[{"language":[{"iso":"eng"}],"abstract":[{"text":"In order to follow the 1.5 degree path of the Paris Climate Agreement, drastic greenhouse gas reduction measures are needed in the transport sector. The potential of public transport and new mobility services to reduce transport-related greenhouse gas emissions cannot yet be fully exploited, especially in rural regions. This paper presents the concept of an innovative mobility system, called NeMo.bil, that intends to fill the gap between individual and public transport to create a demand-oriented and sustainable mobility offer. The concept is based on convoy formation of autonomously driving lightweight vehicles serving the first and last mile and a larger towing vehicle carrying enough power and energy to move the convoy over longer distances at higher speeds. This combination of two different vehicles, intelligently controlled by a digital ecosystem, aims to significantly increasing energy, resource and cost efficiency. Based on an analysis of previous approaches for innovative mobility solutions, the concept is derived from a technical and sociological perspective and its potential for reducing energy demand is calculated.","lang":"eng"}],"publication":"Towards the New Normal in Mobility","title":"Individualization of Public Transport – Integration of Technical and Social Dimensions of Sustainable Mobility","publisher":"Springer Fachmedien Wiesbaden","date_created":"2023-05-05T07:19:14Z","year":"2023","quality_controlled":"1","_id":"44502","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"user_id":"44763","editor":[{"full_name":"Proff, Heike","last_name":"Proff","first_name":"Heike"}],"status":"public","type":"book_chapter","conference":{"end_date":"2022-06-23","location":"Duisburg","name":"14.

Additive manufacturing processes, in particular powder-based selective laser melting, are used to produce metallic additive manufactured components for the automotive and aerospace industries. Different materials are often joined together to realize sustainable lightweight construction. The production of such mixed construction joints is often realized using mechanical joining technology (e.g. self-piercing riveting). However, there is currently very little experience with the mechanical joining of metallic additive manufacturing components. Furthermore, there is insufficient knowledge about the effects that occur during the mechanical joining of additive manufacturing components. In this article, a method is presented to investigate the joinability of additively manufactured components with conventionally manufactured components using a numerical simulation of the self-piercing riveting process. For this purpose, the additive manufacturing materials are characterized experimentally, the simulation model is configured, and the joining process with additive manufacturing materials is represented in the numerical simulation. Furthermore, the influence of the building direction on the mechanical properties is shown using miniature tensile specimens. Besides the configuration of the simulation model, the influence of heat treatment on the self-piercing riveting process is presented. </jats:p>","lang":"eng"}],"date_created":"2023-02-28T10:52:49Z","author":[{"first_name":"Per","last_name":"Heyser","id":"40450","full_name":"Heyser, Per"},{"first_name":"Rudolf","last_name":"Petker","full_name":"Petker, Rudolf"},{"orcid":"0000-0002-2763-1246","last_name":"Meschut","id":"32056","full_name":"Meschut, Gerson","first_name":"Gerson"}],"publisher":"SAGE Publications","date_updated":"2023-02-28T10:55:03Z","doi":"10.1177/14644207231158213","title":"Development of a numerical simulation model for self-piercing riveting of additive manufactured AlSi10Mg","publication_identifier":{"issn":["1464-4207","2041-3076"]},"quality_controlled":"1","publication_status":"epub_ahead","citation":{"ama":"Heyser P, Petker R, Meschut G.

Under circularly polarized excitation at a specific wavelength, the L-shape antennas with rotating orientation angle act as spatially variant three-dimensional tilted dipoles and are able to generate desire phase delay for different polarization components.

The production of lightweight materials is usually associated with an increase in energy demand, so the environmental impacts of lightweight structures need to be assessed holistically using a life cycle assessment. To estimate the life cycle environmental impacts of a product in its developmental stage, for example, by life cycle engineering, future changes in relevant influencing factors must be considered. Prospective life cycle assessment provides methods for integrating future scenarios into life cycle assessment studies. However, approaches for integrating prospective life cycle assessment into product development are limited. The objective of this work is to provide the methodological foundation for integrating future scenarios of relevant influencing factors in the development of lightweight structures. The applicability of the novel methodology is demonstrated by a case study of a structural component in a steel, aluminium, and hybrid design. The results show that appropriate decarbonisation measures can reduce the life cycle greenhouse gas emissions by up to 95 percent until 2050. We also found that shifts in the environmentally optimal design are possible in future scenarios.

