For a holistic description of residual stresses, a thermo-chemo-mechanical constitutive model is introduced in the present work and presented for the multi-scale analysis of residual stress patterns. In this context, the analysis of representative unit cells with regular and stochastic distribution of fibers gives information about the associated deformation and stress fields. Dehomogenization at macroscopically highly stressed regions, characterized by local stress peaks, reveals the effect of gradient deformation in the microstructure. Another aspect of this work is the development of FFT-based Galerkin methods, which allows an evaluation of the effect of defect densities, heterogeneities and morphologies on the applicability of the incremental hole drilling method. It could be demonstrated that the incremental hole drilling method is particularly sensitive to defects running along the surface. - lang: ger text: Eigenspannungen in direktgefügten Werkstoffverbunden aus Stahl und kohlenstofffaserverstärktem Epoxidharz reduzieren die Grenzschicht- und Verbundfestigkeit und sind somit für die Festigkeitsbeurteilung von Strukturen zwingend zu berücksichtigen. Zur ganzheitlichen Beschreibung von Eigenspannungen wird in der vorliegenden Arbeit ein thermo-chemo-mechanisches Konstitutivmodell für die skalenübergreifende Bewertung von Eigenspannungsverteilungen vorgestellt. Die Analyse von repräsentativen Einheitszellen mit regulärer und stochastischer Verteilung von Fasern liefert in diesem Zusammenhang Informationen über die zugehörigen Deformations- und Spannungsfelder. Die Dehomogenisierung an makroskopisch hochbelasteten Bereichen, die durch lokale Spannungsüberhöhungen gekennzeichnet sind, zeigt die Auswirkung der gradientenbehafteten Deformation in der Mikrostruktur. Ein weiterer Aspekt dieser Arbeit ist die Entwicklung FFT-basierter Galerkin-Methoden, die es erstmalig erlauben, eine Bewertung der Auswirkung von Defektdichte, Heterogenität und Morphologie auf die Anwendbarkeit der inkrementellen Bohrlochmethode vorzunehmen. Es konnte nachgewiesen werden, dass die inkrementelle Bohrlochmethode insbesondere auf an der Oberfläche verlaufende Defekte sensitiv reagiert. author: - first_name: Steffen Rainer full_name: Tinkloh, Steffen Rainer last_name: Tinkloh citation: ama: Tinkloh SR.

As a subset of additive manufacturing (AM), the DED process, also referred to as laser metal deposition (LMD), enables precise, layer-by-layer material deposition, making it highly suitable for complex geometries and part repair applications. Critical parameters, such as the laser power, feed rate, powder mass flow, and substrate temperature govern the deposition process, impacting the bead height, width, contact angle, and dilution. Inconsistent control over these variables can lead to defects, such as poor bonding, dimensional inaccuracies, and material weaknesses, ultimately compromising the final product. This paper investigates the effects of various process parameters, specifically the substrate temperature, on bead track geometry in DED processes for stainless steel (1.4404). A specialized experimental setup, integrated within a DED machine, facilitates the controlled thermal conditioning of sample sheets. Using Design of Experiments (DoE) methods, individual bead marks are generated and analyzed to assess geometric characteristics. Regression models, including both linear and quadratic approaches, are constructed to predict machine parameters for achieving the desired bead geometry at different substrate temperatures. Validation experiments confirm the accuracy and reliability of the models, particularly in predicting the bead height, bead width, and contact angle across a broad range of substrate temperatures. However, the models demonstrated limitations in accurately predicting dilution, indicating the need for further refinement. Despite some deviations in measured values, successful fabrication is achieved, demonstrating robust bonding between the bead and substrate. The developed models offer insights into optimizing DED process parameters to achieve desired bead characteristics, advancing the precision and reliability of additive manufacturing technology. Future work will focus on refining the regression models to improve predictions, particularly for dilution, and further investigate non-linear interactions between process variables. article_number: '1353' article_type: original author: - first_name: Deviprasad full_name: Chalicheemalapalli Jayasankar, Deviprasad id: '49504' last_name: Chalicheemalapalli Jayasankar orcid: https://orcid.org/ 0000-0002-3446-2444 - first_name: Stefan full_name: Gnaase, Stefan id: '25730' last_name: Gnaase - first_name: Dennis full_name: Lehnert, Dennis id: '90491' last_name: Lehnert - first_name: Artur full_name: Walter, Artur last_name: Walter - first_name: Robin full_name: Rohling, Robin last_name: Rohling - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: 'Chalicheemalapalli Jayasankar D, Gnaase S, Lehnert D, Walter A, Rohling R, Tröster T.

