The report describes the continued experimental research on material behavior under fatigue testing. Cycles-to-failure testing was accomplished on fine wire, 0.040 inch diameter, made of AISI 4130, 1038, 1018 and 4340 steel. Cycles-to-failure testing was performed on AISI 4130 steel grooved rod, 0.0937 inch base diameter. Also, endurance strength, staircase tests were accomplished on AISI 1038 steel grooved rods of 0.2700 inch base diameter. These endurance strength results were used in a notch sensitivity analysis described herein. Axial fatigue testing was done on AISI 1018 steel grooved rods to generate a Goodman strength diagram. Comparison of the experimental diagram with two theoretical diagram is described. The results of all testing were analyzed to determine the distributional parameters.
