Eigenspannungen in Metall-Keramik-Verbunden fiihren haufig zu deren vorzeitigem Versagen. Im vorliegenden Beitrag werden Ergebnisse aus Grundlagenuntersuchungen vorgestellt, bei denen der EinfluS wesentlicher Werkstoffkennwerte untersucht sowie ein Vergleich der Rechenergebnisse rnit Laboruntersuchungen vorgenommen wurde.
Fundamental Investigations of Residual Stresses in
Metal-Ceramic-Joints by FEMThe reduction of damages in metal-ceramic-joints caused by residual stresses is of essential significance. Therefore, a model was created to simulate the behaviour of metal-ceramic-joints under thermal stress. In this paper, results of fundamental investigations are presented.
Engineering is still mainly oriented towards step‐by‐step‐processes. Due to ongoing challenges such as increasing complexity or shortened time for product developments, connections and correlations have to be understood and used as an important part of work in engineering practice as well as in research. Therefore, a tool derived form a holistic model based on a material approach is explained. The subject of lead‐free electronic soldering is taken for illustrating its practical use and potential.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
