FATIGUE PROPAGATION IN A514 BASE PLATE AND WELDED JOINTS

FATIGUE STUDIES OF A514 BASE TYPE PLATE MATERIAL AND ASSOCIATED WELDMENTS REVEALED THAT THE FATIGUE CRACK GROWTH RATE WAS PRIMARILY A FUNCTION OF THE APPLIED STRESS INTENSITY RANGE. CRACK GROWTH RATES WERE NOT FOUND TO BE SENSITIVE TO SPECIMEN CONFIGURATION OR MATERIAL THICKNESS. CRACK PROPAGATION STUDIES IN TRANSVERSE WELDMENTS AND THE ASSOCIATED HEAT AFFECTED ZONE REVEALED POSSIBLE RESIDUAL STRESS EFFECTS IN CERTAIN PLATES WHERE FATIGUE CRACK PROPAGATION RATES WERE FOUND TO BE CONSIDERABLY SLOWER THAN ANTICIPATED. /DOT/
