Abstract:
To study the processes of forming and growing embryonic fatigue cracks in steel EI-847 when tested under a uniaxial tension at constant load; adapting the method of scanning contact potentiometry using the INSTRON-5982 machine. The embryo was detected on the sample surface- in the yield point- and stably tracked by the
equipment indications at higher loads up to the fracture point.
Keywords: scanning contact potentiometry, electrical non-destructive testing, tension testing, fatigue crack, time-frequency signal analysis.
