Abstract

TRADITIONAL FATIGUE LIMIT MEASUREMENTS ARE EXPENSIVE AND TIME CONSUMING, REQUIRING A LARGE NUMBER OF SPECIMENS AND A LONG TIME TO BE COMPLETED. AN ALTERNATIVE APPROACH IS USED IN THIS WORK TO OBTAIN THE FATIGUE LIMIT OF A COLD DRAWN STEEL, IN A ROTATING BEND-ING MACHINE, BY MONITORING TEMPERATURE VARIATIONS INDUCED BY DIFFERENT LOAD RANGE LEVELS IN JUST A FEW SPECIMENS. COMPARISONS WITH DIXON’S TRADITIONAL UP-AND-DOWN METHOD CONFIRM THAT THIS THERMOGRAPHIC APPROACH IS INDEED A MUCH MORE EFFICIENT, FASTER, AND CHEAPER METHOD TO OBTAIN FATIGUE LIMITS.