In order to reduce global energy consumption in production and industry along with the associated CO2 emissions, existing resources must be used more efficiently. This includes the energy-efficient and comprehensive recycling of a wide range of metals. Especially for the production of aluminium, there is a large potential for saving energy using efficient recycling processes. With regard to the recycling of aluminium studies have shown that solid-state recycling processes are significantly more efficient considering the used energy and resources compared to the conventional, smelting-metallurgical recycling process. In this paper, the direct and energy-efficient friction-induced recycling process (FIRP) based on the conform process is further described and analysed in terms of the temperature-property relationships. For this purpose, the influence of the processing temperature on the microstructure and properties of the recycled semi-finished products is investigated using the toll system that enables an ECAP forming. Specific sections of the (in theory) infinite, recycled semi-finished product are taken and analysed at different process temperatures of the solid state recycling process. Based on these sections, the properties in terms of mechanical hardness, strength, ductility and grain size are analysed and a degressive relationship between process temperature and mechanical hardness up to a temperature of 270 °C can be shown. Applying the Hall-Petch relationship, it is analysed whether there is a correlation between the strength and the microstructure in the form of the grain size. </jats:p>","lang":"eng"}],"status":"public","type":"conference","publication":"Materials Research Proceedings","keyword":["Recycling","Aluminium","Friction-Induced","Energy Efficiency"],"language":[{"iso":"eng"}],"_id":"44036","user_id":"83141","department":[{"_id":"156"}],"year":"2023","citation":{"ama":"Borgert T, Homberg W.

This paper presents new process designs for energy and resource-efficient forming of gas cylinders by friction-spinning without the use of an external heat supply. The self-generated heat enables friction-spinning process to reduce the energy demand in the manufacture of gas cylinders, which are usually manufactured with external heat (mostly fossil fuels), by 95 %. Typical gas cylinder contours, such as flattened and spherical bottom ends and cylinder necks, are manufactured by friction-spinning of AW 6060 tubular profiles with specifically designed tool path strategies. It is shown that friction-spinning enables the manufacture of typical gas cylinder contours with sufficient wall thickness and the required gas tightness without the input of external heat. Thus, this process can contribute to an increase in the energy and resource efficiency of forming processes. </jats:p>"}],"status":"public","date_updated":"2023-04-27T10:30:44Z","publisher":"Materials Research Forum LLC","date_created":"2023-04-17T07:40:54Z","author":[{"first_name":"Frederik","last_name":"Dahms","id":"64977","full_name":"Dahms, Frederik"},{"id":"233","full_name":"Homberg, Werner","last_name":"Homberg","first_name":"Werner"}],"title":"Energy and Resource-efficient Forming of Gas Cylinders by Friction-Spinning","doi":"10.21741/9781644902479-208","conference":{"start_date":"2023-04-19","name":"ESAFORM 2023","location":"Krakau","end_date":"2023-04-21"},"publication_identifier":{"issn":["2474-395X"]},"quality_controlled":"1","publication_status":"published","related_material":{"link":[{"relation":"confirmation","url":"https://www.mrforum.com/product/9781644902479-208/"}]},"year":"2023","citation":{"apa":"Dahms, F., &#38; Homberg, W.

Knowledge on the thermal conductivity of paraffins is necessary for the design and optimization of heat storage systems. However, for most paraffins solely the thermal conductivity of the liquid state has been sufficiently investigated. For the solid state, precise thermal conductivity data are only known for a few paraffins, while only generalized values are available for the remainder, some of which contradict each other. In this study, a measurement setup based on the modified guarded hot plate method is developed. It is used to investigate the thermal conductivity of several paraffines in the solid state, including pure n-docosane and its compounds with different types and concentrations of graphite. For n-docosane in the solid state, the thermal conductivity is determined to be 0.49 W/(m K). A particle size of 200 μm with a spherical shape turns out to be optimal to increase the thermal conductivity. This allows the thermal conductivity of a compound with 10% graphite to increase by a factor of three compared to the pure paraffin. Furthermore, significant differences to thermal conductivity data from the literature are found."}],"type":"journal_article","publication":"Journal of Thermal Analysis and Calorimetry","language":[{"iso":"eng"}],"keyword":["Physical and Theoretical Chemistry","Condensed Matter Physics"],"user_id":"7828","department":[{"_id":"728"},{"_id":"145"},{"_id":"393"},{"_id":"9"}],"_id":"43391"},{"quality_controlled":"1","publication_identifier":{"isbn":["978-3-932715-55-6"]},"publication_status":"published","corporate_editor":["Deutscher Kälte‐ und Klimatechnischer Verein e.V."],"citation":{"apa":"Paul, A., Baumhögger, E., Elsner, A., Reineke, M., Kasper, T., Schumacher, D., Vrabec, J.,  Hüppe, C.,  Stamminger, R., Hölscher, H., Stoll, R., Wagner, H.,  Gries, U., &#38; Becker, W.

