Mechanische Eigenschaften verschiedener Lötverfahren im Vergleich zur Laserschweißung kieferorthopädischer Drähte
… Material und Methode: Zur vergleichenden Werkstoffprüfung wurden gefügte kieferorthopädische Drähte herangezogen, die mittels von vier Lötverfahren sowie zwei verschiedenen Nd:Yag-Laserschweißgeräten angefertigt wurden. Es wurden dynamische Versuchsreihen auf Wechselbelastung und statische …

Bestimmung der Materialparameter gefüllter Elastomere in Abhängigkeit von Zeit, Temperatur und Beanspruchungszustand
Within the finite element analysis (FEA) so-called material models are used for the simulation of the mechanical behavior of rubber materials. These material models have to be calibrated with experimentally determined data before a FEA-simulation can be started. A new concept is developed, which …

High temperature mechanical properties of cast as well as powder metallurgical manufactured metallic foams
This work deals with studying the high temperature mechanical properties of different types of metallic foams. The foams which have been used in this work were manufactured by two different processing methods. Al-foams (trade-name Alporas) were processed by a melt metallurgical route whereas …

Integration eines funktionell gradierten W/Cu-Übergangs für Divertorkomponenten von Fusionsanlagen
One of the most difficult topics in the design and development of future fusion devices, e.g. ITER (Latin for "the way") is the field of plasma facing components for the divertor. In steady-state mode these will be exposed to heat fluxes up to 20 MW/m2. The favored design-option is a component made …

Neue Verfahren zur Analyse des Verformungs- und Schädigungsverhaltens von MCrAlY-Schichten im Wärmedämmschichtsystem
Thermal barrier coatings applied to thermally highly loaded areas of land-based gas turbines represent a promising tool to increase efficiency and to reduce emissions in the conventional electric power production. A basic requirement to achieve reliable use of thermal barrier coatings is an …

Zusammenwirken von Beton und Stahlprofil bei kammerbetonierten Verbundträgern
Composite structures consisting of structural steel and concrete maximize the advantages of the two components provided that there is sufficient shear connection. When high strength materials are applied, the positive effect becomes even more apparent. Today, using high strength materials and …
