This paper presents a method of identifying fatigue cracking of specimens made of material DD11 based on selected characteristics of the vibration signal. Acceleration of vibrations of the free end of a specimen was taken for an analysis of specimen properties during the process of fatigue cracking. Features which enable identification and monitoring of the process of specimen cross-section cracking...
This paper discusses the method used to identify the process involving fatigue cracking of samples on the basis of selected vibration signal characteristics. Acceleration of vibrations has been chosen as a diagnostic signal in the analysis of sample cross section. Signal characteristics in form of change in vibration amplitudes and corresponding changes in FFT spectrum have been indicated for the...
