Original Abstract
A three-dimensional model of F-R patterns was constructed by means of stereophotogrammetry in the scanning electron microscope and the basic geometrical rules of F-R formation were identified. The theoretical analysis revealed that the F-R initiates by elementary mode I branches of semi-elliptical surface cracks growing under mixed-mode II + III as a result of the synergy effect. The fact that F-R patterns are usually not observed in the low-cycle fatigue region is also explained.
