- Abstract
- The results of fatigue tests of metallic plates of D16T with stress concentrators in the form of a diamond-shaped cut-out on the basis if cycles 103. Diagnosis of fatigue cracking of the surface was carried out by differential contact potential difference and CCTV. Amplitude and time dependence of the contact potential for a variety of cycling intervals were processed using Fourier analysis.
