A sample surface is imaged using a scanning electron microscope to obtain a sample image potentially containing the fatigue striations. A sample image patch potentially containing fatigue striations is selected from the sample image. After normalizing the sample image patch and enhancing line-like regular structures contained in the sample image patch, the normalized image patch is autocorrelated, Radon transformed and spectrally analyzed. The resulting power spectrum of the transformed image patch contains information about striation properties of the fatigue striations contained in the sample image, if any fatigue striations are present. Furthermore, a system for performing the method is disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for determining striation properties of fatigue striations and for determining the presence of fatigue damage","description":"To improve measurement or assessment of fatigue damage to parts, a computer-implemented method for measuring striation properties of fatigue striations on a sample surface of a part is disclosed.
