Stereofractographic Studies of a Fatigue Crack Propagation in a Low-Carbon Steel

Conference paper

Summary

Stereofractographic method is recommended for the analysis of the fatigue fracture three-dimensional microrelief and for the estimation of the area of true free surface formed at fracture. A new calculating formula for the estimation of microrelief excesses is proposed and the restrictions on the survey parameters connected with the physiological stereoscopic capabilities of human eyes are defined. Quantitative variations of the fatigue striations spacing and height are analyzed according to loading conditions.