Aus früheren Untersuchungen ist bekannt, dass durch verschiedene technische Alterungsmechanismen der Energieverbrauch über eine Produktlebensdauer von 18 Jahren um bis zu 33 % zunehmen kann. Ziel des vom BMWi geförderten Projekts ALGE war es, die verschie-denen Ursachen und Einflussgrößen für die Alterung von Haushaltskältegeräten zu ermitteln und eine Alterungs-funktion zu bestimmen, die den zeitlichen Verlauf des zunehmenden Energieverbrauchs beschreibt.\r\nIn diesem Projekt wurde das Alterungsverhalten von Haushaltskältegeräten durch 100 Normenergieverbrauchs-messungen an 32 real gealterten Geräten untersucht. Aus den gewonnenen Ergebnissen konnte eine Alterungs-funktion bestimmt werden, die den Anstieg des Energieverbrauchs beschreibt. Alle untersuchten Geräte wurden an der Universität Paderborn im Neuzustand vermessen und nach einer Laufzeit von bis zu 21 Jahren erneut geprüft. Bereits nach einem zweijährigen Betrieb konnte ein Mehrverbrauch von bis zu 11 % festgestellt werden. Über die durchschnittliche Produktlebensdauer von Haushaltskältegeräten von ca. 16 Jahren steigert sich der Energieverbrauch um durchschnittlich 27 %.\r\nIm Rahmen des Projekts wurden verschiedene Systemkomponenten, wie Isolierung und Verdichter, hinsichtlich ihres Alterungsverhaltens untersucht. Bei dem im Gehäuse als Isolierung verwendeten PUR-Schaum konnte über einen Zeitraum von 31 Monaten ein Anstieg der Wärmeleitfähigkeit von 19,5 W/(m⋅K) auf 24,5 W/(m⋅K) festge-stellt werden. Zur Untersuchung der Alterung der Verdichter wurden zuvor auf einem Kalorimeterteststand ver-messene Verdichter in Geräte eingebaut. Nach einem zweijährigen Betrieb wurden diese Verdichter wieder aus-gebaut und erneut vermessen. Hierbei konnte keine Änderung des COP festgestellt werden. Zusätzlich zu den technischen Parametern wurde der Einfluss des Verbraucherverhaltens analysiert. Hier zeigte sich, dass bis zu 33 % des Gesamtenergieverbrauchs nach einer mehrjährigen Nutzungsdauer verbraucherinduziert sein können.","lang":"ger"}],"department":[{"_id":"728"},{"_id":"9"}],"user_id":"7828","_id":"43394","language":[{"iso":"ger"}],"keyword":["Haushaltskältegeräte","Energieverbrauch","Alterung","Verdichter","PUR-Schaum"]},{"abstract":[{"text":"<jats:title>Abstract</jats:title>\r\n               <jats:p>The accessibility to rheological parameters for concrete is becoming more and more relevant. This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values. Therefore, we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement of fresh concrete with particles up to <jats:inline-formula>\r\n                     <jats:alternatives>\r\n                        <jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" xlink:href=\"graphic/j_arh-2022-0140_eq_001.png\" />\r\n                        <m:math xmlns:m=\"http://www.w3.org/1998/Math/MathML\">\r\n                           <m:msub>\r\n                              <m:mrow>\r\n                                 <m:mi>d</m:mi>\r\n                              </m:mrow>\r\n                              <m:mrow>\r\n                                 <m:mi mathvariant=\"normal\">max</m:mi>\r\n                              </m:mrow>\r\n                           </m:msub>\r\n                           <m:mo>=</m:mo>\r\n                           <m:mn>5.5</m:mn>\r\n                           <m:mspace width=\".5em\" />\r\n                           <m:mi mathvariant=\"normal\">mm</m:mi>\r\n                        </m:math>\r\n                        <jats:tex-math>{d}_{{\\rm{\\max }}}=5.5\\hspace{.5em}{\\rm{mm}}</jats:tex-math>\r\n                     </jats:alternatives>\r\n                  </jats:inline-formula>. The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones.</jats:p>","lang":"eng"}],"publication":"Applied Rheology","keyword":["Condensed Matter Physics","General Materials Science"],"language":[{"iso":"eng"}],"year":"2023","quality_controlled":"1","issue":"1","title":"Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete","publisher":"Walter de Gruyter GmbH","date_created":"2023-03-16T19:06:49Z","status":"public","type":"journal_article","_id":"43034","department":[{"_id":"150"}],"user_id":"3959","intvolume":"        33","citation":{"chicago":"Josch, Sebastian, Steffen Jesinghausen, and Hans-Joachim Schmid. “Development of an Adaptive Coaxial Concrete Rheometer and Rheological Characterisation of Fresh Concrete.” <i>Applied Rheology</i> 33, no. 1 (2023). <a href=\"https://doi.org/10.1515/arh-2022-0140\">https://doi.org/10.1515/arh-2022-0140</a>.","ieee":"S.
