EFFECTS OF SURFACE MICROMORPHOLOGY CHARACTERISTICS ON FATIGUE PERFORMANCE OF DOUBLE COLD EXPANDED HOLE

EFFECTS OF SURFACE MICROMORPHOLOGY CHARACTERISTICS ON FATIGUE PERFORMANCE OF DOUBLE COLD EXPANDED HOLE

Established the double cold expansion simulation model, and investigated the effects of surface micromorphology characteristics on the fatigue performance of double cold expanded holes. The double cold expansion process and fatigue life of the strengthened holes was simulated by using ABAQUS and MSC...
