46702 2017 eng lecture 0 -- -- -- The presentation describes why the issue of thermal drift of extensometers has become important. It shows the possible sources of thermal drift of extensometers. It shows with a simple theoretical example calculation that the permitted strain error in standards can be exceeded if the temperature fluctuation at the extensometer is too high, but this effect remains mostly unknown because of missing data of the extensometer temperature throughout the test. This will be discussed in fatigue standard committees with the aim to improve the quality of fatigue testing results. 8th Int Conf on LCF (LCF8) Dresden, Germany 27.06.2017 29.06.2017 0 Hellmuth Klingelhöffer eng uncontrolled temperature fluctuation of extensometers eng uncontrolled fatigue standard committee Technik, Medizin, angewandte Wissenschaften Datei im Netzwerk der BAM verfügbar ("Closed Access") Präsentation
