of the external stresses. By means of coupled microscopic and micromagnetic investigations, a characterization of the microstructure was carried out. In particular, this study shows the distribution of the strain-induced α’-martensite and its influence on material properties like hardness at different depths. The microstructural analyses by means of electron backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite (ca. 23 %) close to the outer specimen surface, where the plastic deformation and the direct contact with the forming tool take place. In the middle area (ca. 1.5 mm depth from the outer surface), the portion of transformed α’-martensite drops to 7 % and in the inner surface to 2 %. These results are well correlated with microhardness and micromagnetic measurements at different depths. EBSD and atomic force microscopy (AFM) were used to make a detailed characterization of the topography and degree of deformation of the shear bands. Likewise, the mechanisms of nucleation of α’-martensite were discussed. This research contributes to the development of micromagnetic sensors to monitor the evolution of properties during flow forming. This makes them more suitable for closed-loop property control, which offers possibilities for an application-oriented and more efficient production.</jats:p>"}],"publication":"Practical Metallography","issue":"11","type":"journal_article","keyword":["Metals and Alloys","Mechanics of Materials","Condensed Matter Physics","Electronic","Optical and Magnetic Materials"],"department":[{"_id":"156"},{"_id":"153"},{"_id":"241"}],"date_created":"2022-11-04T08:29:21Z","date_updated":"2023-05-02T08:19:27Z","publication_status":"published","intvolume":"        59","year":"2022","title":"Coupled microscopic and micromagnetic depth-specific analysis of plastic deformation and phase transformation of metastable austenitic steel AISI 304L by flow forming","publication_identifier":{"issn":["2195-8599","0032-678X"]},"author":[{"full_name":"Rozo Vasquez, Julian","last_name":"Rozo Vasquez","first_name":"Julian"},{"first_name":"Hanigah","last_name":"Kanagarajah","full_name":"Kanagarajah, Hanigah"},{"full_name":"Arian, Bahman","last_name":"Arian","first_name":"Bahman","id":"36287"},{"full_name":"Kersting, Lukas","last_name":"Kersting","first_name":"Lukas"},{"full_name":"Homberg, Werner","last_name":"Homberg","first_name":"Werner","id":"233"},{"last_name":"Trächtler","first_name":"Ansgar","full_name":"Trächtler, Ansgar","id":"552"},{"last_name":"Walther","first_name":"Frank","full_name":"Walther, Frank"}],"doi":"10.1515/pm-2022-0064","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"short":"J.

Especially with small batch size, the incremental flow forming processes can be advantageous. The production of parts with complex geometry and locally graded material properties currently depicts a great challenge in the flow forming process. At this point, the usage of closed-loop control for the shape and properties could be a feasible new solution. The overall aim in this project is to establish an intelligent closed-loop control system for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces in a flow forming process. To reach this goal, a novel sensor concept for online measurements of the wall thickness reduction and the martensite content during forming process is proposed. It includes the setup of a modified flow forming machine and the integration of the sensor system in the machine control. Additionally, a simulation model for the flow forming process is presented which describes the forming process with regard to the plastic workpiece deformation, the induced α’-martensite fraction, and the sensor behavior. This model was used for designing a closed-loop process control of the wall thickness reduction that was subsequently realized at the real plant including online measured feedback from the sensor system.</jats:p>"}]},{"date_updated":"2023-05-02T08:20:04Z","conference":{"start_date":"2022-09-27","name":"ICBM 14, 14th International Conference on Barkhausen Noise and Micromagnetic Testing","location":"Stockholm","end_date":"2022-09-30"},"author":[{"last_name":"Rozo Vasquez","first_name":"Julian","full_name":"Rozo Vasquez, Julian"},{"full_name":"Walther, Frank","last_name":"Walther","first_name":"Frank"},{"first_name":"Bahman","last_name":"Arian","full_name":"Arian, Bahman","id":"36287"},{"last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner","id":"233"},{"full_name":"Kersting, Lukas","first_name":"Lukas","last_name":"Kersting"},{"first_name":"Ansgar","last_name":"Trächtler","full_name":"Trächtler, Ansgar"}],"year":"2022","status":"public","title":"Soft sensor concept for micromagnetic depth-specific analysis of phase transformation during flow forming of AISI 304L steel.","user_id":"36287","language":[{"iso":"eng"}],"_id":"36563","quality_controlled":"1","citation":{"ama":"Rozo Vasquez J, Walther F, Arian B, Homberg W, Kersting L, Trächtler A.

OTF Computing aims to eradicate the dependency on the requirement engineers for the software development process. However, there is no existing bidirectional chatbot solution that analyses user software requirements and provides viable suggestions to the user regarding their service. Previously, CORDULA chatbot was developed to analyze the software requirements but cannot keep the conversation’s context. The Rasa framework is integrated with the knowledge base to solve the issue, the knowledge base provides domain-specific knowledge to the chatbot. The software description is passed through the natural language understanding process to give consciousness to the chatbot. This process involves various machine learning models, including app family classification, to correctly identify the domain for user OTF service. The statistical models like naïve Bayes, kNN and SVM are compared with transformer models for this classification task. Furthermore, the entities (functional requirements) are also separated from the user description.\r\nThe chatbot provides the suggestion of requirements from the preliminary service template with the support of the knowledge base. Furthermore, the generated response is compared with the state-of-the-art DialoGPT transformer model and ChatterBot conversational library. These models are trained over the software development related conversational dataset. All the responses are ranked using the DialoRPT model, and the BLEU score to evaluates the models’ responses. Moreover, the chatbot mod- els are tested with human participants, they used and scored the chatbot responses based on effectiveness, efficiency and satisfaction.

This paper presents an innovative IMA process concept for the manufacturing of bending loaded hybrid components consisting of two outer metal belts and an inner core structure made of glass mat reinforced thermoplastic (GMT). 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. The mass-specific energy absorption is increased by 693 % compared to pure GMT beams.</jats:p>"}],"publication":"Key Engineering Materials"}]
