These can include operating vehicles that differ regarding their characteristics and application profile from privately owned cars in motorized individual transport. Studies on life cycle assessment and life cycle engineering of vehicle lightweight structures are mainly limited to these privately owned cars and the impact category of climate change. In this paper, a method for life cycle assessment-based engineering of lightweight structures in vehicles for various mobility system applications, including on-demand mobility services, is developed. The method enables the holistic life cycle assessment of lightweight structures in different mobility system applications considering parameter changes at the upstream products, component, subsystem, vehicle and mobility system levels, as well as the integration of results into engineering activities. A case study is used to show that the vehicle and mobility system application of lightweight structures can significantly influence their environmental impacts and the selection of ecologically preferable product designs. The application in vehicles for on-demand mobility services can lead to an increase in absolute use stage energy demand and environmental impacts compared to applications in privately owned vehicles for motorized individual transport. However, normalized to the transport performance provided, the lifecycle environmental impacts of structural components in vehicles for on-demand mobility services can be lower than in vehicles for motorized individual transport. The paper contributes methodically and with quantitative results to improved decision making in life cycle engineering activities for lightweight structures in mobility system applications."}],"date_created":"2025-08-06T06:53:27Z","publisher":"Elsevier BV","title":"Life cycle engineering of lightweight structures in vehicles for on-demand mobility services","quality_controlled":"1","year":"2025","user_id":"44763","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"project":[{"grant_number":"19S23003Q","name":"NeMobil: NeMo.bil – System kooperierender Fahrzeuge für einen individualisierten Öffentlichen Verkehr","_id":"780"},{"grant_number":"005-2111-0020 ","name":"Climate bOWL: Climate bOWL: Climate neutral Business in Ostwestfalen-Lippe","_id":"405"}],"_id":"60885","article_type":"original","article_number":"101058","type":"journal_article","status":"public","author":[{"first_name":"Moritz","full_name":"Ostermann, Moritz","id":"44763","last_name":"Ostermann","orcid":"https://orcid.org/0000-0003-1146-0443"},{"last_name":"Dierkes","full_name":"Dierkes, Eric","first_name":"Eric"},{"full_name":"Marten, Thorsten","id":"338","last_name":"Marten","orcid":"0009-0001-6433-7839","first_name":"Thorsten"},{"last_name":"Tröster","id":"553","full_name":"Tröster, Thomas","first_name":"Thomas"}],"volume":28,"date_updated":"2025-08-07T06:41:28Z","oa":"1","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S2666790825001818?via%3Dihub","open_access":"1"}],"doi":"10.1016/j.clet.2025.101058","publication_status":"published","publication_identifier":{"issn":["2666-7908"]},"citation":{"short":"M.

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.

Due to an increasing volume of shipments, there is a significant need for more delivery vehicles. One approach to reduce the associated increase in carbon dioxide (CO2) emissions is a new light weight design approach involving the substitution of conventional materials with glass fiber mat-reinforced thermoplastics (GMT) based on polypropylene (PP). The application of GMT by compression molding is a widely used process in the automotive industry. However, application in the commercial vehicle sector requires much larger dimensions, making it necessary to clarify whether the manufacturing process and material are suitable for semi-structural applications on this scale. To find this out, two replacement geometries are abstracted in this study and manufactured by varying the main manufacturing parameters. The feasibility can be demonstrated by recording and analyzing the resulting process variables and measuring the formed fiber distribution. At the end of the paper, recommendations are given for the production of GMT structures on the scale of commercial vehicles. </jats:p>"}],"keyword":["Compression Molding","Fiber Content","Process Development","Lightweight Design"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2023","publisher":"Materials Research Forum LLC","date_created":"2023-04-24T14:14:11Z","title":"Feasibility Study of Compression Molding for Large Reinforcement Structures in the Commercial Vehicle Sector","type":"conference","status":"public","_id":"44154","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"user_id":"45543","publication_identifier":{"eissn":["978-1-64490-247-9"]},"publication_status":"published","page":"249-258","intvolume":"        28","citation":{"apa":"Lückenkötter, J., Leimbach, J.