This points to a substantial opportunity for further optimization in material savings and process design. The current study delves into the advancement of sustainable manufacturing practices in the automotive industry, emphasizing the crucial role of lightweight construction concepts and AM technologies in enhancing resource efficiency and reducing greenhouse gas emissions. By exploring the integration of novel AM techniques such as selective laser melting (SLM) and laser metal deposition (LMD), the study aims to overcome existing limitations like slow build-up rates and limited component resolution. The study’s core objective revolves around the development and validation of a continuous process chain that synergizes different AM routes. In the current study, the continuous process chain for DMG MORI Lasertec 65 3D’s LMD system and the DMG MORI Lasertec 30 3D’s was demonstrated using 316L and 1.2709 steel materials. This integrated approach is designed to significantly curtail process times and minimize component costs, thus suggesting an industry-oriented process chain for future manufacturing paradigms. Additionally, the research investigates the production and material behavior of components under varying manufacturing processes, material combinations, and boundary layer materials. The culmination of this study is the validation of the proposed process route through a technology demonstrator, assessing its scalability and setting a benchmark for resource-efficient manufacturing in the automotive sector. article_number: '772' article_type: original author: - first_name: Deviprasad full_name: Chalicheemalapalli Jayasankar, Deviprasad id: '49504' last_name: Chalicheemalapalli Jayasankar orcid: https://orcid.org/ 0000-0002-3446-2444 - first_name: Stefan full_name: Gnaase, Stefan id: '25730' last_name: Gnaase - first_name: Maximilian Alexander full_name: Kaiser, Maximilian Alexander id: '72351' last_name: Kaiser orcid: 0009-0008-1333-3396 - first_name: Dennis full_name: Lehnert, Dennis id: '90491' last_name: Lehnert - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: 'Chalicheemalapalli Jayasankar D, Gnaase S, Kaiser MA, Lehnert D, Tröster T.

These two components can therefore be joined using the intrinsic joining technique, which is formed by curing the matrix of the FRP component. In this study, for the hybrid joint, unidirectionally pre-impregnated semi-finished products (prepregs) with duromer matrix resin and micro-alloyed HC340LA steel were used. In order to conduct a detailed investigation, the damage mechanisms of intrinsically produced fibre metal laminates (FMLs), a new clamping device, and a novel pressing tool were designed and put into operation. The prepregs were prestressed by applying a preloading force using a specially designed prestressing frame. Hybrid specimens were then produced and subjected to nanoindentation and a shear tensile test. In particular, the effect of the residual stress state by varying the defined prestressing force on the damage mechanisms was studied. The results showed that no fracture patterns occurred in the interface of the specimens without preloading as a result of curing at 120 °C, whereas specimens with preloading failed at the boundary layer in the tensile range. Nevertheless, all specimens cured at 160 °C failed at the boundary layer in the tensile range. Furthermore, it was proven that the force and displacement of the preloaded specimens were promisingly higher than those of the unpreloaded specimens. article_number: '316' article_type: original author: - first_name: Hayrettin full_name: Irmak, Hayrettin id: '75657' last_name: Irmak orcid: https://orcid.org/0009-0009-6267-2957 - first_name: Steffen Rainer full_name: Tinkloh, Steffen Rainer id: '72722' last_name: Tinkloh - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten orcid: 0009-0001-6433-7839 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Irmak H, Tinkloh SR, Marten T, Tröster T.

The design and calculation of steel flanges is easy to handle with the help of EN 1591-1 and EN 13555. However, these standards are not suitable in their current form for thermoplastic sealing joints, such as those used in natural gas supply. For this reason, lengthy and cost-intensive tests must currently be carried out to verify tightness and strength. The aim of a doctoral project is to develop a time-efficient and cost-effective analytical calculation method based on the existing standards. For this purpose, the energy-elastic material parameters of the steel must be replaced by elastoplastic material parameters of the thermoplastics and the calculation algorithm adapted accordingly. The problem is to be investigated with the aid of numerical structural simulations (FEM) and experimental tests." author: - first_name: Finn full_name: Bartmann, Finn last_name: Bartmann - first_name: Alexander full_name: Riedl, Alexander last_name: Riedl - first_name: Elmar full_name: Moritzer, Elmar id: '20531' last_name: Moritzer citation: ama: 'Bartmann F, Riedl A, Moritzer E.

Racism is also evident in the depiction of\r\nJesus Christ, who traditionally is portrayed as 'white' in Christian art, although he must be read\r\nbiblically as a Person of Color (PoC). Examples such as the “Wales Window for Alabama” (1964)\r\nby Ronald John Petts and the contemporary icon by Kelly Latimore “Christ in The Rubble” (2023)\r\nshow Jesus as PoC and address racism and social justice. Children’s Bibles continue to be\r\ndominated by ‘white’ depictions of Jesus and the people around him. Works such as the chil-\r\ndren’s Bibles by Desmond Tutu (lyrics) / Laure Fournier et al.

Business reputation ecosystems are a widely untapped research field. In these ecosystems, agents can selectively exchange (monetary) ratings to in-form about the experienced quality in a market. We build a model for conducting a multi-agent simulation that can be used to simulate and evaluate business rep-utation ecosystems as a new system class. We explore the factual occurring vol-untary payment to create positive (pay) or negative ratings (no pay), selling rat-ings selectively to alleviate information asymmetry, and the workings of counter-ratings to prevent buyers' dishonest ratings. Thereby, we analyze, among others, agent profitability, the occurrence of dishonest ratings, and reputation bias and sensitivity. The results provide simulation-based empirical evidence that the con-cept of monetary reputation systems provides necessary incentives for participa-tion, and high-quality sellers and honest buyers benefit from such a system. The results indicate that counter-ratings prompt buyers author: - first_name: Ulvi full_name: Ibrahimli, Ulvi last_name: Ibrahimli - first_name: Simon full_name: Hemmrich, Simon last_name: Hemmrich - first_name: Simon full_name: Zauke, Simon last_name: Zauke - first_name: Axel full_name: Winkelmann, Axel last_name: Winkelmann citation: ama: 'Ibrahimli U, Hemmrich S, Zauke S, Winkelmann A.
