Basic mechanisms of creep and the testing methods. (English) Zbl 0929.74098

Ginsztler, János (ed.) et al., Component reliability under creep-fatigue conditions. Wien: Springer. CISM Courses Lect. 389, 87-135 (1998).
Summary: Pointing at the importance of material selection in design process, we discuss the responses of structural materials to loading. The response can be elastic or plastic, or the material can fracture. These physical processes are briefly examined on atomic scale as well as in microscopic and in macroscopic sense. The influence of loading conditions as e.g. temperature or alternating loading are discussed, together with damage processes due to the loading. The usual testing methods are overviewed and the different material characteristics are analyzed. It is shown that, although the testing methods are simple models of the real loading conditions, the most material parameters are not well defined indicators, and therefore their misuse can result in serious mistakes. Finally, we discuss difficulties in fatigue and creep testings.
