@inbook{59978, abstract = {{In latest body-in-white (BIW) concepts, engineers take into account a wider range of different materials to pursue a multi-material design approach. However, the lightweight potential of common materials like steel, aluminum or even fiber-reinforcement plastics (FRP) is limited. In keeping with the motto “the best material for the best application”, a new approach for a top-down material design is introduced. With the aim to develop an application tailored material, the multi-material concept is adapted for the thickness dimension of the component. Within this contribution a new optimization- based design methodology is applied on a stiffness relevant car body part. Starting with benchmark simulations of a reference BIW structure, a critical car body component is determined by an internal energy based method and a subsequent sensitivity analysis. The identified demonstrator component is later subdivided into multiple layers and submitted to a first optimization loop in which the developed methodology varies the material parameters for each single layer. Once an optimum for the through-thickness properties of the part is found, further optimization loops with concrete material pendants and manufacturing restrictions are carried out. The result is a hybrid laminate part consisting of steel and FRP plies. To achieve a further improvement in body characteristics and lightweight, the investigated part is redesigned by the aim of topology optimization. Finally, the tailored hybrid stacks are validated in BIW simulations and compared with the reference. The optimization-based approach allows a weight reduction up to 25 % while maintaining or even improving the BIW properties.}}, author = {{Camberg, Alan Adam and Stratmann, Ina and Tröster, Thomas}}, booktitle = {{Zukunftstechnologien für den multifunktionalen Leichtbau}}, isbn = {{9783662582053}}, issn = {{2524-4787}}, publisher = {{Springer Berlin Heidelberg}}, title = {{{TAILORED STACKED HYBRIDS – AN OPTIMIZATION-BASED APPROACH IN MATERIAL DESIGN FOR FURTHER IMPROVEMENT IN LIGHTWEIGHT CAR BODY STRUCTURES}}}, doi = {{10.1007/978-3-662-58206-0_12}}, year = {{2019}}, } @inbook{13436, author = {{Camberg, Alan Adam and Stratmann, Ina and Tröster, Thomas}}, booktitle = {{Technologies for economical and functional lightweight design}}, isbn = {{9783662582053}}, issn = {{2524-4787}}, title = {{{TAILORED STACKED HYBRIDS – AN OPTIMIZATION-BASED APPROACH IN MATERIAL DESIGN FOR FURTHER IMPROVEMENT IN LIGHTWEIGHT CAR BODY STRUCTURES}}}, doi = {{10.1007/978-3-662-58206-0_12}}, year = {{2019}}, } @inproceedings{16030, author = {{Triebus, Marcel and Bienia, S. and Marten, Thorsten and Tröster, Thomas and Dröder, K.}}, booktitle = {{Proceedings of 7th International Conference Hot Sheet Metal Forming of High-Performance Steel}}, editor = {{Oldenburg, Mats and Hardell, Jens and Casellas, Daniel}}, isbn = {{978-3-95735-104-3}}, location = {{Lulea, Sweden}}, publisher = {{Verlag Wissenschaftliche Scripten}}, title = {{{Press Hardening Integrated Structuring for Hybrid Components}}}, year = {{2019}}, } @techreport{64186, author = {{Marten, Thorsten and Tröster, Thomas and Salomon, Rainer}}, isbn = {{978-3-946885-33-7}}, publisher = {{Verlag und Vertriebsgesellschaft mbH}}, title = {{{P920 - Einsatz neuartiger Stähle und Generierung gradierter Leichtbaustrukturen im Presshärteprozess}}}, year = {{2019}}, } @inproceedings{19868, author = {{Camberg, Alan Adam and Tröster, Thomas and Sotirov, Nikolay and Tölle, Jörn and Bohner, Friedrich}}, booktitle = {{Materials Science and Engineering (MSE) Congress 2018}}, location = {{Darmstadt}}, title = {{{Investigation of ductility and damage characteristics of EN AW-5182 H18 at non-isothermal forming conditions}}}, year = {{2018}}, } @misc{6594, author = {{Claes, Leander and Zeipert, Henning and Koppa, Peter and Tröster, Thomas and Henning, Bernd}}, title = {{{Additiv gefertigte, akustische Diffusor-Strukturen für Ultraschallanwendungen}}}, year = {{2018}}, } @article{15876, author = {{Camberg, Alan Adam and Engelkemeier, Katja and Dietrich, Jan and Heggemann, Thomas}}, issn = {{2510-2877}}, journal = {{Lightweight Design worldwide}}, number = {{2}}, pages = {{24--29}}, publisher = {{Springer Vieweg}}, title = {{{Top-down design of tailored fiber-metal laminates}}}, doi = {{10.1007/s41777-018-0004-1}}, volume = {{11}}, year = {{2018}}, } @article{15977, author = {{Tasdemirci, Alper and Akbulut Irmak, Emine Fulya and Guzel, Erkan and Tuzgel, Firat and Yucesoy, Atacan and Sahin, Selim and Guden, Mustafa}}, issn = {{0263-8231}}, journal = {{Thin-Walled Structures}}, pages = {{547--555}}, title = {{{Crushing behavior and energy absorption performance of a bio-inspired metallic structure: Experimental and numerical study}}}, doi = {{10.1016/j.tws.2018.07.051}}, year = {{2018}}, } @inproceedings{16034, author = {{Camberg, Alan Adam and Tröster, Thomas}}, booktitle = {{HYBRID - MATERIALS AND STRUCTURES 2018 - PROCEEDINGS}}, isbn = {{978-3-88355-417-4}}, location = {{Bremen}}, publisher = {{DGM - Deutsche Gesellschaft für Materialkunde e.V.}}, title = {{{Optimization-based material design of tailored stacked hybrids for further improvement in lightweight car body structures}}}, year = {{2018}}, } @inproceedings{16039, author = {{Ahlers, Dominik and Tröster, Thomas}}, location = {{Erfurt}}, title = {{{Entwicklung einer Prozessroute für die Luftfahrtindustrie mit erhöhter Aufbaurate im Laserstrahlschmelzprozess von Ti6Al4V}}}, year = {{2018}}, } @inproceedings{16040, author = {{Wang, Z. and Tröster, Thomas}}, location = {{Bologna, Italy}}, title = {{{Influences of interface on the adhesion and corrosion properties of steel-CFRP hybrid structures manufactured by vacuum assisted resin transfer moulding}}}, year = {{2018}}, } @inproceedings{16042, author = {{Triebus, Marcel and Tröster, Thomas and Camberg, Alan Adam and Bienia, S. and Dröder, K.}}, booktitle = {{15.