First approaches for integrating future scenarios for these key factors into LCE already exist, but they only consider a limited number of parameters and scenarios. This work aims to develop a method that can be practically applied in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive components, considering relevant parameters and consistent scenarios. Therefore, pLCA methods are further developed to investigate the influence of future scenarios on the GHG emissions of automotive components. The practical application is demonstrated for a vehicle component with different design options. This paper shows that different development paths of the foreground and background system can shift the ecological optimum of design alternatives. Therefore, future pathways of relevant parameters must be considered comprehensively to reduce GHG emissions of future vehicles.

Rivets for self-piercing riveting differ in their geometry, the material used, the condition of the material and their surface condition. To shorten the manufacturing process by omitting the heat treatment and the coating process, the authors have elaborated a concept for the use of stainless steel with high strain hardening as a rivet material. The focus of the present investigation is on the evaluation of the influences of the rivet’s geometry and material on its deformation behaviour. Conventional rivets of types P and HD2, a rivet with an improved geometry made of treatable steel 38B2, and rivets made of the stainless steels 1.3815 and 1.4541 are examined. The analysis is conducted by means of multi-step joining tests for two material combinations comprising high-strength steel HCT70X and aluminium EN AW-5083. The joints are cut to provide a cross-section and the deformation behaviour of the different rivets is analysed on the basis of the measured changes in geometry and hardness. In parallel, an examination of the force-stroke curves provides further insights. It can be demonstrated that, besides the geometry, the material strength, in particular, has a significant influence on the deformation behaviour of the rivet. The strength of steel 1.4541 is seen to be too low for the joining task, while the strength of steel 1.3815 is sufficient, and hence the investigation confirms the capability of rivets made of 1.3815 for joining even challenging material combinations.","lang":"eng"}],"editor":[{"first_name":"Glenn","full_name":"Daehn, Glenn","last_name":"Daehn"},{"first_name":"Jian","last_name":"Cao","full_name":"Cao, Jian"},{"full_name":"Kinsey, Brad","last_name":"Kinsey","first_name":"Brad"},{"last_name":"Tekkaya","full_name":"Tekkaya, Erman","first_name":"Erman"},{"first_name":"Anupam","last_name":"Vivek","full_name":"Vivek, Anupam"},{"full_name":"Yoshida, Yoshinori","last_name":"Yoshida","first_name":"Yoshinori"}],"status":"public","type":"book_chapter","publication":"Forming the Future - Proceedings of the 13th International Conference on the Technology of Plasticity.

Aiming to enhance the social relevance, usability and sustainability of technological products and solutions, society and public institutions such as research funding organizations increasingly expect engineers to include inter- and transdisciplinary approaches into the development of new technologies. Engineering research and education, however, are particularly challenging areas to realize inter- and transdisciplinary collaborations, for manifold reasons.\r\nThis contribution presents methods and results of an inter- and transdisciplinary research and education strategy designed to meet the particular requirements of engineers and engineering students. It starts with a brief discussion of typical challenges regarding inter- and transdisciplinary approaches in engineering (research topics, research culture, skills, time, and barriers of lay people to involve in technology development). Secondly, it presents the methods developed to overcome those challenges within the context of the NRW Fortschrittskolleg \"Light - Efficient - Mobile\" (FK LEM). Founded in 2014, the FK LEM is a PhD programm focuses on lightweight construction, but with a special emphasis on how lightweight technologies are connected to different areas of society, to societal actors and technology users, and to the needs of a diversity of social groups. In order to explore these connections, we organized three workshops to bring public service, civil society, industry, practitioners and engineers together to discuss the perceived needs in those areas, and the potential of lightweight solutions. Topically, the workshops were dedicated to the fields of Rescue & Security Services; Care, Mobility & Assisted Living; and Sustainable Ressources & Climate Protection. Methodologically, we applied a pragmatic but valid approach to focus groups and discourse analysis. Results of the workshops in terms of directions for future research, epistemological and ethical dimensions of lightweight engineering are presented in the third part of our contribution. Finally, we discuss how our method and experience can be transferred into other engineering and educational contexts. With other words, how empowering students, engineers and the public to involve in inter- and transdisciplinary engineering processes can be achieved, and how this empowerment supports the development of innovative technologies as well as engineers’ skills to design technology in line with societies’ needs and challenges."}]}]
