- Fatigue Strength of Notched Specimen of Steel under Pulsating Tension
説明
We made axial stress fatigue tests about the specimens which have circumferential notches, made of 0.13%C and 0.63%C steels, under the conditions σm/σa=0, 1, 3, 5, etc., where σm denotes the tensile mean stress and σa the stress amplitude.<br>The summary of the results is as follows:<br>(1) About the notched specimens, the endurance limit line in the endurance limit diagram under axial stress is given by a straight line which passes the two points, the one represents the value of σw on the ordinate and the other represents the value of σT on the abscissa, where σw denotes the endurance limit under completely reversed tension and compression and σT denotes the breaking strength on final area about the notched specimen.<br>(2) About the notched specimen, the inclinations of S-N curves, when the ordinate represents σmax=σm+σa and the abscissa represents number of stress cycles N in logarithmic scale, and each S-N curve is drawn at σm/σa=const., become parallel.<br>(3) Using the conclusions above mentioned, we suggest a method of construction of σmax-σm-N diagram, which gives the safe region of materials under axial load.
