Purpose of test
The test yields characteristics, from which the mechanical behaviour of materials or structural elements under constant or repeated pulsating or alternating loading can be derived. It is termed a continuous vibration test (short: f a t i g u e t e s t 1, because the loading at the specimen is applied in form of vibration 1). The borderline case of a single long-time, ¡.e. static load (vibrations with infinitely small amplitude) is not dealt with here 2).
1) Here the term "vibration" is meant comprehensively, ¡.e. in the sense of a periodic variation with time of a process (see DIN 1311). not in the narrower sense of the theory of oscillations of a system having mass. In the latter theory the term "oscillation coefficient" has been developed. It is used in the calculation of structures under load variable with time (for example bridges under traffic load). The coefficient controls the increase of stress by mechanical vibrations.
2) Compare with DIN 50 119 "Testingof materials; creep test, definitions, symbols, procedure, evaluation".
